JOHNSON State Highway Engineer of Illinois As each State has taken up the problem of highway improvement, there have been found conditions and problems for which the experi- ence gained by States that had already studied the problem did not offer a complete solution. Thus it happened when the Illinois high- way commission understood the study of highway conditions in Illi- nois, they were confronted by the fact that a very large proportion of the money spent for road purposes was for the construction and maintenance of highway bridges, and that there existed among the local officials a desire for assistance in the construction of these struc- tures. The policy was therefore adopted of making a special study of highway bridges. The conditions found in Illinois applied so generally to a large num- ber of States, and the work of the Illinois highway commission in assisting and directing the construction of highway bridges proved of such benefit, that much attention has been attracted to this branch of highway work. The wide spread interest aroused, and the importance of highway bridges are readily understood, when we consider for a moment that the bridges are the essential links connecting many sections of road which would otherwise be absolutely useless. There are now in all sections of the country wide areas well traversed by roads which are much used, and over which practically all descriptions of country highway traffic pass. The mileage of such roads is so great as to preclude the immediate realization of their being covered with an improved, durable road surface. But in the meantime the use of these roads is such as to demand at present a class of highway bridges practically the same as would be demanded were these roads improved. Therefore, we find that the standard that should be adopted for high- HIGHWAY BRIDGES 107 way bridges is necessarily considerably in advance of the standard of road surface in the immediate vicinity; and that in fact the character of the bridge required is practically independent of the nature of the road surface leading to it. The first consideration in the construction of a bridge is the public safety, and its cost must be subservient to this requirement. The engineer far better rest under the criticism that he designed a bridge heavier than immediate needs may require, than to shoulder the responsibility of loss of life through an attempt to economize in the first cost of the structure. The number of bridges in use on our highways today in the well watered areas of the country makes their cost and maintenance a very large proportion of the amount that is raised by the taxpayers for expenditure upon the highway, and while exact data are lacking to show the precise amount relatively spent upon roads and bridges, it can be said in general that in those sections of the country where a majority of the roads is unimproved that the bridge expenditure will average from three-tenths to one-half the total amount raised for road and bridge work. It is evident that the more that is spent upon the roads proper and the higher the cost and standard of road surface maintained in a com- munity the less in proportion will be the bridge cost. And it is a fact that the States first taking up the question of road improvement were those where a greater proportion of money was spent on the road surface. Thus the cost of the bridges appeared relatively less, and did not present so large a portion of the road problem as has been the case with many States subsequently taking up highway work where a great majority of the roads are earth roads, on which but small sums per mile have been spent. When the attention of various State highway commissions was turned to a study of the highway bridges, it seemed to be almost universally noted that a vast majority of the structures now in use were poorly designed; at least a vast majority of the structures have been found to be inadequate to modern traffic conditions. Compara- tively few structures have been erected under proper specifications and design. In a majority of instances no engineer whatever had been retained by the local authorities putting up the various structures. In general the most adverse conditions were imposed, and the limited funds have made necessary the erection of the least expensive bridge possible.

AMERICAN ROAD CONGRESS COMMONWEALTH OF VIRGINIA PROCLAMATION BY THE GOVERNOR GOOD ROADS WEEK WHEREAS, the AMERICAN ASSOCIATION FOR HIGHWAY IMPROVJE- MENT and affiliated organizations have elected to hold their jTiBBT ANNUAL ROAD CONGRESS in the city of Richmond, on November twentieth to twenty-third, nineteen hundred and eleven, for the purpose of bringing to the solution of the many difficult problems connected with the improvement of the public roads the combined knowledge and experience of the men who have devoted themselves to a study of this important question ; and WHEREAS, the President of the United States will be our honored guest and will address the Congress upon that important occasion; and WHEREAS, the improvement of the public roads throughout Vir- ginia, and their proper care and maintenance, will result in greatly increased prosperity and add immeasurably to the welfare of our people; THEREFORE, I, WILLIAM HODGES MANN, Governor of Virginia, do hereby earnestly request the people of this Commonwealth, and especially those charged with the management of our public roads, to attend and participate in the American Road Congress herein- before mentioned. I furthermore urge upon all civic organizations, public schools, churches, the press, and all other agencies within this Common- wealth that serve to promote human welfare to set apart the week beginning November thirteenth, nineteen hundred and eleven, which immediately precedes the Congress, as "GooD ROADS WEEK," and during that period to devote their united efforts to a furtherance of the movement for better roads, and particulary to the accomplish- ment of some practical result within the zone of their influence. 5 6 AMERICAN ROAD CONGRESS Given under my hand and the lesser seal of the Commonwealth at the Capitol, in Richmond, this first day of November, nineteen hundred and eleven, and in the one hundred and thirty-sixth year of the Commonwealth.

Russell Cecil, D.D. Address of Welcome by the Governor of Virginia. Address of Welcome by the Mayor of Richmond. Response by Logan Waller Page, President, American Associa- tion for Highway Improvement: On behalf of the American Association for Highway Improvement, the various affiliated organizations and the delegates participating in the holding of this American Road Congress, I desire to express our high appreciation of the courtesy and hospitality extended to us all by the people of this delightful city of Richmond and the grand old Commonwealth of Virginia. It is eminently fitting that we should assemble here, where early American history was made, to launch a great united movement, as important in an economic and industrial sense to the people of the United States as the great work of the master minds in statesmanship and war in laying the foundations of our government. One year ago, there assembled in the city of Washington a small body of men who were earnest in their conviction that the time had come when all of the agencies striving for the common cause of road improvement should work together, to the end that there should be no more playing at cross purposes; that the experience of each and every organization should be utilized as a guide to the work of each and every other organization, and that in the consideration of plans and policies which were too broad to be determined by any single State organization, there should be a way by which the interested parties could come together and consider them, and, finally, that 7 8 AMERICAN ROAD CONGRESS the entire movement for better roads should be so systematized and everywhere placed on so high a plane of honest and earnest effort that the cheap charlatanism of the professional promoter and the bungling efforts of the well-meaning but uninformed citizen should be no longer permitted. These were the conditions and the needs which prompted the formation of the American Association for Highway Improvement. Its organization was no reflection upon the good intent or the effici- ency of existing associations. In fact, it was the announced intention of the men who were responsible for the forming of this Association that this work should be done as far as possible through the organi- zations already existing. I venture the assertion that it would be necessary to travel far and wide to find a man who is deliberately opposed to road improve- ment. If it were only necessary to convince the people of the value of a good road, our labors would be superfluous. The difficulty begins when we attempt to convince the unprogressive man and the pessimist that a good road is so good that it is worth paying for, and we have still more difficulty before us when we endeavor to show him how he should go about obtaining a good road. Governor Sanders, of Louisiana, in addressing a road convention in his State, said that his people had wished for good roads, but they did not come; that they had prayed for good roads, and still they did not come; and finally, they had paid for good roads, and then they got them. It is necessary that a thorough campaign of education be conducted in every locality where the burden of bad roads hangs like a millstone about the necks of the people. The glory of the crusades have given to posterity the names of Richard the Lion Heart and Godfrey of Bouillon, but it was the lowly Peter the Hermit preaching at every cross road that fired the martial ardor of Christian Europe. In this campaign of education, three things are essential: first, that your work must have a definite object; second, that your plans must be practicable; and, third, that they must have intrinsic merit. In launching the American Association for Highway Improvement, we endeavored to fulfill these three requirements by the announce- ment of definite purposes easily capable of accomplishment, and con- taining such intrinsic merit that their general adoption would place road conditions in this country on a sound and economic basis. We hope that every organization affiliated with the Association will NATIONAL DAY 9 follow the same lines, adapting them to local conditions, thereby ren- dering the campaign uniform and nation-wide. These purposes are : "To correlate and harmonize the efforts of all existing organiza- tions working for road improvement. "To arouse and stimulate sentiment for road improvement. "To strive for wise, equitable and uniform road legislation in every State. "To aid in bringing about efficient road administration in the states and their subdivisions, involving the introduction of skilled supervision and the elimination of politics form the management of the public roads. "To seek continuous and systematic maintenance of all roads, the classification of all roads according to traffic requirements, pay- ment of road taxes in cash, and adoption of the principle of state aid and state supervision. "To advocate the correlation of all road construction so that the important roads of each county shall connect with those of the ad- joining counties and the important roads of each state shall connect with those of adjoining States." Officials of thirty State and inter-State organizations have now joined hands with the Association, and splendid support has been given to the work by the press, so that the great movement, which has reached its first year's culmination in this memorable Congress, has been made known to the public from coast to coast. I desire especially to make mention of the loyal and broad spirited support given this movement by the railroad companies. It is immaterial whether they are actuated by wise business foresight or whether they have the welfare of the people along the respective lines solely at heart : the fact remains that they are doing a work which benefits every man, woman atid child within the zone of their influence, and full credit should be given to them for it. The problems of road construction and maintenance will later on be dealt with in a most thorough manner by the leading highway engineers of this country, and it is scarcely within my province to go into a technical discussion at this time, but I shall not let the opportunity pass to say a word to you about what appears to me to be the most important subject in connection with the whole question of road improvement, namely, maintenance. The people in many counties are filled with enthusiasm for road improvement, and are hastening to spend enormous sums of money 10 AMERICAN ROAD CONGRESS in the construction of superb roads, and yet almost without excep- tion, they are making no provision to care for the roads after they are built. The same holds true with reference to road construction under many of our state highway departments. Right here in Virginia, your State highway commissioner is constantly urging and almost pleading for some provision looking to the maintenance of the fine roads which he has built and is building. To maintain the roads in good condition year after year requires a considerable annual outlay, but this outlay is infinitely less than the loss which must fall upon the people eventually if they allow their roads to go to utter ruin. Provide continuous, systematic maintenance and set aside every year an amount per mile estimated by the engineer in charge to be sufficient for the proper maintenance of the road, and you will follow a course which must make for economy and efficiency. Mr. Page here read the following: TELEGRAM FROM THE HONORABLE WILLIAM H. TAFT, PRESIDENT OF THE UNITED STATES THE WHITE HOUSE, Washington, D. C. November 19, 1911. L. W. PAGE, President American Association for Highway Improvement : I have had a cold for a week since I returned from my trip, and have spent the last forty-eight hours in the house, with the hope of being able, without risk, to go to Richmond tomorrow. I have been looking forward to taking part in the Good Roads convention with a great deal of pleasure, because I am in full sympathy with the move- ment that is gaining strength in every State and in the nation for the promotion of the construction of permanent good roads. The effect that they will have in increasing the value of farms, in making the lives of farmers and their families much more full of comfort, and in the general benefit conferred by greater ease of intercommunica- tion the country over, can not be exaggerated. I wish that I could be present to utter my word of approval and encouragement, but I feel that the trip as planned is one which would involve more risk than I ought to incur in my present condition. I have postponed this announcement until now, with the hope that I might avoid making it. The pleasure of receiving the hospitality of Richmond, which has GOOD ROADS AND THE FARMER 11 been mine at least twice, lingers long in my memory, and makes me deeply regretful that I must deny myself now the enjoyment of the trip. WM. H. TAFT. GOOD ROADS AND THE FARMER BY W. W. FINLEY President Southern Railway Company In considering the matter of highway improvement under the topic assigned to me "Good Roads and the Farmer" we are not taking a narrow view of the subject, for we are all directly and vitally interested in the development of agriculture in the United States. We must rely upon the farmer for by far the greater part of our food supply and for most of the materials for our clothing. We no longer have vast areas of unoccupied farm lands in the West. The constant growth of our cities and towns results in a steady increase in the demand for everything produced on the farm. This increased demand must be supplied, to a greater extent than ever before, by increasing the average production per acre and bringing under culti- vation or devoting to pasturage lands in our older States that are now lying idle. The problem of increasing the productiveness of our soils is being successfully solved by our progressive farmers, aided by the scientific experts of the United States Agricultural Depart- ment, the State departments of agriculture, and our agricultural colleges. There has been more real agricultural progress in the gen- eration in which we are living than in any other period of equal duration since the dawn of history. This is to the advantage of those of us who live in cities and towns as well as of the farmers, and our self-interest impels us to support every movement tending to economy in farm operations and to larger agricultural production, for it is only by these means that the profitableness of farm operations can be maintained and increased without, at the same time, unduly advanc- ing the prices which we must pay. Not the least important of the factors tending to bring about this condition will be improved country highways. They will directly and materially reduce the cost of haulage, enable farmers to market their products more advantageously, and, by adding to the attractiveness of country life, will tend to check the flow of population into the cities and towns and accelerate the movement " back to the farm. " 12 AMERICAN ROAD CONGRESS Bearing in mind our universal dependence upon the farmer and the importance of good country highways as a factor in agricultural devel- opment, I believe we should, at this time, look upon the road improve- ment problem as one primarily concerning the farmer. His interest should be recognized in the formulation of all plans for the construc- tion, maintenance, and regulation of the country highway. More especially this should apply to the selection of the roads which are to be first improved. We have in the United States about 2,200,000 miles of country highways of which only about 200,000 miles had been improved in 1909, the latest year for which complete figures are available, leaving approximately 2,000,000 miles unimproved. Hon. L. W. Page, direc- tor of the Office of Public Roads in the United States Department of Agriculture, and the honored president of the American Association for Highway Improvement, has kindly supplied me with detailed data as to the progress of road improvement in the counties traversed by the lines of the Southern Railway Company. His figures show that these counties contain a total of 176,725 miles of county roads. Of this total 10,321 miles, or 5.84 per cent, had been improved in 1904. In 1909, 15,298 miles or 8.65 per cent, had been improved. In 1904, the road expenditures in these counties amounted to $5,749,829. In the current calendar year, they will amount to approximately $1 1,500,- 000. Assuming that the mileage improved since 1909 has been as great as that improved from 1904 to 1909, there are still about 150,000 miles of unimproved country roads in those counties. Similar condi- tions are found in many other parts of the United States, and it is obvious that the task before us is so great that all of the unimproved roads can not be improved at once. Each community must decide which of its roads shall have attention first. Broadly speaking, country highways may be divided into two gen- eral classes those which may be denominated trunk lines, running for long distances and connecting the cities and towns along their routes, and those which radiate from a market town or shipping station. The first of these classes the trunk line highways, afford ideal routes for tourists. There are some localities especially those most fre- quented by tourists, where the construction of trunk line highways of this class is highly desirable and their improvement necessarily benefits the farmers adjacent to them. At the risk, however, of seem- ing to be actuated by the interest of the railways, I have no hesitation in saying that, if the greatest good is to be done to the greatest numbers, GOOD ROADS AND THE FARMER 13 the farmer is more interested in the improvement of the roads of the second class which I have mentioned those radiating from a market town or shipping station. By giving attention, first, to those parts of these roads immediately adjacent to the towns and shipping stations and extending improvements out into the country year after year as funds may become available, entire regions will, in time, be traversed by networks of good roads. Then, by connecting up adjoining sys- tems of these radiating roads, trunk lines and through roads for tourists will ultimately be formed. The improvement of these radiating roads will be beneficial not only to the farmer, but also to a large proportion of the dwellers in cities and towns. They will enlarge the trade of retail merchants, facilitate the work of rural mail carriers and extend the limits within which local newspapers can be circulated on the day of publication. Manufacturers and users of automobiles have given a great impetus to the movement for the improvement of the country highways of the United States. By devoting their time and money to this work, they have earned the gratitude of the American people, and I believe that, in considering plans for road improvement, their interests should be considered, as well as the paramount interests of the farmers. There has been for years an increasing demand for these vehicles from residents of cities who use them for pleasure and business. The extent to which this has grown is shown by statistics compiled by the United States Census Bureau for the year 1909, showing that in that year a total of 127,289 automobiles, valued at $165,115,100, were manufactured, as compared with 22,830, valued at $24,630,400, in 1904, an increase of 485 per cent, in the annual number manufactured in five years, while in the same period there was a decrease of 12 per cent, in the number of carriages manufactured in the United States. It may be that, in view of the large extent to which passenger auto- mobiles are now used in cities and towns, a large proportion of the demand in this field in the near future will be for replacement and for improved models. We find many of the manufacturers now giving increased attention to the development of efficient motor trucks, wagons, fire engines, ambulances, and patrol wagons, and these vehi- cles are rapidly displacing those drawn by horses in our city streets. Motor vehicles and traction engines are already used to a consider- able extent by farmers in some localities. Looking back over the comparatively few years since the establishment of the industry and noting the improvement that have been made in the motors and the 14 AMERICAN ROAD CONGRESS large numbers of special designs of vehicles that have been produced we may feel sure that the manufacturers will meet the growing demand of the farmers by supplying whatever special types may be required. As an illustration of the way in which practical farmers are looking at this matter, I may mention that, within the past week, a man who contemplates buying a large farm in a region traversed by the South- ern Railway told a representative of our company that he was con- templating a location about fifteen miles back from a railway station. He said that the distance made no difference to him as the road was good and he proposed to do all of his hauling with a motor truck. What this farmer proposes to do will be done by many other farmers as the country highways are improved, and I have no doubt that the annual addition to our good roads mileage will result in corresponding increases in the agricultural use of motor vehicles. Therefore, I do not believe that in advocating the improvement of radiating roads rather than of trunk line highways, I am opposing the ultimate interests of the users and manufacturers of motor vehicles. In fact, I believe that, in the near future, the manufacturers must look to our farmers for their largest opportunity for the extension of their sales. Others who will address this cbngress are better qualified than I to give advice as to the types of good roads to be constructed and as to the best methods of road maintenance and management. I cannot refrain from saying, however that I believe that every one here who has seen the beautiful tree-lined roads of France will agree with me as to the desirability of planting trees by the roadside wherever this can be done without being disadvantageous. I know that a tree shading the ordinary dirt road is detrimental, as it retards the drying up of the mud after severe rain storms. I am advised, however, that shade is not detrimental to a macadam road, but is beneficial to it, and all of us who have traveled over our country roads in the heat of midsummer can realize how grateful to both man and beast would be a row of shade trees on each side of the road. I believe, Mr. Chairman, that the difficulties in the way of highway improvement in the United States sometimes seem to be greater than they really are. When we look at the work in its nation-wide entirety and think of our 2,000,000 miles of unimproved roads, the task ahead of us seems to be so great as to be almost impossible of accomplish- ment, but the good roads problem while it is national in a sense, can be solved only by the solution of the vast number of local problems GOOD ROADS AND THE FARMER 15 which go to make it up. The immense task involved in dealing with 2,000,000 miles of roads resolves itself into a large number of rela- tively small tasks, no one of which is impossible of accomplishment. The total highway mileage classed as unimproved includes, of course, a large number of roads which are so little used that their improvement can be postponed almost indefinitely. It includes other roads which can be maintained in a passable condition at relatively little cost and on which there is no immediate necessity for making expensive improvements. Taking these conditions into consideration and begin- ning first with the radiating roads to which I have referred, I believe that it will be possible for us, within relatively a few years, to have a system of improved country highways in the United States which will be of almost incalculable benefit to our farmers, and that we shall all share from the advantages of the higher agricultural development which will follow. Within the past few years a large amount of educational work as to the advantages of good roads has been carried on in the United States. This has been participated in by the Good Roads Office of the United States Department of Agriculture, by the several States, the newspapers and the railways. The railway company which I have the honor to represent has contributed to this educational cam- paign by the running of good roads trains over its lines, by the distribu- tion of literature, by encouraging the organization of good roads associations in the territory which it traverses. As a result of this work it is no longer necessary to talk to the American people about the advantages of good roads. What is now needed is to direct the public sentiment in favor of their construction along the most intelli- gent lines by supplying helpful advice and information. This is one of the objects of the American Association for Highway Improvement, under the auspices of which this Congress is being held. We can all contribute to this work, each in accordance with his opportunities, and I believe that by doing so we will perform a high public service of benefit primarily to the farmer and, in the end, to all of our people. 16 AMERICAN ROAD CONGRESS GOOD ROADS AND WATERWAYS J. HAMPTON MOORE Member of Congress from Pennsylvania and President of the Atlantic Deeper Waterways Association Good roads, like good waterways, are essential to the country's development. They assist in the creation of our national wealth, and afford a means of distributing it. In a commercial sense they are fairly comparable to the circulation of blood through the arteries and veins of the human system. I am an advocate of the prompt and comprehensive development of the inland waterways of the United States, particularly those so long neglected along the Atlantic Coast, but I am none the less a be- liever in the importance of improving the earthen roads of the country in order that they may meet the requirements of modern business and the increasing transportation demands of our 90,000,000 of popu- lation. As with our inland waterways, so, unfortunately, with our American highways, we lag behind our European brethren, notably of Germany, France and England still wasteful, still hair-splitting, still dilly- dallying, still running our vessels against the shoals, still taking the dust of the fellow who gets the road ahead of us, still leaving to the next generation the advantages we ought to receive for ourselves. THE WORK OF AGITATION I am glad the American Association for Highway Improvement has been formed. If it adds a single new road to the assets of a progres- sive and long-suffering people; if it helps to carry transportation facilities to any section of the country not hitherto penetrated by modern avenues of communication; if it succeeds in crystallizing into one grand forward movement the sentiment of diversified associations working for the same end, then indeed it will have served a good purpose. Or if, in the laudable work of agitation, it shall succeed in creating a better understanding of our transportation needs, then likewise will it justify the efforts of its founders. For as it has been with water- ways, so it is with highways. We have been indifferent; we have fallen behind; we have devoted our time to other enterprises; and if we are not to be eternally hardened to our imperfections and incon- veniences, we must have recourse to agitation, and that persistently, GOOD ROADS AND WATERWAYS 17 to recover lost ground. And that valuable ground has been lost is amply proven from day to day by the insistent demands of the power boat and the motor vehicle, with their manifold accessories to trade and commerce. HELPING OTHERS FORGETTING OURSELVES We have been waiting a long time for these improvements. The interior of our great country possesses 50,000 miles of water ways, only half of which are navigable. Trails of the pioneers still pursue their course through rugged mountain passes, and some of them are little better now than they were in the days of the flint-lock and the trapper. For more than two-hundred years we have waited for a canal through Cape Cod. The storms of the present month (November) have carried additional lives and property to destruction upon this cape, but there is no relief. They are civilized people who boast of their progress in New England, but they have stood submissively for 1000 disasters upon Cape Cod during the past twenty-five years alone. They will build canals at Panama, and expend the nation's resources for the uplift of the Cuban and the Filippino, but the wreck- age at Cape Cod goes on unchecked. In the area of the Chesapeake and Delaware we have more commerce in one year than will be done through the Panama Canal in ten years, and yet since 1829 we have been content to do business on a 13-mile canal drawing 9 feet of water, or risk our lives and property on a 325-mile course at sea. We have made substantial progress, but we have been confronted with delays and obstacles that have lingered only because we have never effectively united to remove them. PLANS OF OUR FOREFATHERS It is doubtful if our forefathers would have been so patient as we have been. They were planners and they had progressive ideas, albeit they were also addicted to the "red tape" habit, which still prevails to an aggravating extent. Back under the Jefferson admin- istration the people demanded transportation facilities to the great new West, and in 1806 the construction of the Cumberland Road was authorized by Congress. The history of the Cumberland Road is a story of hesitations and disappointments. It was to have been a great national highway such as is now sometimes proposed to link the oceans, across the continent. Its construction proceeded 18 AMERICAN EOAD CONGRESS until 1822, and then the President (Monroe) decided that the Con- stitution interfered with further appropriations for its maintenance But the earlier statesmen pressed forward with other projects, very largely through the separate States, and were especially active in the construction of highways and canals. For a quarter of a century after George Washington, roads and canals, and internal matters generally, were the chief thought of the national leaders. The messages of all the earlier Presidents breathed a desire for the peaceful occupation of new country and the dissemination and increase of our national wealth. All this they hoped to accomplish through good roads and good waterways, for railroads at that early day were creatures only of the imagination. Canal construction was one of the chief concerns of public men, both before and after the completion of the Erie Canal, and continued the subject of agitation and legislation until the advent of the railroad, along about the '30s. THE ERA OF THE RAILROAD If we have fallen short of the expectations of our ancestors in road or canal building, and have lost anything of their energy in this regard, it was doubtless due to the appearance of the "iron horse." Men who had money to invest took it from the canals and put it into railroads. Those who sought to open new fields of industry, or to enter rich and undeveloped territory, applied their efforts to the construction of railroads. The government of the United States also entered heartily into the work of railroad construction, and assisted materially, both by grants of land and the expenditure of money, in the completion of vast systems. Those who quibble today about the right of the govern- ment to aid in the construction of highways, or to improve and sustain waterways, will find embarrassing precedents in the history of railroad building in the United States. It is fair indeed that our memories should be refreshed upon this interesting phase of our national prog- ress. And if the government of the United States could aid in the building of railroads, or can build a canal at Panama, or financially assist in the uplift of a foreign people, why, in all fairness, need it hesitate to put new life and vigor into the commerce and trade of the American people themselves? GOOD ROADS AND WATERWAYS 19 COMMERCE LIMITED BY TRANSPORTATION No one with common sense will seek to curtail the advantages which the railroads of the country afford to the people. Whether they are rightly or wrongfully managed is beside the question. Whether they seek to control the political powers, or exercise undue influence with the legislatures, need not now be considered. The railroads are useful; they serve a great and noble purpose, and they serve it better in the United States than in any other country in the world. They have aided vastly in the development of the country. But it is noticeable, and cannot be disputed, that, in the great national movement for the extension of railroads, our waterways and our high- ways have been subordinated to their influence and operation, until the value and availability of both systems has been impaierd. It may not have been the intention to destroy the roads and the water- ways, but that they have been " overlooked," in the general advance, is at least a charitable way of stating the facts. It is now evident that we need them both, and that, if we are not to maintain a monopoly in transportation, and leave the common carrying business solely with the railroad, we must have improved waterways and a modern system of earthen roads. ZENITH OF RAILROAD CAPACITY Before proceeding further, let us recall the commercial distress that followed the car shortage of 1907. The railroads were then in the zenith of their power and capabilites. Were they able to carry the freight which the wealth producers of the country had created? In the language of Mr. James J. Hill, the best quoted magnate of them all, they were not, for in an address made in Washington, at the National Rivers and Harbors Congress, Mr. Hill declared for a deeper Missis- sippi as a relief to railroad transportation. And this phase of the problem was also clearly presented in an address by Mr. John F. Stevens, of Panama Canal fame, then vice-president of the New York, New Haven and Hartford Railroad, at the Baltimore Conven- tion of the Atlantic Deeper Waterways Association in 1908. I quote what he said : It must be remembered that within sixty years about one hardy business lifetime our railway main lines have risen from nothing to 225,000 miles, over which traffic, both freight and passenger, is carried at speeds equal to, and at rates, generally speaking, lower, than in other countries, where the cost of 20 AMERICAN ROAD CONGRESS labor and material is much less than with us, and where density of tonnage is far greater. But a time has now come has been with us for some years when the railways, considered as a unit, are not capable of handling satisfactorily the interchange business of the country, even supplemented as they are to a certain extent by water lines. And to such lines they should bear the relation of allies, instead of opponents, if they now do not. WASTE LAND AWAITING CULTIVATION In the light of these statements, which are confirmed by many of the far-seeing railroad men of the country, we have a right to ask that commerce be fortified against any possible future congestion. There are but two methods of relief. Aerial navigation may some day make a third but the wealth producers of the land today have actual need for the earthen roads and the waterways, and these should be public thoroughfares in the strictest sense. For if we do not have these means of communication, and must still depend upon the railroad, which either will not or cannot further extend its lines, when are we to develop the areas of waste land where agriculture is feasible and no outlet is provided? Speaking as of the Atlantic Coast, I venture to say that the more than 35,000,000 of population from Maine to Florida would be living better, and at less expense, if we were able to open up and cultivate our own neglected fertile lands east of the Appalachian Chain. The Eastern farmer need not go West. We can now sell farm lands in New England as low as they can be purchased in Iowa. Within 50 miles of Philadelphia we can sell them at from $60 to $100 an acre. In New Jersey and Pennsyl- vania there is ample opportunity for the farmer who is willing to apply himself to his trade. Delaware, Maryland and Virginia are holding out inducements to the agriculturist, and North Carolina along the coast line is rich and almost virgin country. In South Carolina and in Georgia there is plenty of room for those who want to till the soil but in every instance the farmer's problem is largely one of trans- portation. FARMS WITHOUT A MARKET The farmer must get his crops to market. How often does it happen that the land he would like to occupy is too remote with respect to transportation? Does the railroad go to the farmer of Florida? This very year his crops have been rotting in some pro- ductive areas because he has no outlet to the North. In the water- ways movement we are demanding that the streams be opened up GOOD ROADS AND WATERWAYS 21 to the farmer. If the railroad does not go to him and there are no adequate roads or waterways, the country roundabout must go to waste. Give the producer a chance to get in and out, whether the railroad comes to him or not, and you will help to keep the farmer contented, as you will afford him lucrative means of employment. The same reasoning applies to the South, to the great Northwest, and to that bounding " Middle West," which has been advancing so rapidly in recent years. If better transportation by road or water will add to the productiveness and profit of farming, there will be less of unrest, and a truer and more genuine spirit of patriotism. BE RIGHT, BUT GET A START Another thought: Perhaps it is better to be right than to go ahead. Unquestionably we should proceed as the Constitution and the laws direct, but when are we to proceed? Has the Cumberland Road been finished? Has the canal at Cape Cod been cut through? Are we still to rely upon the Oregon Trail for our journeys into the North- west? The government was asked to aid in the construction of the Erie Canal in 1811. There were too many halting States to permit the government to proceed. New York was game. It proceeded alone. It constructed the Erie Canal, and became the Empire Common- wealth. Moreover, it earned the gratitude of the nation. And all this it did before a single railroad track was laid in the country. Now we have steam and electricity. The automobile and motor boat have made their appearance, and 30,000,000 horses are still to be counted in our animal population. If the Constitution which impelled Mon- roe to check the progress of the Cumberland Road is still unamended, neither have the separate States been brought into thorough working accord upon a comprehensive plan of road construction. Here is work for the Association. If results are to be obtained, the agitation must continue. It must be carried forward to the National Congress, and it must be taken into the legislatures of the States. But a definite plan is needed, whether it looks to federal initiative, absolute State control, or federal supervision with the cooperation of the States. There must be a definite and reasonable plan. INFLUENCE OF AUTOMOBILE AND MOTOR BOAT Neither our forefathers, who planned extensive internal develop- ments, nor the railroad builders whose marvelous advance dwarfed 22 AMERICAN ROAD CONGRESS the country roads and waterways, were able to divine the modern forces which now cry out for recognition. But they have come! The automobile is here, and the motor boat is here. The automobile has enlisted the expenditure of hundreds of millions of dollars, and the motor boat has increased to hundreds of thousands in number. On road and river bank, establishments are being built for the con- struction and distribution of these new and useful instruments of transportation, and around them new settlements of busy work- men cluster. They are growing more and more in popular favor, adding to our business opportunities, and holding fast to worthy employment, our skilled mechanics. They have come to stay; and roads and waterways to accommodate them must be provided! It is all so plainly evident that "he who runs may read. " And as they grow and expand in the world of commerce, these new factors in internal development will neither harass nor destroy existing methods of transportation, but, on the contrary, will make new trade for railroads, as well as for all the common carriers whose terminals and connecting lines will permit of an interchange of business. For what ship may come in from the Orient or the Occident and yet not yield a portion of its cargo to the common carrier of the United States? Or what coastwise vessel, or inland barge, penetrating new or hitherto neglected territory, that will not land its quota of business for existing transportation lines? Or what vehicle of the road, be it Conestoga wagon, or horseless truck, that comes and goes where railroads do not serve, that willl not likewise add to the sum of our national wealth, and incidentally increase the work of our common carriers? The answer is short and decisive: it is, "New business for everybody." GET SOMETHING STARTED! That this country, still capable of great internal development, shall be limited in its progress to the carrying capacity of the railroad is an untenable proposition. We have passed beyond that. Our productive power requires new and auxiliary means of transporta- tion, and we should have them. Our opportunities to create new business for capital, and to provide employment for labor, should not in any particular be restricted or curtailed. We must have good roads and connected waterways, and we must agitate until they come. The several States are awakening to public sentiment in this regard, and gradually the national government is being impressed. Already GOOD ROADS AND WATERWAYS 23 the nose of the camel has entered Congress. At the last regular session, an appropriation of $2,000,000 was made for a memorial to Abraham Lincoln. The form of memorial was left to a commission, but senti- ment has been crystallizing in favor of a road from Gettysburg to Washington, which would establish a memorial more lasting than bronze and more serviceable to the plain people, whom Lincoln loved, than any creation of the artist or the sculptor. Whether the commmission will yield to popular sentiment, and construct a road that will be at once a memorial, and a blessing to mankind, remains to be seen. In this instance there need be no constitutional question, nor any concern as to the consent of the States. The construction of a Lincoln memorial highway would be a work of utility which the people would applaud. FROM GETTYSBURG TO RICHMOND And if the nose of the camel, thus injected into Congress, should be accepted as expressing the will of the people, it might with propriety be pushed a little further, so that the great Lincoln highway shall continue to the city of Richmond. The roads of the Romans were the admiration of the world. The roads of France and of England are the pride of Europe. We have natural God-given wonders in America which excite the interest of our foreign visitors. But the permanent works of man have not yet reached perfection in America. Let us have an American Appian Way! From Gettysburg to Rich- mond is not an idle dream. Pennsylvania, Maryland, Virginia and the nation's Capital ! It is a plausible and glorious possibility. The soil of Rome is not more sacred than the fertile fields that mark the gallantry of American soldiery under Grant and Lee. The pages of history produce no names that future ages will hold in greater rever- ence than those who fought on either side in that great struggle. Then why not construct the Memorial here? Why not make this the beginning of a comprehensive plan? It would seem to be the golden opportunity, the one great chance to hold the interest of the people of all the States, and to cement their good will and cooperative power. It would serve the practical purpose of providing an object lesson for future operations in road construction, and it would tend, as no other memorial could, to develop that spirit which inspired Lincoln at Gettysburg to proclaim a reunion "of the people, by the people and for the people" that " shall not perish from the earth." 24 AMERICAN ROAD CONGRESS THE ROAD THROUGH DELAWARE GENERAL T. COLEMAN DU PONT At the request of Mr. Page, I am going to tell the convention a little about "my hobby," the new road I am building in Delaware, and the results I hope for when it is completed. My object in building the road is not only to provide a good high- way where it is badly needed and where it would run through a splendid farming section if developed and cared for, but to work out in a prac- tical way a problem that will, if successful (and I feel sure it will be), revolutionize the building of roads in the United States. The problem is "How can a free country road be built and made to pay its original cost, cost of maintenance and a fair return on the money invested. After outlining briefly my plans for the road now being constructed in Delaware, I will explain the plan I have been working on for some- time past, believing it will be of greater interest than the Delaware undertaking because it is not local but a proposition in which all are interested. The land acquired in Delaware will be 200 feet wide except through cities and towns where a width of 120 feet will be accepted. In building this road several materials will be used, but generally speaking, the material most available in that section will be used for making a foundation or base of concrete 5 inches deep, and on this will be built 2 to 3 inches of trap rock, or local gravel, and asphalt, thus making a first class, up-to-date road. My intention is to make a proposition to the State to maintain the road for a period of 5, 10, 15, or even 20 years at a cost that will be less than the cost of interest on the bonds, had the State issued the bonds and built the road. My object being principally to insure the road being kept up and to show the exact cost. Such figures are hard to get at from the public records, but will be available for all interested in good roads, should I make this arrangement with the State. My idea is to keep this road as dry as possible, and arrangements will be made with the farmers along the line of the road to clean off the snow. As soon as a storm begins a certain number of farmers will start with power sweepers. These men will be relieved at short intervals, until the snow has stopped falling and the road is clear. In this way one of the greatest foes of a road will be handled. THE ROAD THROUGH DELAWARE 25 A plan for taking care of repairs and of keeping up the road has also been worked out. Every part of the road will be gone over every other day by a road man and repairs commenced the day the road is finished, if they are needed. Not a depression nor an upheaval of one inch will be allowed to go uncared for. Ultimately, I hope the road in Delaware will require the whole 200 feet for public use, having in the center a strip 40 feet wide for high speed vehicles. On each side of this, say 15 feet should be reserved for electric car lines, then 30 feet outside the electric line for vehicles, each side for travel in one direction only. On both sides and beyond these "metal" roads, will be say 15 feet of dirt roads under which will be laid all pipes, condiuts, sewers, etc., thus avoiding tearing up the " metal" road. Beyond these dirt roads will be cement side- walks, grass and trees, or shrubbery; but to build in this way at this time would be folly, as some places where the road now runs, traffic only averages seven vehicles a day. The day is coming when speed laws will be a thing of the past and automobiles will make 60, 80, yes 100 miles an hour on our roads carrying men to and from their daily work, thus bringing healthy country life within reach of many of our citizens. Flying machines have come to stay, and suitable places where they can land and from which they may start will be arranged for, and this I intend to make one of the features of the road through Delaware. I hope this road will greatly improve conditions in lower Delaware by bringing modern improvements within reach of many people now cut off from them. It was with this idea in my mind in an undeveloped condition that I asked for a right of way 200 feet wide, or rather the right to acquire 200 feet. In a very few years, I will have figures to show what the result will be; as if the method suggested proves practical, it will work out in the case of the road through Delaware. However, in my case, the land is acquired from only a few, which is not entirely fair, since others who are deprived of no land will be equally benefited by the road and improvements that follow. In the Delaware road I am going to utilize the extra land acquired not occupied by the road in several ways : First, to do anything that will tend to develop Delaware. Second, to make it easy by offering inducements for any one want- ing to build a trolley line to do so. 26 AMERICAN ROAD CONGRESS Third, to establish at certain intervals places for the landing of aeroplanes of all kinds. Fourth, stations for gasoline and other supplies and for repairs to vehicles, and anything needed to aid any traveler on his way. My plan is to put the stations in the farming districts in charge of a graduate of an agricultural school, who each year will put in certain crops in the most scientific manner and who will tell the farmers as far as possible the kind of crops to plant in certain lands and who will analyze the soil and find out what kind of fertilizer is most needed for the coming crop in any particular field or what crop is best in certain soil, to maintain a place for the grangers to meet, to keep in touch with the Agricultural Department at Washington and take advantage of its knowledge, to show by actual practice plowing and cultivaton by machinery as against horse power, and other new methods of farming. This should bring the farmers into cooperative work, for example, there are four farms adjoining, today, each one put in say 80 acres of wheat in four different fields of 80 acres each. Let them take down the fences and with a steam or gasoline engine the four could put in 320 acres of wheat at less than the labor cost, including the wear and tear on the machine, than it costs them to put in 80 acres by the pres- ent accepted method in Delaware. This economy of cooperation is equally applicable in the harvest season, with improved machinery. In the case of this road, as it is my intention to develop the State, the income will be used to maintain these various stations and not for maintaining the road, the comparison is not an exact one, but the figures will be available and can be compared with the cost of mainten- ance and applied to other cases so others interested may have the ad- vantage of them. The good road movement in the United States is now being taken up everywhere and by all classes of people, but legislatures are slow to pass appropriations, fearing to raise the taxes of their constituents thereby making themselves unpopular. Of the farmers, "The greatest users of roads, " only a few are able to see that in being satis- fied with the present condition of our roads they are in reality paying higher road taxes than they imagine. In order to "haul" their produce to the markets and to "haul" fertilizers and other necessities to their farms they keep from two to four times as many horses or mules as are necessary, and frequently keep extra men to do the work caused by inferior roads. THE ROAD THROUGH DELAWARE 27 From a number of figures compiled from different sources, the average load drawn by two horses or mules on our unimproved roads is about 960 pounds, and the average distance from farm to market, 12 miles. The average day's work for two horses is 12 miles a day on these roads. On the French roads, for comparison, one horse takes a load of 3000 pounds 18 miles every day in the year. If our farmers would count as road tax, the extra amount they pay to maintain horses men, wagons, and harness to make up the difference between what they now haul and what they would haul on a good road, they would refuse to vote for any representative or senator for the State legislature, who would not promise to reduce their expenses by voting for liberal appropriation for good roads, for the absolute maintenance of them at all times, or in case of the plan hereinafter described, vote to loan the credit of the State for such time as may be required. I was much surprised a few weeks ago in talking to a man at the head of a department having charge of many miles of roads, to hear him say "after a road was built properly, it required absolutely no expense for maintenance for three or four years." This remark points to one of the greatest mistakes in regard to American roads, for in many of our states roads are built with absolutely no provision for their up-keep, the consequence being after a few years they are really worse than the original dirt road and cost about as much to repair as to build a new road. One could go on indefinitely in the above strain, volumes have been written on the subject, but what the American people want is a way to build roads economically and quickly without a greatly increased tax on their resources. Now for the problem "How can a free country road be built and made to pay its original cost, cost of maintenance and a fair return on the money invested?" The following plan, I believe, could be adopted successfully in most of the United States, east of the Mississippi River and in a good many places west of it, in fact wherever the population is a producing one. This plan would provide funds for building the road, maintaining it, and subsequently repaying to the State or corporation building it, all the interest and principal and a good return on the investment. When this is done there will be left a tangible surplus, the disposal of which will be suggested later. Assuming that each State has passed the necessary legislation and provided the proper organization or commission to carry out its pur- 28 AMERICAN ROAD CONGRESS pose, then suppose a road is wanted between two towns, say 15 miles apart. This would be ascertained by submitting the question to a vote of the people owning the land, one vote for each acre owned, say five miles each side of the suggested route. The route should be as nearly straight as possible. The vote should be by acres. If a majority of the land owners (in acreage) vote in favor of the road, the fact of the favorable vote would automatically constitute the right to build the road. Land could be condemned if necesssary, and the road laid out, say 250 feet wide. The people on the line of road would give all the land, namely, 250 feet, but the ratio between the benefits that would accrue to the donors would be equalized as follows: Those within one mile would contribute only 30 per cent of the land, the owners of land between one mile and two mile 25 per cent; two and three miles 20 per cent; three and four 15 per cent, between four and five 10 per cent of the 250 feet, total 100 per cent. While those whose land the road passed through would give 100 per cent, they would be repaid 70 per cent, the next one would be repaid by the next 75 per cent, the next 80 per cent, etc., this adjustment having been made by a commission. The act authorizing the building of the road would carry the power to adjust, condemn, and all other power required by a commission elected or appointed for the purpose. Inasmuch as the person whose land is taken at today's price and paid for at the value the day he is paid, the division above may not be necessary, because being repaid for his land at the advance price likely to follow the devel- opment would be enough of an inducement for him to give up the use of the land until such a time as he was paid for it; but should it deprive the owner of too much land, the division into 30, 25, 20, 15, and 10 per cent is suggested. Then bonds, guaranteed by the State, both principal and interest would be issued on this 250 feet and the pro- ceeds used for building the road, and paying carrying charges. The entrances to properties should be 150 to 200 feet apart or the dis- tance between streets and alleys in the nearest town. The road would be built at first say 20 feet wide, than 30, then 40, then 50 as the growth of the section warranted. As the country grew and developed, the strip on either side of the road would become more valuable for every purpose, trolley lines, telegraph, telephone, sewers, rights of way in and out of adjoining properties, etc. The income from that part of the land not needed for road purposes until such a time as required for public service, such as telephone, telegraph, trolley lines, and other public utilities which would pay a THE ROAD THROUGH DELAWARE 29 rental in proportion to their earnings, would be used, first, for main- taining the road in an absolutely perfect condition. For this the State might have to make the road building commission a temporary loan. The period of not being self-sustaining passed, the income would be applied (after maintenance), to interest, then to paying off the bonds issued for construction. After the bonds are paid the income will be applied to paying for the land acquired at its value the day it is paid for by the road commission. After this, toward paying county and State debts, etc., or the returns can be distributed to the share- holders who gave land as their interest may appear, but this income, should it go to the land owner, should be bought and sold with the land just as a spring of well known water goes with the land. That is, selling the land would pass title to the stock or the excess could be used for extending the road. One suggestion would be that when the income reached a point when every one was paid in full, the property could be made to pay less interest, by turning part of the earnings strips into boulevards and drives for beautifying the cities through which it runs. This is probably the best solution, but what- ever the soltuion it should be broad enough to allow building chari- table institutions, more roads, or for any other use that seems best at the time, or even follow the example of the Delaware road and estab- lish stations for bringing before farmers and others the latest known methods as applied to agriculture. There would be about 26 acres per mile of land for various uses. This should rent at from $5 to $10 per acre from the first for agricul- tural purposes, and create an income of from $130 to $260 per mile, which would easily maintain the road the first few years. At the start the State might have to pay part of the interest, but as the town grew, and the country developed the rental for this 100 feet on either side would soon advance to a point where the income would be ample for maintenance and interest, and after that the bonds could be taken care of. If any of those present will look back twenty five years and note the value of land along an important road at the edge of the city, or even in the city now, as compared with that same value twenty-five years ago, it will at once be apparent that the income would soon be a valu- able asset to the State, county or to the builders of the road. Suppose this idea had been put into effect when Broadway, New York, stopped at Canal Street. What would the income (ground rent) from 100 feet each side of Broadway from Canal Street to Yonkers be? In some 30 AMERICAN ROAD CONGRESS places the income would exceed $1,000,000 per mile. Aroad built under these plans would be maintained in perfect condition always by this income, it would be a good road, the land along it more valuable, more desirable, and therfore bringing in sooner than usual, returns worthy of most careful consideration, always keeping in mind that the road must be in perfect condition with penalty for neglect. This is important. To refer again to the income from the land along side of the road, where the value of the land is likely to increase rapidly, it might be well to issue more bonds in the first place and pay for the land then and there so that when the road became self-sustaining and the income was increasing rapidly a block that had large earning power could be followed by a block which would be a park and on the line of this road the commissioners might alternate a paying block and a park, depend- ing entirely upon the earning power of the land along side, but I believe the income spent in this way would in the long run be better than to pay dividends to contributing land owners. However, in each section of the country this problem would have to be treated by the desire of the people in that section. This plan is one that will require a good deal of thought and to put it in more detail would, I am afraid, tend to confuse rather than en- lighten my audience, but this will be followed in the near future by figures given from the results of the experiment in Delaware. HIGHWAY ENGINEERS' AND CONTRACTORS' DAY November 21, 1911 HAROLD PARKER, Chairman Former Chairman Massachusetts State Highway Commission MR. PARKER: Gentlemen, the arduous duty of presiding at this meeting has been thrust upon me, and also the duty of making a speech. Mr. Page has laid out a certain amount of work to be done which will take at the lowest figures two hundred minutes, and the time allowed is about one hundred and fifty minutes, and this is not count- ing my speech as taking up any time at all. So I am going to cut my speech out entirely, and simply say that I have just come from the meeting in Rochester, New York, where we had a very large assem- blage of road-makers; at that meeting a formal resolution was passed sending the good-will of that convention to this, through Mr. Page as president, with the sincere hope that not only would this convention be successful in every respect, but that the life and vitality of this Association should be perpetuated. So I, representing that Association, and at the present time its president, want you to understand me as saying that the two Associations should go hand in hand, that so far from being rivals, they should be the closest friends; and I, speaking for them and the directors of that Association, want you all to appreciate that that is our view, and not only our view in our own minds, but as expressed publicly and by authority of that convention. This morning we have a series of papers which are to be discussed by certain gentlemen, whom I shall take the liberty of calling upon from the audience, and I want to say that it is neceassry for us to abide by the time limitations. The papers will occupy ten minutes or less, and the discussions twenty minutes more, divided into speeches of five minutes each, and if I interrupt any of you in a very interesting passage, you will take it not as a personal assault, but simply as the fulfillment of my duty. 31 32 AMERICAN ROAD CONGRESS The first one to address us today is Mr. McLean, of Toronto, who is the provincial engineer of Ontario, Canada, a man I have known for years and whose standing there as well as in this country, is known to everybody interested in this question. STONE AND GRAVEL ROADS W. A. MCLEAN, C.E. Provincial Engineer of Highways for Ontario, Canada An ideal roadmaking material, possessing every desirable quality under all conditions, for service, durability and cost, continues to be used in Utopia, but as far as we can learn, in no other country. That such a material exists, it is well to dream, but in more practical inter- vals it is not the part of wisdom to give up doing the things we can do because we want to do something we cannot do. Motor traffic has led to an important use of bituminous binders on main roads; but water-bound broken stone, substantially as advocated by Tres- aguet, Telford and Macadam, is still the mainstay of roadbuilding, while gravel is its useful ally. CLASSIFICATION There is a tendency to think of the trunk roads, the interurban roads, the roads of through traffic, as the all important phase of the road problem. Without minimizing the usefulness of splendidly built main roads, it is only just to say that all roads are important, and that all deserve a type of construction and system of maintenance in keeping with the amount of traffic over them. In a consideration of construc- tion, the classification of roads is a logical step, and while under any classification, one grade will merge into another, at the arbitrary dividing line, yet in every country of good roads, a classification is necessarily adopted. In Ontario, Canada, the roads are estimated to be 50,000 miles in total length. Careful consideration has shown that in view of local conditions, these might be classified approximately as follows: Class 1. Inter-urban and trunk roads, 5 per cent. Class 2. County or leading market roads, 15 per cent. Class 3. (a) Main township roads, 50 per cent; (b) Secondary township roads, 30 per cent. STONE AND GRAVEL ROADS 33 In the foregoing classification, class No. 1, inter-urban and trunk roads, includes such highways as would comprise a State or provin- cial system, and of which, because of heavy, constant through traffic, the proper construction and maintenance is an unfair charge upon local municipalities. These roads, are of the type which should be built in the most permanent manner, using Telford or other suitable foundation, and a strong broken-stone covering with bituminous binder. Class No. 2 comprises the main arteries radiating from local market centers, and over which might ordinarily pass from 50 to 150 vehicles a day. Such roads we believe, should have a broken stone covering of the macadam type, and if subjected to sufficient motor traffic, should be oiled to preserve them, and save adjoining property from injury. For heavily travelled suburban roads, adjacent to large cities, the type of construction may be that belonging to Class No. 1. Class No. 3 (a) comprises the concession or other roads of a town- ship, on which numerous farms front, and which converge into and create the traffic of the county roads of Class No. 2. On such roads there may pass from 5 to 50 vehicles a day. The more important of these deserve to be metalled with broken stone, if good gravel or other suitable material is not available. Class No. 3 (b) includes little travelled connecting or other roads, which should be graded and given such further treatment as cir- cumstances may permit. The relative importance of the several classes, from the builder's and administrator's standpoint, is a matter of cost; not so much the cost per mile as the total cost of each class. On that basis the trunk roads take a minor place and the great body of roads under township councils, rank first in importance. Gradients adopted, amount of camber or crown, width and depth of metal, foundation if any, drainage, binding material, and other details, should, as suggested, be largely dictated by the degree of traffic in accordance with a suitable classification, of which that sug- gested, may form a basis for the purpose of this paper. (Let me here suggest that a good road attracts and creates traffic so that the im- provement of any one road is likely to raise it from one class to a higher grade, which should not be lost sight of in planning construc- tion). A highway engineer should be an economist, for a design adapted to Class No. 1, should not be built where traffic requires only a road suitable for Class 2 or Class 3; or vice versa. Methods 34 AMERICAN ROAD CONGRESS of construction should be as simple and direct as proper results will permit. There should be a well adjusted average between maximum service and minimum cost. If this is studied with good judgment, the advocates of good roads need be less amenable to criticism respecting methods of finance. Class No. 1 Trunk roads Broken stone roads of the best class have been reduced to a few well-defined types, through more than a century of experience in England, France, Germany, and on this continent. The true macadam road has a well-drained and crowned earth sub-grade, over which is spread a uniform coating of broken stone of about 2 inches, in greatest dimension. The Telford road has a foundation of flat quarry stones, placed by hand, on edge, the angular points being chipped off by ham- mer, and wedged into the interstices; and over all is spread a coating of fine broken stone, in thickness about one-third of the total depth of the stone surface. The earth sub-grade is flat, and larger stones are used at the center of the road, with smaller at the sides, to give the desired camber. The roads built by Tresaguet in France, were substantially the same as the Telford road, and are usually included with it. In the French type, the sub-grade was cambered, and the foundation stones of uniform depth. A distinct type of foundation is that developed in Massachusetts, in which there is a slightly V-shaped sub-grade with a filling of cobble or field stone, a method which is claimed to give, more effectively than other types, the desir- able under-drainage. Experience has shown the superiority of roads with a foundation such as the Telford type, in reducing the cost of maintenance under heavy traffic. If the natural sub-soil is strongly supporting, such as dry, cemented gravel, the foundation may be omitted with saving of cost. Whether the Telford or Massachusetts type of foundation be followed, the writer believes that local material suitable for either should largely govern. The width of roadway between gutters or drains, and the width of stone should be guided by the amount and character of traffic, and should ordinarily be less in strictly rural districts, increasing as roads converge into city streets. A minimum width of grade for trunk roads, in the writer's experience, should be 24 feet with metal in the central 12 feet, and earth or gravel shoulders six feet wide on each side. STONE AND GRAVEL ROADS 35 Maintaining shoulders at 6 feet, and a maximum width of metal at 18 feet, the maximum width of grade need not exceed 30 feet. The camber of roads of heavy travel, should be the least possible, consistent with good surface drainage, factors to be considered being the quality of road metal, class of binder, and gradient of the road. As is well known, roads with a sharp crown encourage travel in one central line of wheel-tracks, while a flatter surface permits more uniform wear. A hard rock such as trap, or a bituminous binder, require less cam- ber than does soft material and an inferior binder, while a steep grade requires an increased camber to drain the wheel tracks. Trunk roads of the best class may be given an average crown of one-third or one-half an inch per foot from center to gutter. Class No. 2 County or main market roads Cost is always a factor, but in the case of county and township roads the problem is, more often than with trunk roads, one of limited outlay, or of obtaining the maximum results for a restricted expendi- ture. The general construction of stone roads of the best class, as briefly described, will form an introduction to roads of the more universal type. Roads of Class No. 2, cannot, as a rule, follow closely English, French, German, or other standard, but must be built with a view to the particular needs of this Continent, and of the locality. The need in most States and provinces is a long mileage, to be built as rapidly as possible, through districts where population is comparatively sparse. European engineers, would undoubtedly, if it were possible to recon- struct many of their roads, lay them with foundations, but the cost is prohibitive. No more is it practicable on this continent to build any but the most heavily travelled roads with expensive foundations. Instead, it is necessary to depend on good drainage, carefully main- tained, to keep the sub-soil dry and stong enough to sustain the road surface. Bridges have to be strong enough for the maximum load, and with waterway enough for the maximum freshet. So roadbeds should have sufficient drainage for the severest test, which in northern coun- tries is a period of thaw in the early spring, lasting usually for two or three weeks. If the sub-soil drainage is sufficient for that test- no break-up of the road crust need be feared at other seasons. 36 AMERICAN ROAD CONGRESS Old specifications for roads built in Canada before the period of railway construction required open drains on each side of the road, with bottom at least 2 feet below the crown. In many places the drain was deeper; and hills or spouty places were under-drained by trenches filled with field stone. Such roads have stood the test of time, and may be accepted as the standard of drainage required for the north; except that tile under-drains are taking the place of open ditches where they would otherwise be dangerous, unsightly, or diffi- cult to maintain. Drains of porous farm tile keep the sub-soil at its dryest and prevent uneven settlement of the road crust into mud which is as destructive to a road when below the surface as when on the surface. Some counties of Ontario are using tile drains the full length of all their roads. Others use them only on wet and spouty hills; on level land which is exceptionally wet and retentive; or where the open drains would otherwise have to be dangerously deep to give sufficient fall and outlet. In the last case, the tile may carry some surface drainage, receiving it in catch-basins. Closely associated with drainage is the grading of the road. Before a road is surfaced it should be brought to grades that ensure perman- ence. Hills should be cut down, low places filled, and the earth work brought to a substantial turnpike. The road surface will need renewal, but the grade, if properly made, will outlast even the bond issue. On roads of a secondary class, elaborate surveys are unnecessary. A good foreman can obtain easy, flowing gradients by grading from point-to-point, and would probably disregard stakes and profiles except in cases of extensive cuts and fills, new locations, tile drains, or doubtful surface drainage. Roads laid on an earth foundation should be given a higher crown when newly constructed, than is desirable for perfect condition. Settlement will assuredly occur, and unless the road is too high to begin with, it will become too flat. A road of Class No. 2, which in two or three years has settled to the desirable camber, will give the greatest degree of durability, with least expense for maintenance. One inch to the foot from center to gutter or edge of shoulders, for a completed, rolled road, will meet ordinary conditions. With a circular cross section, the greatest part of the fall is on the earth shoul- ders. The cost of a road, unless earthwork and drainage is of an excep- tional kind, will depend on the width and depth of broken stone used. Wide, flat roads are desirable, but narrow roads with a good camber, STONE AND GRAVEL ROADS 37 cost less to build, and much less to maintain, unless a highly organized system of maintaining is created. We have, for this class of road, found an earth grade 24 feet wide, shoulder to shoulder, to meet most conditions; which may be reduced to 18 or 20 feet for least traffic. With shoulders 6 feet wide, the stone is put on from 8 to 12 feet wide. The consolidated depth of metal on roads under the writer's super- vision, is based on 8 inches for a moderately strong clay or sand sub- soil. This is modified according to the anticipated amount of traffic and quality of stone to resist wear; the maximum concentrated wheel loads; local tire widths and wheel diameters; bond of road metal and consequent distributing effect of the metal crust; the supporting strength of the sub-grade and opportunity for drainage all details of interest but which cannot be dwelt upon within the limits of this paper. Bituminous binders may be justified for heavily travelled suburban or motor roads of this class, but present practice in Canada tends to oiling as a preservative and dust preventive, owing to the less first cost of water-bound macadam. Class No. 3 Township roads Reduction of cost to meet township conditions requires that town- ships have, as their ideal, the cheaper class of roads adapted for main county roads. Grading is cheap, and should be perfected before metal is applied. Neglect to provide easy flowing gradients and to sufficiently drain and turnpike are mistakes fatal to any road. Minor municipalities can make no mistake in placing the perfect earth road as an ideal base for such metal surfacing as their resources will permit. An earth-grade from eighteen to twenty-four feet, shoulder to shoulder, should be made, and a single track laid eight feet wide, of gravel or broken stone. BINDER The durability of a road is largely dependent on the binder, and the cementing qualities of the stone dust, in producing a water-proof sur- face, if tar or other bituminous binder is not used. The writer is strongly in favor of the use of stone screenings as opposed to sand, and has very rarely found gravel or sand sufficiently clean, coarse, and sharp to satisfactorily take the place of screenings as a binder. Wherever practicable, stone screenings are to be recommended, par- 38 AMERICAN ROAD CONGRESS ticularly the screenings of certain classes of limestone; the superior cementing qualties of which make it a better road metal than its degree of toughness would justify. Limestone screenings are exceed- ingly useful with water-washed gravel or with broken granite or trap. COURSING STONE A uniform grade of stone, rather fine, is desirable in finishing the surface of a road, and is necessary where a very hard stone such as trap is employed; but this may be sought at considerably increased cost, and is not always necessary for suitable results. It adds to the cost of a road to spread the stone in several layers. Municipalities using portable crushers particularly, will find a rotary screen with two sizes of mesh very satisfactory. This will produce, (1) "tailings," or the stone too large to pass through the screen; (2) the middle course, a uniform grade to form the main body of the road; and (3) "screen- ings" to bond and finish the surface. The tailings should be spread in the bottom of the road and covered to the required depth with the uniform grade; and this, after rolling, may be lightly coated with screenings and rolled. If a very tough stone such as trap, the screen- ings may be such as will pass a one-inch mesh, or a 1^ inch mesh if limestone; and the uniform grade of stone may be two inches for trap, and three inches for limestone, with the screenings removed. Crush- ing and handling are cheapened by this system and, for water-bound roads, a smooth surface results. LOCAL MATERIAL AND COST Trap or other tough rock brought from a distance by rail in prefer- ence to the use of soft local material, may be justifiable for surfacing heavily travelled main roads; but it is safe rule, if applied with dis- cretion, that local material, if it exists, should be used. Much will depend on the teaming required, but for moderate wagon hauls up to two miles, on highways of the second and third classes, the writer has commonly found gravel roads being built for $100 per mile for each foot in width of metal; if local broken stone is used, the cost is, all things equal, about doubled, or $200 per foot; and if imported by rail, about $300 per foot. Taking then, a road not requiring much grading and with 8 feet of metal and 8 inches in consolidated depth, the cost might be stated, for cheap construction at $800 a STONE AND GRAVEL ROADS 39 mile for a gravel road; $1600 a mile for a road built of local crushed stone; and $2400 per mile if the stone is brought in by rail. These are minimum prices. GRAVEL ROADS Gravel in general is inferior to broken stone as a road material, but if of a reasonable quality, is suitable for roads of the third class township roads and for many market roads of the second class, but unless of exceptional quality is deficient for heavy traffic. The rounded pebbles do not take the mechanical clasp that pertains to fragments of broken stone, while the sand which it usually contains is not equal to stone screenings as a binder. It may contain lime or iron, improving its bonding qualities, but as a rule it is not water- proof and ruts readily in wet weather, especially if it contains sand, clay or loam in excess. The best quality of gravel is of varying sized grain up to 2 inches in greatest dimension, with only sufficient fine material to fill the voids between pebbles. It should be clean and made up largely of a uniform grade of pebbles qualities rarely found in natural pit gravel . Gravel pits containing a mass of large stones and boulders should be treated as rock, and put through a crusher. Gravel which is not coarse, but which is "dirty, " should be screened to remove the excess of sand or clay. A rotary screen may be used, operated by steam, the gravel being dumped into a hopper from which it passes through the rotary screen, and from the screen to an elevated bin, from which the screened gravel is again loaded into wagons to be taken to the road. By means of the elevated bins the expense of shovelling into wagons is saved, the time of teams and teamsters is saved, and a well arranged plant will, under favorable circumstances, pay for crushing and screening, This is particularly the case if a pit near the work can be used rather than to team better material a long distance. METHODS The methods of construction will largely determine the cost. Machine work is cheaper than manual labor. The cross-section adopted should therefore permit the maximum amount of machine construction. Particularly for the cheaper class of roads, the grading machine, in treating with old locations, should do most of the earth- work, supplemented with wheeled and drag scrapers. The cheapest 40 AMERICAN ROAD CONGRESS and best plan, in the writer's experience, has been to make the earth sub-grade, shoulder to shoulder between ditches, almost flat, or with a central rise of about three inches for a 24 foot grade. When this is rolled the stone is spread to the desired width in the center, then with the grading machine, earth is drawn from the shoulders to support the stone, thus completing the camber. The stone is rolled dry to level the surface, the screenings are then spread, sprinkled and rolled till consolidated. To grade the road and then excavate a central channel to receive the metal is a more expensive method, and is apt, for roads without a foundation, to place the stone too low for good drainage, producing what may be termed a "water-logged" road. Instead of the camber and turnpike being high enough to allow for settlement, it is apt to be made too low and flat. ROLLING As distinguished from earlier road making, modern construction has been largely influenced by machinery, especially grading machines, rock crushers, and road rollers. The smaller municipalities of Can- ada, commonly use graders and crushers, but the purchase of a steam roller is too often delayed. It is to be pointed out that the cost of a roller is by no means an additional expense, since rolling effects economy in several ways. Coarser stone can be used in a road that is rolled, so that the cost of crushing is reduced. With coarser stone, the road is stronger to resist wear, and is more securely bonded than if first rutted and mixed with mud. Less stone is required in a rolled road, as loose stone is largely forced down into the mud before the surface becomes water-proof, or is knocked to the ditches by traffic. Without rolling, roads demand attention for one or two years, to rake the stone to place from time to time; the earth shoulders have to be restored and levelled where cut up and destroyed by traffic ; new mate- rial has to be added to fill hollows and ruts. By rolling the sub-grade, the wet or weak spots are developed, which can be drained or filled with earth and again rolled to produce a uniform foundation; thereby reducing the quantity of stone which the road would otherwise absorb. Long lines of loose stone left for traffic to consolidate are a most objectionable obstruction to travel, and bring road-building into disrepute. On the other hand, a road built with a heavy roller is a complete work, in perfect condition when finished. Rolled roads are a revelation to those who have been accustomed to and who STONE AND GRAVEL ROADS 41 expect only old-time methods and results. For economy, service, and to popularize the work, rolling should be regarded as essential for every class of gravel and stone roads. CHAIRMAN PARKER: We would like to hear from Mr. Bigelow, highway commissioner of Pennsylvania, for five minutes. MR. BIGELOW: Now, Gentlemen, what I am going to do is one thing, and what I have done for the State amounts to nothing. In Pennsylvania we are just waking up, I am sorry to say. When we woke up we found about as poor roads as in any State in the United States; but I have made a start, and the legislature has given me over $5,000,000 in cash, to spend next year, and the next year after that, 1913, I will have for the first part of the year $5,000,000 additional, and beginning with about the first of June, $50,000,000 additional to that (applause). They passed a bill and fixed routes in the bill covering 8000 miles of roads. You gentlemen who are accustomed to building roads know that 8000 miles of roads is going to cost more than $50,000,000. But we have no doubt in Pennsylvania that we will get the money; we are a very rich State, and my opinion is that before we get through we will spend more than $150,000,000 (applause.) I have traveled over the State since the middle of July in an auto- mobile, over between 5000 and 6000 miles of road, and we are going to go to work as fast as possible and get them in condition. Since the first of July we have started the work over the mountains, 50 miles, and we will finish that before the next season opens. We have let the contract and are working on 12 miles of the Juniata River; we will finish that before the first of the season. We calculate that we will build 300 miles of roads next year, and get ready for the $50,000,000 at the commencement of the next year (applause). The road subject is not a new one to me, I have been at it for forty years. Conditions have changed, though, and you know the top metal or the top course is the important one at present for wear. I found a road in Pennsylvania, built in 1818 by the United States government; they put in a good foundation, and there are miles of it there today. That is what we want to try to do now, build from the bottom up and not from the top down. I found in traveling over the country that the idea seems to be growing to build cheap roads, to get them for $4000 a mile, $3000 a mile, or $2000 a mile. You can't do it. You might build a mud 42 AMERICAN ROAD CONGRESS road for that. Now I am not going to build cheaper roads, I am going to try to learn a lesson from the government road, that national pike, so that if they look at my roads, a hundred years from now, they will find something left there; I am given a free hand, I am responsible to no person; if I do not build the roads right and lasting, I will be damned, and I am not going to be damned (applause). In the last five or six or eight years, we have had all kinds of " ites " Warrenite, McNickelite, and a great many others. Now you ought to be very careful about putting those "ites" down on top. If that is the proper pavement to put down for the location, build it right, build it from the bottom up, build the foundation right. We are going to build in that way to the adjoining States, and try to connect up and get a system; and after we get some of those roads built, we are going to take care of them. We have in Pennsylvania today, 800 miles of what are known as State roads, built by the State to be taken care of by the townships. I will venture to say that there has not been 10 miles of the 800 taken care of since it was finished. The result is that they are worn out and have got to be rebuilt. Beginning with the first of December, of this year, we are going to establish a maintenance department cover- ing the entire State; and under the act I am entitled to fifty superin- tendents. If it is necessary, we will have fifty districts with all neces- sary machinery for each district; and after that we are going to have a patrol system on every road, and every patrolman will have his wheel-barrow, his pick and shovel and barrel of tar to fix the little holes and keep the road constantly in repair. That is the secret of road building and maintenance, to build from the foundation up and to keep the roads constantly in repair, and that is what we are going to do in Pennsylvania (applause). CHAIRMAN PARKER: We will now hear from Mr. Cooley, of Minnesota. MR. COOLEY: I did not know I was to be assigned any place on this program; I understand the meeting today, was for the benefit of the engineers and contractors, in order that we might exchange our views and learn from each other. Now the best way we can get new ideas here, is for each of us to give a little of the history of his own State, and so learn from others some of the history of other States. Minnesota has about 80,000 miles of road and about 80,000 square STONE AND GRAVEL ROADS 43 miles of territory, so we have about one mile of road to each square mile of territory. Our system of State roads is different from the general rule. Our highway commission does not build any roads, it does not establish any State roads, but that is left entirely to the counties. The county designates certain roads out of the 80,000 miles as State roads; the object of giving them that name and putting them under the jurisdiction of the State, is in order that the highway commission can enforce the regulations in regard to them, which pro- vides that whenever a road is designated as a State road, it must thereafter be maintained under the rules and regulations of the high- way commission. Our 80,000 miles of roads consist almost exclu- sively of earth roads, at least 95 per cent of our roads are earth roads and will be for several years to come. The proposition before us today is not the construction of expensive macadam or gravel roads, but the building and maintaining of roads that metal may be put on in the future. It resolves itself into two things; first, complete and proper drainage, and next, complete and proper foundation. So looking forward to the time when we will have a system of expensive macadam roads, we are establishing a plan of having such repairs made in a permanent manner. We do not allow any perishable mate- rial in them, because that would detract from the foundation. When we come to build our good roads, we will have the experience of our predecessors and their failures to guide us, so that we will not make the same blunders that are being made today. That, in brief, is the history of road-building in Minnesota. We appropriate each year a small amount; heretofore it has been one- twentieth of a mill tax. Next year we will have $300,000 to spend, and we do not spend that money ourselves, but it is provided that the county shall receive a certain proportion, not more than three per cent nor less than one and one-half, and that money is expended under the highway commission. If we carry a proposed amendment to the constitution, it will give us a one mill tax, and after 1913, we will have one and a quarter million dollars, and the counties must put up as much as we put up. All the work done on the roads is done under men appointed under the supervision of the highway com- mission. We have fifty roads engineers now, and we are putting in a system of patrols as an experiment to demonstrate the value of a continuous road maintenance force. The roads of Germany and England and the Scandinavian Peninsula, owe their excellence, not to the excellent way in which they are built so much as to the excellent 44 AMERICAN ROAD CONGRESS system of maintenance; and we think that for the permanent improve- ment of roads it is necessary to adopt a complete system of mainten- ance. CHAIRMAN PARKER: The next to address us is Captain Wilson, of Virginia. There is nobody in Virginia who is not acquainted with him, and a great many outside of Virginia know him. His distinction has reached as far as the backwoods of Massachusetts. EARTH AND SAND-CLAY ROADS CAP'TAIN P. ST. JULIEN WILSON State Highway Commissioner of Virginia From the best information obtainable we learn that only 8 per cent of the roads in the United States are hard-surfaced. When we consider this fact together with the cost of surfacing roads under favorable conditions with stone or gravel and the impracticability of doing it at all in many sections of the country on acccount of the absence of the surfacing material, we realize at once that the question of the proper construction and care of our earth roads is a most vital one. When properly constructed, well maintained and judiciously used the earth road fills the requirement of country traffic for much the large portion of the year; the period of bad roads varying with climatic conditions and the material of which the road is composed. In the construction of earth roads the location is of first importance. This, after all, is the only really permanent thing in connection with any class of road, and, if possible, is of more importance to the earth road than to any other because its surface has less power to withstand the bad effects due to improper location. In making locations many conditions have to be considered together, the two most important of which are the grade and drainage. The grade on an earth road should not be greater than 4 per cent or 5 per cent, that is a rise of 4 feet or 5 feet in 100, not 4 degrees as is provided in the old Virginia law and which is equivalent to 7 per cent; as a grade is increased beyond this rate the load which one horse can draw decreases very rapidly and with light vehicles it is about the maximum grade that a team will trot up or down without considerable difficulty. The grade of a road also seriously effects the maintenance. The steeper the grade EARTH AND SAND-CLAY ROADS 45 the harder the road is to maintain. The cross grade or crown of a road should not exceed 1 inch to the foot or 1 foot in 12 feet, which is about 8 per cent. The longitudinal grade of the road should always be less than the cross grade, otherwise the water will run down the road instead of across to the ditches, thus causing serious damage by washing. So for maintenance as well as for economic hauling the grade should be kept within the limit of 5 per cent, and considerable expenditures in grading or in acquiring new rights of way may be justified to secure such a grade. Where it is impossible to secure the low grades it will be necessary to construct water-breaks in the road to prevent the rapid flow of water down the center. The best form of break is in the shape of the letter V with the point up the hill making a drain to both side ditches, but however well constructed these breaks are, they are hard on vehicles and a serious inconven- ience to travel, and are not recommended except as a last resort. Thorough drainage is absolutely essential for a good road. The water should be taken off of the road as rapidly as possible and then away from the road at frequent intervals. To accomplish this, there must be a crown or cross grade to carry the water to the side ditches. This crown, as stated before, should not exceed 1 inch to the foot; if too steep, it will cause too rapid a flow and consequent washing of ruts in the surface. However it will have a tendency to concentrate the traffic in the center of the road, and therefore, on only a small portion of it causing rapid wear and wheel ruts, these ruts in time collecting water and starting a flow down the road. The water delivered to the side ditches should be carried off immediately by those ditches, on a uniform grade with no holes to form pools from which the water will soak under the road and soften it. In the construction of all ditches care should be taken to slope the banks sufficiently to prevent their sloughing in very wet or freezing weather and stopping the ditches. The side ditches should be relieved frequently by cutting drains away from them or carrying the water under the road in culverts. Large quantities of water accumulating in ditches when flowing rapidly scour them and soon seriously damage the road. It is always best, of course, where possible, to keep a road on high ground, but when it is necessary to go on low marshy ground, the road-bed should be well thrown up and the ditches deepened sufficiently to thoroughly drain the foundation. Another thing to be considered in the location of a road is sunshine. Always locate an earth road where it will get as much sunshine as 46 AMERICAN ROAD CONGRESS possible unless the material is very sandy. A road of deep sand is always best when wet, like the seashore at low-tide. It is always well to consider the material over which a road is to be located. Soils vary greatly in road-building qualities as they do for agricultural purposes. As a rule, the clays and soils of fine texture make poor roads while the coarser and sandy soils make better ones, of course, topographical and other conditions will often prevent the location of a road over the best material which is almost immediately at hand. In such cases the surface of the road can be greatly improved at small cost by covering the whole road or the worse sections of it with this near by material. In the construction of earth roads as with others, the surfaces should be made uniform. Always fill a depression with the same material as that in the road. Do not fill a mudhole with stone and in a short time have two holes, one at each end of the pile of stone, or with brush or vegetable matter, which will SOOD decay and form a spongy spot to absorb the moisture. In quite a large section of Virginia, we have found top soils which make excellent road-surfacing material. In one county we have constructed some fifty miles of this road (at a cost averaging $900 per mile) which compares very favorably with gravel roads built in other sections at considerably greater cost. The method of con- structing these soils roads is extremely simple ; the material is spread upon the road about 12 inches deep at the center, the thickness decreasing to 8 inches at 6 feet or 7 feet from the center and nothing at the edge of the ditch, the crown being about \ inch to the foot. The road is kept in shape by use of the road machine or road drag until it is compacted by traffic and one or two good rains, this method being found for this particular kind of work equally as effective and much less expensive than rolling and sprinking. In localities where these soils are to be found in any quantity we find more or less fre- quently sections of road which keep in good order always. If material similar to that composing these sections is used on other portions of the road, good results may be looked for. Another improved earth road very generally used throughout the South is the sand-clay road, made, as its name indicates, by a mixture of sand and clay. In large areas in the Atlantic and Gulf States the materials for this class of road are abundant and not infre- quently they are found already mixed by nature in the right propor- tions to form an excellent road. Where such sections of natural sand- clay road are found one cannot do better in building a new road then EARTH AND SAND-CLAY ROADS 47 to duplicate the mixture already proven satisfactory as suggested above in connection with soil roads. The ideal sand-clay road is one in which there is just enough clay to fill the voids between the grains of sand. Any surplus of clay tends in wet weather to soften the road, to stick to wheels and con- sequently form irregularities in the surface of the road. On the other hand, a surplus of sand causes the road to disintegrate in dry weather when the sand will be removed by traffic with the same result. To secure the best results, therefore, sand must be added when there is a surplus of clay and clay when there is a suplus of sand. The amount of sand or clay, as the case may be, to be added to the road has to be determined largely by experiment in each case as the materials vary greatly in quality, the tendency is rather to use too little sand on a clay road or too much clay on a sand road. We have often gotten very good results when there was from 2 inches to 4 inches of loose sand over a sand-clay subsoil by simply plowing the road and bringing some of the clay to the surface and mixing. In the construction of sand-clay roads it is absolutely essential that the ingredients shall be thoroughly mixed and puddled. This is most easily done after a heavy rain, the sand or clay having been pre- viously spread, and, if clay, all lumps having been broken, the mixing may then be done with a plow, or better, with a disc harrow. This mixing is sometimes left to be done by the passing traffic, but that should be avoided when possible. It is frequently necessary to make several applications of clay or sand to portions of a road before a proper mixture is secured. After the mixing has been completed the road should be kept in proper shape with a road machine or drag, as it dries out, and kept with the proper crown until it becomes compacted. All that has been said in connection with the location, drainage, etc, of earth roads is equally applicable to sand-clay roads. After a road is built, whether of plain earth, or with some surfacing material it should be kept as nearly as possible in the improved con- dition; that can only be done by constant care and frequent repairs these may be slight and inexpensive, but they are nevertheless imper- ative. No annual or semi-annual round of repairs will keep a road in first class condition. One day's work each month on a road is far better than twelve days' work once a year. A choked culvert or a ditch can be opened at small cost, but, if left stopped, will cause damage to the road many times more expensive 48 AMERICAN ROAD CONGRESS to repair. In cleaning out ditches the material should not be thrown into the middle of the road to raise the worn down center or to fill ruts or holes, for this material is generally composed to large extent of vegetable matter and fine silt and will make the road soft and spongy. Nor should it be placed along the edges of the road, I have not infrequently seen a road force cleaning out the ditches to drain a road and deliberately distributing material along the edges of the road, thus forming a dam to prevent the water from flowing into the ditches. This material should be thrown entirely out of the road and far enough away not to be washed back into the ditches by the first hard rain. For the maintenance of the surface of an earth or sand-clay road probably no implement is so effective or cheap as the road drag, the most common and widely known form of which is no doubt the split log drag. Pamphlets descriptive of this implement and its use may be obtained from any State highway department or from the Office of Public Roads at Washington. A suggestion in reference to it may not be amiss here : Do not make the drag too heavy a great many people in beginning the use of a drag seem to have the idea that the heavier it is the more work it will do. This is a mistake it is much more effective when light. A drag should be used after every heavy rain, though good results have been obtained by using it less frequently, say once in three or four weeks. The dragging should be done when the soil is moist but not sticky. If the road is badly rutted or full of holes, one dragging while it is quite soft is beneficial. In order to keep earth roads in fair condition in winter, some limit should be fixed as to their use, Heavy loads hauled over them on narrow tires when they are soft will necessarily destroy the smooth surface. If the general use of wide tires could be inaugurated, it would, in my judgment, do more for the protection of earth roads, than any other legislation, and, if the people are given a reasonable time in which to substitute them for the narrow ones, no hardships would be worked. CHAIRMAN PARKER: The chair will call upon Mr. Marker, State Highway Commissioner of Ohio, to discuss the subject of the paper. MR. MARKER: I was rather taken by surprise a few minutes ago when I came into the hall and was told that I was expected to get EARTH AND SAND-CLAY ROADS 49 up here and tell you folks what we are doing in Ohio. I try to keep out of such entanglements myself; I am not a public speaker, and since you have all listened to a flow of oratory ever since you have been here, I feel that I am a little out of place. But, laying that aside, I feel that I ought to say something in my own humble way, concern- ing our State of Ohio. Highway development in our State is about seven years old. It was begun in 1904, and it was merely a nibble at that time. The department was composed of the State highway commissioner, one deputy and three division engineers; the appropriation was very small, divided among many counties, and the department proceeded to build sample pieces of road in various places. These roads or samples were selected in most instances, by the county commissioners of their respective counties, and I want to say that the people in our State are looking out for themselves in a measure, and it is peculiar to say that these samples were selected many times alongside the commis- sioners' homes. The old law operated for about six years until last year, and the growing demand for good roads necessitated a change. Under the McGuire bill which was passed at the recent session of our legislature, the department was reorganized and we now have at the head of the department, the highway commissioner, with three deputies, eight division engineers, and numerous resident engineers, clerks and stenographers and the nucleus of a library. We have three bureaus, the bureau of maintenance, the bureau of construction, and the bureau of bridges. The bureau of maintenance is supposed to take care of the State roads, or those roads built by the use of State money; at present the bureau of construction is classifying the roads of the State under what is known as the inter-county system. The bureau of bridges is taking care of the bridges on the pieces of road constructed by the department, and they are obliged to prepare plans and specifications for bridges for any county that may ask for them. At present that is not generally known throughout the State, or we fear that our department would not be able to supply the demand. We have in our State about 90,000 miles of road, in round numbers, about 5000 miles of which are free delivery routes, and about 8000 miles would fit into an inter-county system. Our levy gives us this year about $630,000 for the construction of roads. This money is divided equally among the eighty-eight counties. Before any of this money is applicable to a county, the county must raise an equal amount or more; so we have, approximately, for construction this 50 AMERICAN ROAD CONGRESS year, $1,000,000. We feel that this amount is but a drop in the bucket for the building of roads in our State. Next year we contemplate building about 200 miles. Assuming that we would continue to build 200 miles of road a year, to construct all the roads of the State would take us about four hundred years; to construct 8000 miles would take us about forty years. Now we want good roads in our own day, we are not looking forward to the future to such an extent that we want to build and prepare for posterity and pay for these roads and deliver them over in good shape. We have the method, we have the equipment to build roads, but we have not the funds sufficient to build them, so we are working towards that end. The present State constitution limits the State in the issue of bonds to about $750,000 for all purposes; if that were divided up equally, it would not mean . much for good roads. The next constitutional convention will assem- ble in January, and the good roads enthusiasts in our State are going to force through a raising of the bond limit that we may be able to bond the State for the sum of $50,000,000 for good roads. That is our program and that is what we are working towards. We want State aid, and we are not going to stop at State aid; we are for Federal aid. We are pledging our congressmen, and we are pledging our senators; and we hope in the course of ten or fifteen years, to have the roads in our State up to a very high standard, and we expect to do that by getting more means. We want the federal government to help us and help the rest of you (applause). CHAIRMAN PARKER: The program will now proceed with a paper delivered by Major W. W. Crosby, of Baltimore, who is the State highway engineer of Maryland. BITUMINOUS ROADS MAJ. W. W. CROSBY Chief Engineer, Maryland Roads Commission It is not the purpose of the speaker to trace the history of bituminous road work from the early efforts of the Peruvians, nor even to review the work of this country for the past forty years, but rather to touch merely on some of the points in it at present of so much common interest and, in so doing, perhaps to suggest a thought or two that may be of value in stimulating consideration and discussion of this impor- tant subject. BITUMINOUS ROADS 51 For surfacing roads usually called " streets" in cities, the larger practice with bitumen has been to use it in the form of asphaltic cement, such as in sheet (or block) asphalt pavements. Such pave- ments, under proper conditions, give good satisfaction at reasonable expense. The first cost of them varies between $1.50 and $3.50 per square yard, however, and in recent years an effort has been made to secure a similar surface, of even wider applicability, at reduced cost. Incidentally, success in this line would offer a much needed surfacing for filling the gap between the best macadam cheap but sometimes of questionable satisfaction, and the rather expensive asphalt pave- ments referred to. In this effort, the use of cheaper bitumens such as the tars for instance has been tried and also new methods and mineral materials for the body of the pavments cheaper than the graded hot sand required for the sheet asphalt. Much success has been had and, naturally, some failures. This work, as a whole however, in the cities has been so like the development of the country roads along the same lines, and the distinction between a highly developed country road and a minor street in a city is so lacking in clearness that we probably may proceed, with this reference to city work, to the consideration of road work proper. Bituminous roads constitute a modern development to meet both the actual needs under modern traffic and the desires of modern civilization for greater efficiency, comfort, satisfaction and better sanitary conditions. The advent of the motor vehicle has greatly changed the conditions under which a road existed. Good roads are in greater demand owing to the greater radius of action of the auto- mobile. Smoother roads are more desired because of its sensitiveness, at its greater speeds, to the slighter inequalities of the road surface. More cementitious surfaces are needed, due to its ability to destroy the bond of the stone surface, to cause internal friction and wear of the pieces of stone forming the crust, and to render the road thus more susceptible to the elements. And further, the dust, which formerly laid on a good road surface and, which, when not too profuse, was not only not seriously objected to, but was of some actual value in the protection which it afforded the stones composing the road, has been violently brought to our attention by the motor so violently and powerfully in fact that we are now well aware that, under present conditions at least, the disadvantages, discomforts, and unhealth- f ulness of this dust far outweigh any good it may formerly have pos- sessed. 52 AMERICAN ROAD CONGRESS None of us believe that the remedy for this state of affairs is the aboli- tion of the motor-vehicle. Most of us who do not possess one are looking forward to the day when we may, and most of those who already are fortunate enough to own one are anticipating the posses- sion of two or of more. So the remedy seems to be to cure the defects of the road. And the speaker wishes to here again repeat what he has frequently said before, i.e., there is no one "best way" nor one "best material." The decision as to method or material to be used must depend in each case upon conditions of traffic, availability of different materials, desires of locality, and probable changes of conditions during the life of the work decided on to be done. A clear recognition of this fact is important for good work and economy. It is somewhat sur- prising how often it appears to be overlooked even among those who would be expected to appreciate it most. Let us suppose now that we have the improvement of a certain road contemplated; that the details have all been worked out except as regards the road surface itself; that there is no question but that as soon as the road improvement is completed, a considerable number of motor-vehicles will use the road daily, say, not less than twenty every twenty-four hours. Then there is no question but that the road should be treated with bitumen either during or immediately after the construction of the surface with gravel, shells or broken stone, if economical and satisfactory maintenance is to be had. Its treatment may also be justified for other reasons. There may be said to be three ways in which a road surface may be treated with bitumens. There are (a) The mixing method; (6) The penetration method; (c) The method of surface applications after construction in the ordinary manner. A choice of these methods depends, as before stated, upon condi- tions. Such choice may be largely affected by traffic figures but it is not yet clearly established just what amount of traffic demands justifies a selection of one method from the others. We are acquir- ing information on this point and it is hoped it may soon be clear. Generally, however, the choice is largely affected by other consid- erations, such as of comfort, health and satisfaction to the users or abuttors and the speaker believes that in making the choice it is well to be on the safe side from all these view-points. It is almost inevitable that, once a road is well improved, the previous traffic records will become almost worthless except for historical purposes. BITUMINOUS KOADS 53 Consequently be believes that apparent extravagance in the choice at first may often prove later to have been true economy. Although the speaker referred to construction alone in the fore- going, the remarks apply equally well to reconstruction or repairs to a road that has deteriorated beyond the point where a surface treatment alone can be safely expected to relieve the needs. At this point the speaker must inject the remark that it is his opinion that reconstruction is often attempted when a thorough surface treatment is all that is needed not true economy. He is convinced that in the near future the use of proper surface treatments will be far wider and of greater satisfaction than it has been up to the present Now, the mixing method, as the term is generally understood, con- sists of mixing with the mineral material composing the wearing course of the road a sufficient amount of bituminous cement. This mixing is usually done at a plant off the roadway itself and even per- haps some distance from the site of the work. The materials may be mixed, either heated, or at the normal temperatures of either or both according to the method and materials employed, and by hand or by machinery for the purpose as desired. The mixed material is then taken to its place, spread and rolled and then frequently given a flush coat of bitumen and grit and again rolled. Satisfactory results from this method cost from 30 cents to $1.50 per square yard over and above what would have been the cost of an ordinary modern water bound road under the same conditions. The advantages claimed for the mixing method by its advocates include great uniformity of surface and of composition of same, maximum value of surface for materials used, economy in use of materials, maximum life of surface and economy of results. There seems to be no question but that the mixing method has been proved capable of producing high class results. There is grave doubt if it has always been the economical method to have followed, and there are many instances of its utter failure. The mixing method frequently involves a considerable invest- ment for machinery and this fact with the higher first cost has led to the development of the penetration method. In brief, the penetration method consists of simply applying a coat of pitch to the wearing course of the road just before the binding of this course by dusting, watering and rolling as usually practiced in modern water-bound work. The pitch may be applied cold if properly prepared, though it is usually used hot, After its application, the pitch is coated with grit and the road thoroughly rolled. The cost 54 AMERICAN ROAD CONGRESS of the penetration method varies between 10 cents and 60 cents per square yard, above the cost of water bound work under the same con- ditions, according to methods, materials and quantities of the latter used. The advantages claimed by its advocates include sufficient uniformity of surface, economy in first cost, economy in long run, simplicity of operation and avoidance of complicated and expensive machinery, not to mention freedom from interference by patent infringement claims. There is no doubt but that high class results can be secured by the penetration method. There are plenty of records of failures however. The method of surface treatment is only applicable to road surfaces already finished under other methods, usually to old or new water- bound work. In brief, the method consists of cleaning the old surfaces to be treated so that it shall be free from all fine material and refuse, even to washing it with water if this be necessary. After such clean- ing, and when as dry and warm as practicable, the pitch is applied; allowed to soak into the surface for a longer or shorter time as the material used may demand; then covered with grit, and rolled. The process of applying pitch and chips may be repeated immediately, or after an interval as may be necessary. Sometimes two or more applications of pitch and chips are necessary for satisfactory results, and the interval between applications may vary from a day or so to a year or more, depending on local conditions. The pitch may be spread by hand or machinery as convenient, and either cold or hot, as its character may permit. The cost of surface treatments varies from 5 cents to 20 cents per square yard. The advantages claimed for this method by its advo- cates include simplicity of work, economy of first cost and, in many cases, economy in long run, lack of serious interruption to use of the road, ease of repairs and renewal. Unquestionably satisfactory results have been secured under the method of surface treatments, and the speaker believes this method offers an easy and economical way for the revivifying of a road, about to otherwise need resurfacing at a far greater cost under old water bound methods or under either of the other two methods of employing bitumen. The earlier success of the mixing method and the consequent attracting of attention to this method led many road workers to rush into it, believing it to be a panacea for all the road ills they were familiar with. A little later its extravagance in many cases became apparent and the penetration method received some followers. Still BITUMINOUS ROADS 55 later the unnecessary expense of even this method became apparent for many cases and the method of surface treatments developed. Unquestionably, each method has its uses and the proper selection of one for a particular case is the end to be aimed at. The sphere of action of each is merged with or overlapped by those of the others and it will be some time yet before they can be clearly separated. The method of surface treatments is particularly applicable for use on old roads, and as water bound roads will predominate for the near future at least, so will surface treatments grow in use. The speaker is unable to wholly agree with a statement that has been made elsewhere to the effect that "the water-bound road is a thing of the past. " He is yearly building a hundred or more miles of water bound road and looks for such work to be continued indefi- nitely, as there are many localities where dustiness is less objectionable than increased first cost. But as these water bound roads develop traffic over them, and as their extent and age increases, there comes a time when treatment is demanded, and then surface treatment with pitch is often most advantageous and satisfactory. In each of the methods referred to, a variety of materials may be used. At the present time, except possibly in the case of certain asphalts used for pavement work, the critical characteristics of a bituminous material to insure its being satisfactory in use under any definite method or conditions are not settled. Gradually, experience with them is clearing up the probelm, but it is likely to be some time yet, owing to the variety already available and new forms yearly coming out, before definite knowledge will be had. Such knowledge will, of course, be hastened by co-operative effort, such as this meet- ing, and careful co-ordinated records of work done, which records are already being collected by the committee of the American Society of Civil Engineers. About all that can be said now is that certain materials will generally give good results; many materials will be satis- factory when properly used; some are extremely limited in their application; and some are practically worthless. In the foregoing, we have perhaps dealt mainly with the use of bitumens or pitches in connection with ordinary road materials. And, it may seem that it all was toward the end of improving what would, in many cases, have been a fair road, or under earlier condi- tions have been an excellent road. There is, however, another large consideration for the wider use of bituminous materials in road work. By such use, many materials otherwise unfit for road surfaces such 56 AMERICAN ROAD CONGRESS for instance, as the harder sandstones, granites, flints, etc., without binding powers can be most satisfactorily availed of to great advant- age in many cases. Also, by the use of bituminous materials, oyster shells, marl and even sand, can be made to cheaply form a road surface that is both highly satisfactory and most economical in a great many instances. And again, by the use of a relatively light and cheap "carpeting" of pitch and stone chips on its surface, the speaker believes many, if not all, of the defects of concrete for a road surface will be overcome. If so, a large avenue is opened for progress toward satisfaction and economy. The selection of proper methods and materials to fit the conditions is the particular province of the unbiased and competent expert, and should not be attempted by the inexperienced nor entrusted to an ignorant or prejudiced party unless failure in some feature of the work is to be expected. The speaker wishes to briefly suggest two thoughts more : The first cost of bituminous roads is not a correct basis for the proper comparison of either materials or methods, for desirable, even satis- factory as such roads may be, they, like all other roads, require also maintenance, and this maintenance means expense even though re- duced from the earlier figures for such work. And such maintenance should be, with bituminous roads as well as with any others, prompt, sufficient and efficient. MR. PRATT: Mr. Chairman, as we all know, the work of this Association and the progress of this congress will be made known to the public in general, not by the speeches made here, not by the papers read, but through resolutions that this congress adopts. As the work of the committee on resolutions is going to be very hard work, and the men on that committee will have to give up their whole time, and miss a great many of these sessions, I would move that the committee on resolutions be completed now and appointed by the chair so that they can begin their work Seconded and adopted. CHAIRMAN PARKER : I will announce the names of the committee, which is the result not of my wisdom but the united wisdom of a great many minds. The committee is as follows: consisting of four- teen names, I think. Chairman, T. Coleman du Pont, Delaware; Leonard Tufts, North Carolina; Jesse Taylor, Ohio; W. A. McLean, BITUMINOUS ROADS 57 Toronto; J. A. Stewart, New York; W. W. Crosby, Maryland; W. D. Sohier, Massachusetts; Mr. T. G. Norris, Arizona; Mr. R. J. Potts, Texas; W. J. Roberts, Washington; P. St. J. Wilson, Virginia; R. A. Meeker, New Jersey; Colonel Sidney Suggs, Oklahoma; Dr. J. H. Pratt, North Carolina; A. N. Johnson, Illinois. MR. KENYON: Mr. Chairman and Gentlemen of the Convention, I am not expected to make a speech, and I am only going to take a very few minutes now. I cannot refrain from making a suggestion in regard to bituminous roads. We have all seen so many excellent examples, that we wonder why there are not more of them; and then the minute we come to make a particular study of how to obtain them, to make sure that we will get good ones, we find all sorts of difficulties confronting us at every turn. We look into the surface treatment, and we say, " Oh, my, how did you get this success? " The same is true of other methods. We are making progress, but we are not going to make a great deal of progress until we are able to standardize in some way these bituminous materials. It seems to be the idea of almost everyone that the chemist is the one to make this solution. I do not believe that we are going to have much success as long as we follow that idea. You remember that when we commenced with Portland cement, they said it was a chemical problem and it was for the chemist to solve, and we made very little progress as long as we followed the chemist; finally we obtained a method of determining the physical qualities of the cement under certain conditions of temperature and moisture; and by always mixing it the same way we found that it would stand 300 or 400 pounds pressure per square inch, if not more, by the test of the crushing strength and the tensile strength was also tested, and when we found certain standards we adopted them, and the results have been uniform and there has been little trouble since. When we determine that as to bituminous cement, and some are working along that line now, then we will have success and get the similar results with it as we do with Portland cement. One suggestion I haven't heard anything about, in any of the papers, and I want to commend it to the road-builders and engineers, is in connection with the penetration method of making bituminous pitch roads. I was going with Colonel Brodie, of Liverpool, England, over some bituminous roads he had constructed by the penetration method, and he made this variation from the ordinary method of handling the materials. He heated, of course, the bituminous material, which in 58 AMERICAN ROAD CONGRESS that case was pitch or refined tar, and just before he poured it in the road he incorporated in it about 50 per cent of hot fine sand, not so much that it did not pour, and the man who attended the tank kept stirring it, and another man dipped it out and poured it on the road. You could see the sand cling to the rocks on which it was poured, and it held the pitch in place. It is known that in all bituminous cements the adhesion to other surfaces is greater than the cohesion to itself, consequently he got in that mass double strength. I saw some pave- ments that he told me were laid eight or nine years before, in that way, and really I was astonished to see how well they had endured. I haven't seen anyone who has tried that plan in this country. I suggest it to you. It looks good to me. The results that I saw were good, and I commend them to the consideration of those who study the problem. I am much obliged to you gentlemen for listening to me this long. MR. GULICK: I would just say a few words. Bituminous roads are all right for cities, but not for the country, we can't afford it. Now what are we going to do? We have got to have something else, we can't afford to go to that expense; any of you men who live a good ways out from town know that. CHAIRMAN PARKER : The next speaker is that well-known charac- ter, Mr. Arthur H. Blanchard, formerly of Rhode Island, and now of New York. There is probably nobody in this country who knows as much about road building as Professor Blanchard, and he is going to give you some of the matters relating to the cost and maintenance of roads. ROAD COSTS AND MAINTENANCE ARTHUR H. BLANCHARD, M. AM. Soc. C.E. Professor of Highway Engineering, Columbia University, New York The propaganda of the American Association for Highway Improve- ment contains the following important fundamental principles: First : " The elimination of politics from the management of public roads. " Second : 'The introduction of skilled supervision in the manage- ment of public roads." Third: " Continuous and systematic maintenance of all roads." ROAD COSTS AND MAINTENANCE 59 Fourth: "The classification of all roads according to traffic requirements. " It is only through the medium of the recognition, dissemination and fulfillment of these axiomatic principles that the important prob- lem of the adoption of that type of road or pavement best suited to local conditions from the standpoints of economy and efficiency can be successfully solved. The determination of the most economical and efficacious method of construction and maintenance to be employed on roads of various classes constitutes one of the most interesting subjects which the highway engineer has to consider. The solution of the problem depends upon many variable factors, all of which must be given due consideration and the proper value attached to each. The great variety of materials and methods of construction and maintenance used, together with the absence of such essential information as traffic censuses, cost data, etc., makes it a difficult matter sometimes to reduce all of the different types of roads to a comparable basis for a given location. It is only within the past few years that any- thing has been done relative to a scientific method of taking traffic censuses on trunk highways. At this time, however, there is consider- able valuable information relative to the construction or maintenance of roads to meet modern traffic conditions. Another source of con- fusion is the conflicting reports as to the results obtained by the use of a certain method or material. In many localities where engineers have adopted some one general method for construction or maintenance it may be found that such methods, although they may be successful as far as use is concerned, are not the most economical types which aro equally efficacious. The cost data covering construction furnished by many highway officials unfortunately is so brief that it is practically worthless. Many times in otherwise elaborate reports a total cost per mile is the only information furnished under the heading cost data. It is self-evident that in order that cost data should be of value to the public and the engineering profession besides a complete description of construction, characteristics of materials employed and local conditions, there should be given figures relative to rates of labor, cost of equipment and detail data covering construction. The topic "Road Costs and Maintenance" will be considered from the viewpoint of the annual cost to a community of improved high- ways of various types. Annual cost is a combination of the following variables: Interest on the initial cost of the road, the annual main- 60 AMERICAN ROAD CONGRESS tenance charge, and an annuity which will in n years, the so-called life of the road, provide a fund equal to the cost of reconstruction. In the case of types of roads permitting partial reconstruction every m years, a second annuity should be included. As an illustration of the second case will be cited the practice of Parisian engineers in the reconstruction of wood block pavements. The surface of this type of pavement is maintained by the substitution of good blocks in such places as depressions have been formed usually attributable to excessive wear of blocks of poor quality. After a certain pe- riod the entire wood block surface is taken up, the blocks planed off and relaid. Again in the cases of many types of roads having as a characteristic a broken stone surface a partial reconstruction of from one to two inches hi depth is required every few years. The other factors enumerated under annual cost need no explana- tion with the exception of maintenance charge. Unfortunately hi maintenance we have a much abused word, as the standard upon which the definition of maintenance rests varies widely through-out this country. Hence reports relative to the cost of this item as a factor of annual cost are of little value except in those cases where it is known what the highway officials mean by the statement that a road is well maintained. The ideal maintenance, which should be striven for in every case, is a method by which the surface of the highway is kept in as good condition as when accepted on the com- pletion of construction. It is self-evident that it is only possible to con- form to this ideal by the adoption of the principle of continuous maintenance. It is certainly deplorable that hi the case of some of our public work the idea of maintenance possessed by certain lay boards will permit the surface of a macadam road to remain covered with loose broken stone caused by disintegration due to motor car traffic for a period of over two months. This practice in cases where funds are available for the improvement of the conditions noted is obviously absurd to designate as maintenance. Rather it should be characterized as criminal negligence. This Association has an admirable opportunity to emphasize the absurdity of the popular idea that an appropriation for the construction of a highway will provide a surface which, once constructed, will endure until eternity. Unfortunately, first cost in many cases is the only element which is considered in the selection of the type of road while in other cases the number of years which a pavement will last or will remain dustless is the only factor given due weight. The interest charge, maintenance ROAD COSTS AND MAINTENANCE 61 required and the annuity item seldom receive the attention deserved. Although it is self-evident that the problem cannot be solved exactly, nevertheless it is practicable to analyze the problem presented in a manner that will give as satisfactory results as are characteristic of the results obtained in many engineering problems of a similar type and thus approach within reasonable limits the ideal of economy and efficiency. An ideal road or pavement should be durable, noiseless, sanitary, efficacious for road users, easily cleaned and made dustless, provide good foothold for horses and be non-slippery for all classes of vehicles under varying climatic conditions, yield neither dust nor mud, have a low tractive resistance, low annual cost, low first cost, low main- tenance charge, and an esthetic and impervious surface. It should not be considered, therefore, that the idea of annual cost is paramount in every instance. For example in Monaco, the winter home of the father of superficial tarring, Dr. Guglielminetti, ordinary macadam made absolutely dustless by ideal watering has been adopted because the primary prerequisite in that case was of an esthetic char- acter. In this instance it was necessary to select a dustless surface which would harmonize with the tropical gardens and yellow lime- stone palatial cafes, hotels, shops and villas clustered about the Casino of Monte Carlo. Again, although the annual cost is greater, many engineers favor the use of a bituminous filler for brick pavements rather than a cement grout filler because the pavement constructed with the former is not as noisy as with the latter. As illustrative of the method of analysis which should be employed in consideration of annual cost, a few examples will be given of cases which have come under the writer's observation. The first illustration cited refers to a road built of water bound macadam located in an isolated and exposed district subjected to a traffic of five horse drawn vehicles and thirty motor cars per foot of width of a 14 foot roadway during the period from 8.00 a. m. to midnight in the summer season. A large percentage of the motor traffic consisted of heavy touring cars, limousines and landaulets traveling at speeds between 40 and 55 miles per hour. The kind of treatment adopted consisted of the periodic application of light oil, which, under the traffic and other local conditions, was efficacious from the standpoint of dustlessness for a period of one month. The annual cost of a superficial treatment with a bituminous material will be investigated for comparison. The interest on first cost and the annu- 62 AMERICAN ROAD CONGRESS ity will be considered the same in both cases although it is self-evident that the bituminous surface road will have a much longer life. The light oil was used during the maximum period for this locality, that is from May to November, inclusive. The cost of oiling, being 1 cent per square yard per treatment, was 7 cents while it was found that the cost of repairs to the macadam surface was 3 cents. It should be said in this connection, that, although the surface was main- tained dustless throughout the above period, disintegration by high speed motor car traffic took place. The total maintenance charge was 10 cents per sq. yd. per year. On the other hand if an annual superficial treatment had been employed, thus providing a bituminous surface which would have been efficacious throughout practically the entire year, the average cost of the superficial treatment would have been 5 cents per square yard while the repair item would not have exceeded 0.5 cents, thus giving a total maintenance charge of 5.5 cents as compared with 10 cents with the light oil. In another case coming under the writer's observation, it was decided to first construct a water bound macadam and afterwards provide a bituminous surface by superficial treatment. The annual cost of a bituminous concrete pavement, finished with a flush coat which, under the traffic to which this road was subjected, would last five years, will be investigated for comparison. Granted that it will be necessary to reconstruct both roads by replacing the wearing surface of 2 inches every twenty years, the annual cost may be compared as follows: For the annual superficially treated road, the first cost was 67 cents, the interest charge at 4 per cent, 2.7 cents, the main- tenance charge 7 cents, composed of a 5 cents charge for annual bitum- inous treatment and 2 cents for repairs, the annuity, 0.9 cents, based upon the cost of reconstruction. Hence the annual cost will be 10.6 cents. In the case of the bituminous pavement the first cost would, under the existing local conditions, be 90 cents, the interest charge 3.6 cents, the maintenance 2.5 cents, made up of a repair charge of 0.5 cents and the cost of the flush coat, having a life of 5 years distributed throughout this period, of 2 cents, and an annuity of 1.7 cents, thus making the annual cost 7.8 cents as compared with the annual cost of the superficial treatment of 10.6 cents per square yard. It will be noted that the annuity covering total-reconstruction is not consid- ered in this case. In the opinion of the writer the advantage would be with the bituminous pavement. The lack of appreciation of the intimate relationship existing KOAD COSTS AND MAINTENANCE 63 between road costs and maintenance is attributable to many causes among which may be noted the following: First: Political interference in the selection of the men placed in control of highway work, and with the work of design, construction and maintenance of roads and streets. Second: The interference by controlling bodies of laymen in the legitimate work of the highway engineer. Third: Division of responsibility in the supervision of highway work, particularly in municipalities, but also applicable in some States, as for instance, those in which the State department super- vises the design and construction, while the responsibility for main- tenance is placed upon the county or town. Fourth : The comparatively small number of well-trained highway engineers who have devoted the requisite time and energy to the new problems which have arisen during the last decade. Fifth: The comparatively infinitesimal amount of investigation which has been considered necessary as preliminary to the design of a road or street or a system of highways. Sixth: The general meagreness of detail knowledge of the many different materials on the market and the varied methods in connec- tion with which they may be used. Seventh : A confusion of ideas on the part of many as to the rea- sons for the success or failure of various methods considered both from the standpoint of road preservation and dust prevention. Eighth: Nonobservance of the relationship between the adapt- ability of various methods and the variability in the cost of labor and materials, and the accessibility of new bituminous materials and machines. Ninth: The search by many officials for a panacea for the treat- ment of all classes of roads and streets. By an analysis of this brief outline of the relationship existing between road costs and maintenance it is apparent that the principles enunciated heretofore must have the enthusiastic support of all interested in highway improvement if economical highway construc- tion and maintenance is to be characteristic of the future development of American highways. MR. Cox: I come from Prince George County, in Virginia, in which we have no material for the building of what would be con- sidered permanent roads as outlined in the papers and addresses 64 AMERICAN ROAD CONGRESS delivered here, such as rock or stone. We have very little gravel, but lots of sand and clay. I am more interested hi the sand-clay road improvement than in the so-called permanent road. In Mr. Wilson's paper I noticed that he discussed the use of the split-log drag for use on the sand-clay road; whether hi his paper he suggested the cleaning out of drains or ditches along the roadside and the turning of that material which has been deposited hi the ditch entirely out of the road, I do not know. I would like to ask Mr. Wilson, if he would suggest the throwing of that material out of the ditches ahead of the split-drag, or would he let the drag do the work? If he does not throw it out ahead of the drag, the drag would necessarily draw it to the center of the road, which he says is objectionable. CHAIRMAN PARKER: Can you not reverse the drag so as to throw it outside? MR. Cox: Then you would have to use something besides the split-log drag to get it out of the dram. I just want to know whether he would recommend throwing out by shovel or other means, the entire deposit that had been made hi the ditch ahead of the split-log drag. CHAIRMAN PARKER: You will have an opportunity of conferring with Captain Wilson on that any time you like. We have about half an hour more, and there is the subject of brick and other road materials to be considered. Prof. Edward Orton has telegraphed that he cannot be here, so you will miss the paper which he has written: but I am going to make bold to call Mr. Blair, of Cleveland, to say a word, he is an expert on brick roads, and a very ready and continuous talker, and I have no doubt that if he were allowed to proceed he would entertain you the rest of the day, but I am going to ask Mr. Blair if he will talk about twenty minutes. MR. BLAIR: Mr. Chairman, Ladies and Gentlemen I very much regret the absence of Professor Orton who would doubtless give to you more readily the information this audience would like to hear, regarding brick roads, than I. But I learn that family affliction kept kept him away from this convention. We have heard, I believe, every kind, manner and method of building every road, and the main- tenance of roads, from the platform, with the exception of brick; KOAD COSTS AND MAINTENANCE 65 and as my time is so limited I believe that it can be more profitably employed if I would simply relate to you the chief ideals of construc- tion of a brick road, and I will rapidly pass over the items and details concerning the necessary construction of a brick road, so as to make it render the best service, because I believe if there is any road on earth that eliminates the maintenance charges, it is a properly con- structed brick highway. The proper dimensions of a brick highway, where they have been in use for a number of years, is 14 feet in width with a 7-foot clay track on the side. Many of them are built about 9 feet in width with a 7-foot clay road on the side; such roads measure a yard for every lineal foot. Such roads are built in many parts of this country at a cost of $80000 to $10,000 a mile. They have underneath that a 4- inch concrete base; that 4-inch concrete base is advisedly made smooth. Upon it is placed, a 2-inch sand cushion that is uniformly compressed by using a hand roller weighing about 350 pounds. Two things are accomplished by that method You have a uniform wearing plate, you have a support of the wearing surface that is uniform, and yet it has resiliency, so that neither the brick nor the cement that is placed between the brick is at all injured in use, and will last indefinitely. After this foundation is thus prepared, the bricks are placed upon it with the best edge up, and after that the pavement is smoothed, and then it is ready to receive the application of the cement filler. And just one word before I describe how the cement filler should be applied to the joints of the brick. I want to say that any other kind of filler in brick streets is not advisable at all, that it is an error to suppose that the use of the soft filler does away with the noise; rather the cement filler tends to lessen the noise during a period in the use of a brick street covering its life, because the soft filler will gradually pick out, the brick will chip, and it grows more noisy, as it grows older; while with the use of the cement filler, such as described to you, the brick street becomes smoother and less noisy as it grows older, because it is in better condition from year to year, we don't know for how many years. Now in the application of the cement filler, the secret of obtaining the quality is that the cement filler shall be made in the proper pro- portion and that proportion is one to one of cement and sand. The only way to keep it in that proportion is to keep it in perfect agitation until it lands in its place, and then after it becomes hardened, it is uniform in character throughout and any expansion and contraction 66 AMERICAN ROAD CONGRESS which we are often called upon to explain is almost eliminated, be- cause that is taken up in compression. But whatever remains may be taken care of simply by means of an expansion cushion alongside the curb. Now, as to the curb, for a country highway, it is advisable, simply to build it flush with the pavement, so the teams can pass on or off that pavement without let or hindrance. Now, as to its quality, after a pavement is thus constructed it is almost impossible for it to get out of order, and I am almost inclined to refrain from speaking the facts with reference to the durability of brick pavements thus constructed. We never have had a brick pavement in this country to call for repairs in twenty yearn, and that is something worth while that the American people ough^ to know. I am not an advocate of the use of brick generally and indiscriminately; you must have the sand-clay roads, you must have the water-bound macadam, you must ha^ e the water-treated roads we have heard so much about. But upon excessively used roads like the great through- fare from the city of Washington to the city of Richmond, over which would come continuously in almost unlimited numbers automobiles, trucks, farm wagons and traffic of all kinds, there is but the one pave- ment on this earth that is economical to construct upon such a high- way, and that is either granite or brick. Of course a granite pave- ment would be out of the question, but brick is not prohibitive in cost for excessively used roads, and it is the solution of the problem as to the material for excessively used highways that the American people demand. Why, it would be utter folly to use any other material to construct a road in the State of Illinois, that is expected to bear 14,000 bushels of grain to market from every quarter section of land, as is the case in many sections of that State. I had a photograph taken a little while ago where such a farmer, at a distance of 2\ miles from market, with teams of two horses and five wagons, averaged 319 bushels per load, at a cost of less than 1 cent per ton per mile for such work. That is an extreme example, but it affords an opportunity for study and consideration as to the possibilities of brick paved roads in this country. I just want to recite for a moment some of the history in places where these roads are the most popular in the country, and that is in the vicinity of Cleveland, Ohio. In the county outside of the limits of Cleveland, we have about 400 miles of brick paved country highway. If you will get into the commissioner's office of that county, ROAD COSTS AND MAINTENANCE 67 you will find at this minute twenty-two farmers petitions for that many additional roads awaiting the action of the county commissioners and the money with which to construct them, so popular are they. Something like five years ago a realization came to the people as to the possibilities of these roads in that county to such an extent that the farmers along at least two roads within the county petitioned for brick roads, though they had yet five years to pay out on their water-bound macadam. What is the result in that county? Farm values have been doubled in a large part of that county, and a farmer is within just as easy touch of the city of Cleveland, 20 miles out on that road, as he is within a mile and half. Now I do not know that I can say anything further in the few min- utes allotted me, but I feel that I have said enough. Although I cannot go into details and recite to you all the evidences of the eco- nomic value of brick roads on the excessively used highways of this country. I will state two or three of the advantages; the traction resistance is less than that of any road; it does not originate dust, and a farmer with the utmost comfort can have his house by the side of the highway without the dust flying in his window and in his yard; you can get about any time of the year. But the chief virtue of that road is that it is never out of repair, and it is good for use night or day, winter or summer, wet or dry. CHAIRMAN PARKER: We are a little ahead of our program and time, and there have been several of you who seemed to want to ask questions. Any of you who would like to ask questions I will be very glad to entertain them; and if I cannot answer them, I will refer them to Mr. Page, who can answer any known question; so I hope that any one of you who wants information will ask questions. MR. GILBERT: I had occasion two or three weeks ago to fill a place in a road, and I looked at the act of 1904, which gave the super- intendent of the roads the right to use dirt on the roads from the nearest and most convenient land, to save hauling, and I did so, and I was restrained by the circuit court from taking such dirt. It came up before the judge, and the judge sustained me in that very point, that I had the right to take dirt and use it from the nearest and most convenient land to save hauling. This place was opposite a man's farm, and he was gettin more benefit than anybody else, and he stopped me from getting the dirt, but I got it. 68 AMERICAN ROAD CONGRESS CHAIRMAN PARKER: You are a good citizen of Missouri, and I will say to you that you would also have been upheld in Massachu- setts. MR. PAGE : Tomorrow will be the first anniversary of the American Association for Highway Improvement. We have accomplished a certain amount of work this year, but I do not think our work will be well done until we have affiliated with us the American Road Builders' Association. I have the honor to be a di) ector in that organization, and we have with us here the complete executive committee and the President of the Association. I most earnestly hope, and I speak on the part of the directors of the American Asso- ciation for Highway Improvement, that they will be able to affiliate with us, and I want to invite all the directors of the American Road Builders' Association to be present at the directors meeting of the American Association for Highway Improvement, tomorrow after- noon at three o'clock. There is one other thing I should like to say, and that is that we want the automobilists to be affiliated with us and I wish to extend a similar invitation to any of the directors of the American Automo- bile Association to meet with us and bring about an affiliation. I had the pleasure this morning of meeting Mr. Batchelder, chairman of their executive committee, and I hope he will attend, and any of the other directors who may be present. MR. SMITH (of New Jersey) : I am president of the Automobile clubs; I am doing some work in Florida under the Good Roads Asso- ciation, and also under Mr. Bates. I mention this to show that I speak from all sides. I would like to see every association in the United States that has at heart good roads, affiliated with each other. I love good roads and I hate bad roads, and I wish everybody would adopt that motto, and that every association which is interested in good roads will get together tomorrow and make this general affilia- tion. Let this be a love feast. I have talked with people all through the halls and vestibules and the lobby, "Where do you come from?" "North Carolina, we are doing so and so;" "Florida, we are doing so and so;" "Illinois, we are doing so and so. " We might hold one of the quilting parties they used to have when I was a boy; the old women from all around would come and bring pieces of cloth and sew and talk and gossip, and by the time they were done in the after- ROAD COSTS AND MAINTENANCE 69 noon, they would have a whole quilt. We are making a quilt, every city is a small square and every State is a large square, and we are making a great highway. I hope tomorrow, that the A. A. A., the A. A. H. I., and the X. Y. Z., will all come together, and that every- body that loves good roads will come tomorrow and affiliate with this Association. The Association than took a recess until 2.30 o'clock, p. m. AFTERNOON SESSION Tuesday, November 21, 1911, 2.30 O'clock, p.m. HON. HAROLD PARKER, Chairmen, presiding CHAIRMAN PARKER: The first address of the afternoon will be by Mr. Onward Bates, who has been President of the American Society of Civil Engineers and is an authority whom everybody will recognize. THE RELATION BETWEEN ENGINEERS AND CONTRACTORS ON HIGHWAY WORK ONWARD BATES Past President, American Society of Civil Engineers It goes without saying that we recognize the importance of this meeting. Other speakers emphasize this feature and show how much good may result to our whole nation from the earnestness of our pur- pose and our willingness to work for the cause of good roads. No introduction is therefore necessary, and in the brief space of time which I may occupy, I will try to confine my remarks to the subject that has been suggested to me: "The Relation Between Engineers and Con- tractors on Highway Work." I take it for granted that past and present methods of building and caring for our roads are acknowledged to be unsatisfactory, and that the object of the Association for Highway Improvement is to alter or to abolish these methods, and to replace them with better ones. In other words, we must substitute efficiency and economy for failure and waste. We have, as the result of experience in other classes of public work, demonstrated the success of contract work under the direction of engineers. This method of contract work, supervised by engineers, is as applicable to road construction and maintenance as it is to other works, and it has some special advantages which will be explained later. In the first place, road work should be under the dirction of an engineer; because the kind of work to be done, the quality of the work, 70 ENGINEERS AND CONTRACTORS 71 the amount of it, and the method of doing it, it should be determined by an expert. But, suppose the engineer is not an expert, what then? Do not be influenced by any such supposition. Work from knowledge and employ an engineeer who is a road expert. There are engineers who are road experts, and there will be many such engineers developed as correct methods are adopted for road work. As the demand arises, the supply will arise to meet it. In any case, whether the work is performed under contract, or otherwise, the road engineer is necessary. The road engineer should know just what is needed. He should be able to plan and describe these needs so that they are clearly inter- preted to those who do the work. He must make his plans to con- form to the funds provided to pay for the work. He should possess exceptional executive ability, for in his occupation there is an unusual spread of responsibility for the work itself, and for the number of interests which must be considered. Technical knowledge, good judgment, and tactfulness, are all essential qualities which he is expected to possess. His field of action is most attractive, for the reason that half of his problems are already solved. Experience is principally gained by the study of failures, and a knowledge of what has been so poorly done in the past will teach him what must be avoided in the future. To improve the roads in any specified locality requires first of all a head to plan and to supervise the work to be done. This head, whom I designate as the road engineer, must be responsible for all the work in his district, and since responsibility cannot be disasso- ciated from authority, he should have full authority over the conduct of all the work for which he is responsible to the power that appoints him. The engineer must not be hampered in his work by any other consideration than the performance of his duty as engineer. He should have no affiliations, and should eschew politics, knowing all men only as citizens with a common interest to be served by him. A wo'rd of warning here for those who have the power of appointing the engineer scarcely anything can be more subversive to the public good than to make a political appointment of such an office. The engineer should be chosen as an expert in his line of work, which leads to the conclusion that his office should be an appointive, rather than an elective, one. His appointment should be after careful examina- tion of his qualifications for the office, and this can only be made by an appointing power, which is capable of determining his fitness, and which is responsible for the performance of his duties.

His appointment should be after careful examina- tion of his qualifications for the office, and this can only be made by an appointing power, which is capable of determining his fitness, and which is responsible for the performance of his duties. 72 AMERICAN ROAD CONGRESS In the second place, road work should be done by contract, because if we are expected to improve our roads, we must make a business of road work, and since the contractor is in that business, we need to engage his services. No better argument can be made in support of this statement than to call attention to road work which was not con- ducted as a business, and which was performed by men whose busi- ness was not that of road making. > road contractor should know his business. He should know what constitutes a good road, and how to build it . He should be provided with tools and implements required for road construction and maintenance. If the road contractor follows road building as an occupation, it is expected that he will have such plant as will enable him to execute work of the best character, with economy of cost, in money and time, and that he will have a following of workmen familiar with road making. We may reasonably expect that road work will be done by a competent road contractor with greater economy and despatch than can be attained under a system where a local government undertakes to buy plant and employ men with which to do its own road work. The engineer plans and supervises the work, gives instructions to the contractor, inspects material and workmanship, and makes the contractor's estimates for payment. Contracts should be awarded by the engineer, or upon his recommendation. In general, the engi- neer directs the work and is responsible to the power which appointed him, for the performance of all contractor's obligations. The contractor, on his part, must comply with all the requirements of the contract, and to this end is directly responsible to the engineer. Thus it rests with the engineer and contractor to get the best roads possible with the expenditure of the people's money. It is obvious that they must pull together or the people will be losers. Their relations are defined in the contract for the work. In the ordinary forms of contract for work to be performed, the engineer is vested with full power of directing the operations of the contractor. The engineer makes the estimates of quantities and of values, upon which the con- tractor receives payment. It is his duty to fix the standards for mate- rial and workmanship, to inspect the quality of materials and of work, to accept such as conforms to the contract and to reject such as does not meet the contract requirements. Nearly all contracts give the engineer arbitrary power to decide all questions arising in the per- formance of the contractor's obligations, and most contracts state that the decision of the engineer shall be final and binding on the ENGINEERS AND CONTRACTORS 73 contractor. These powers conferred on the engineer appear to be the outgrowth of experience and are perhaps warranted by expediency. For so long as the engineer is competent and fair, the system works very well, but engineers have the qualities common to humanity and it would be fairer to them if the provisions of a contract confined their decisions within the limits of justice. Experienced contractors some- times find that contracts which they must accept or go without the work give the engineer such an advantage over them, that they attach more importance to the personality of the engineer than to the terms of the contract. Speaking from experience, both as an engineer and as a contractor, I do not favor vesting the engineer with arbitrary power over the contractor's interests. We live under a constitutional government, and contracts between its citizens should preserve the constitutional rights of both parties. A contract which enables one party to work an unjustice upon the other, is contrary to public policy, and whether it be legal or not, it conflicts with the principles which all of us claim as citizens. I believe it is possible to draw contracts which will secure the faithful performance of the obliga- tions of both parties, and will, at the same time, protect the interest of the party at whose expense the work is carried on. Under a general system of road improvement throughout the country, equitable forms of contract will be developed which will supersede forms that are found in practice to be objectionable. Bring together the expert engineer and the competent contractor, and it will be found they can work to- gether in harmony and obtain the best results for the community which employs them. In most cases of trouble between the engineer and the contractor the fault lies with one or the other, or with both of them. It would seem almost superfluous to make the statement that the best form of contract is* that which covers the obligations of both parties in the simplest and plainest terms, leaving out all unnecessary language. And yet it is well to be reminded of this, for many con- tracts for performance of work are so unintelligible that both engineer and contractor find it difficult to decide what are their respective obligations. Specifications for material and workmanship are usually attached to, and form a part of, the contract. The preceding remarks favoring brevity and simplicity in the wording of contracts apply with equal force to the specifications. Instead of trying to include in the speci- fications everything under the sun, it will be better to omit from the contract all items of uncertain and indeterminate character, and this 74 AMERICAN ROAD CONGRESS will avoid the necessity of describing and specifying their value and extent. In the interest of economy and efficiency, the work should be classi- fied and grouped in the most convenient manner for letting it by con- tract. The work should be of such character and volume as will enable the contractor to make favorable /prices. The engineer should also try to arrange the work so that a contractor may work continu- ously through the working season. The expenses of organizing and starting work are understood, and should not be repeated any oftener than is necessary. Changing contractors or employing them at intervals of time, involves what may be called ' 'contractor's terminal expenses," and if these can be avoided there will be a considerable saving in cost, which should be recognized in the contract prices and the saving divided between the parties. Better prices for work, and better service will be obtained from an established local contractor, who, in looking to the work as a means of livelihood, desires to retain in his service experienced workmen and to keep his plant employed, both of which are necessary for economical operations, and he will thus be in a position to make more favorable proposals for the work than when making ventures with scattering bids in various localities, and with unfamiliar conditions. In advocating the contract method of doing road work, I recognize that some work can be more effectively handled by day labor or by special arrangement. There is a distinction between road making and road maintenance. The former may be classed as intermittent work, and the latter as continuous work. Maintenance and repair work will frequently be of such a nature that it cannot be advantageously contracted for, and the engineer must provide for this class of work by day labor, or by some method which is suggested by his experience. In general, it is better to contract for all work which is adaptable to that method. The engineer's operations may cover an extended field and cause him to be unable to personally supervise the work, in which case his inspectors or other assistants must act for him, and they can be better employed in controlling results of work done at the contractor's cost, than in becoming responsible for the value of work done by the engineer's employees who maybe so scattered that the cost of supervision will equal the wages paid to the work- men. Another reason for avoiding the direct employment of work- men, is that it means the purchase of tools and implements for the workmen, and this will always be unprofitable unless there is suffi- ENGINEERS AND CONTRACTORS 75 cient work to wear them out. There is scarcely a worse investment than contractor's outfit which is not employed. It is not uncommon for a contract to specify that the contractor shall guarantee his work for a certain period of tune, sometimes reaching into years. There may be cases where a contractor's guar- anty is justified, but it is a questionable practice. Competent engineering will require and secure good work. When a contract is completed, the engineer should know that the contractor has given the full value of work specified in the contract, and he should be in a position to pay that value in full. The engineer's employment should be continuous. He should be a permanent officer of the local govern- ment, responsible to his superiors for construction and maintenance of the roads. This responsibility, as has been stated, should clothe him with the authority necessary to secure the ends he is employed to attain. Since the engineer is the official who makes the plans and controls the execution of them; while the contractor works under his instruc- tions, subject to the terms of the contract, any suggestions as to road making should be addressed to the engineer, who will communicate to the contractor as much of them as is necessary hi carrying out the work. I purposely avoid mentioning details of contracts, plans and specifications, all of which the engineer must fit to the particular problems he is called on to solve, but in a general way, I venture to suggest some of the elements of road engineering necessary to be observed in his practice. He must always maintain an equilibrium between the amount of work he plans to carry out, and the funds available to pay for this work. The kind and amount of work will be limited by the sum appropriated for its cost. He must decide whether the limitation shall be placed on the kind or the volume of the work. As a general pro- position the character of the work should be uniform. To secure this he may have to sacrifice his ideals and fit the character to the circum- stances controlling the case. The efficiency of a road is determined by the tonnage hauled. For a given distance of haul, unless the road is of uniform quality, the haul will be limited by the worst portion of the road. There is, therefore, such a thing as making the road or at least a portion of it too good, if the funds are not within sight to bring the whole distance to the same good quality. In a rich and populous state where the people have awakened to the necessity for good roads and contemplated the expenditure of 76 AMERICAN ROAD CONGRESS more than $100,000,000 to secure that end, it is very well to say, "we will build no cheap roads," and to fix a standard of $5000 or $6000 per mile for construction. On the other hand, hi the case of a State with a population less hi density and with a much smaller provision of funds, and yet -
