TRUCK CHARACTERISTICS AND PAVEMENT EFFECTS

A project is reported which was intended to develop engineering knowledge which could be used in the design and construction of new highway pavements and bridges, and in the preservation and improvement of existing pavements. It was also intended that the findings be used, in conjunction with data from other research, toward the ultimate goal of determining an optimum economic balance between vehicle operating costs and the costs of highways. The relationship between axle loads for both single and tandem axles and the number of equivalent single axles for flexible pavements is discussed, and an analysis procedure to provide a means of easily comparing the effect of different truck combinations at different weight levels is described. Other aspects covered here include a Present Serviceability Index, the effect of pavement thickness, the effect of various pavement design strategies, and the relationship between payload and the ton mile.
