MECHANISTIC PAVEMENT DESIGN FOR ARIZONA

The report summarizes procedures used to develop a methodology for the structural design of asphaltic pavements in Arizona. The design details are for rural interstate highways and consider (a) traffic evaluation, (b) material characterization, and (c) environmental effects. The basic procedure uses the Chevron Computer Program to calculate stresses and strains of selected points in a three-layered system and subroutines are utilized to determine the fatigue life for trials of assumed surface and unbound base thicknesses. The utility of the design procedure is enhanced by the establishment of equivalent axle load factors and entering into design charts; therefore, eliminating the need of a computer. Examples of the procedure employing the charts are presented. (Author)
