Excerpt from Highway Construction, Vol. 1: Instruction PaperThe object of a road is to provide a way for the transportation of persons and goods from one place to another with the least expenditure of power and expense. The facility with which this traffic or transportation may be conducted over any given road depends upon the resistance offered to the movement of vehicles: This resistance is composed of: (1) resistance offered by the road way, which consists of (a) friction between the surface of the road and the Wheel tires, (b) resistance offered to the rolling of the wheels occasioned by the want of uniformity in the road surface or lack of strength to resist the penetrating efforts of loaded wheels, (c) resistance due to gravity called grade resistance (2) resistance offered by vehicles, termed axle friction, and (3) resistance of the air. The magnitude of each of the components has a wide range, varying with the kind and condition of the road and its surface, the form and condition of the vehicle, the load, and the speed.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
