Traffic for a future roadway is projected to be AADT = 15000 vehicles. Vehicle distribution and thecorresponding ESAL factors are given in Table 1.

1. Using a growth factor of 3%, estimate traffic in the design lane, in ESALS, for a design life of 30years. 2. The subgrade soil is a high plasticity clay (CH). The available base and sub base materials have R-Values of 75 and 50, respectively. Design a conventional flexible pavement structure using the 1 993 AASH TO method. Clearly state all assumptions made.
