What aspects of highway policy should each engineer take into account? What can the applied loads cause? What is the maintenance of the road? What factors should be avoided during road designing?

1. Each highway engineer has unavoidable contact with three broad aspects of highway policies: development, operational and regulatory. The development policy deals with the construction, maintenance and operation of the highways. The operational policy concerns operation of the vehicles, because it greatly results in planning and design of the roads. The regulatory policy mainly concerns general regulation of transportation.

2. The roadway structure is the subject to the wheel loads of motor vehicles, which result in deflection of the surface and the underlying layers. The applied loads cause roughening and cracking of the pavement and in some cases can lead to the failure of road structure. In such cases the repair is needed. But it is much better to maintain the road properly.

3. Highway maintenance involves patching, filling ruts, removing surface corrugations, pouring cracks, blading surfaces, cleaning ditches and culvets, repairing bridges and fighting floods. It also includes operation of the highway as a safe, efficient and pleasing link in the nation’s highly important transportation system. This adds such duties as erecting signs and traffic control, painting traffic stripes, mowing grass and weeds, clearing away trash, removing snow, spreading cinders and other services which the public has come to expect.

4. The students of the faculty also study the designing of roads. The key-stone of modern highway design is to make the suitability of the highway for vehicle and driver as nearly perfect as possible. The designing of roads should be directed to eliminating accidents. The alignment should be the best obtainable when topography and urban development are considered. Sharp horizontal curvature should be avoided at the end of long tangents where surprise factor would cause many accidents. It is axiomatic that the longer the tangents, the flatter should be the connecting curve.
