Modern Methods of Highway Maintenance

Abstract

The systematic maintenance of county roads only has been discussed, hovvever the genercl principals and methods outlined are applicable to city streets in many respects. The discussion has been outlined and classified so that the methods peculiar to each type of surface are separated. The problems of maintenance, howrever, are often similar in which cases references have been made to other sections of the subject. The testing of materials used has not been discussed at length as this phase of Highway Engineering is more closely allied to construction work. In maintenance the materials used are those that are most easily obtained locally together with certain standardized manufactured products. Preliminary to the discussion of maintenance of the various types of surfaces a short description of the method of construction has been given. This has been done to better bring out why certain maintenance operations are carried out and are necessary. [From Introduction]
