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 S%-0.35 and APSI=2.0. E1=500000 psi D1 E2= 20000 psi D2 HMA surface Untreated base course Sand gravel suhhase F3-150000 psi D3
