It is required to design a collector road pavement in an urban area composed of 3
layers with different material and resilient modulus values as shown in Figure 1.
Given, ESAL=1.0*10°, drainage quality is good. Less than 25% of the time the
pavement will be exposed to moisture levels approaching saturation. Determine the
thickness of the pavement courses layers. Assume So-0.35 and APSI=2.0.
