Problem 5:- Design the pavement for a highway principal arterial road consisting of an asphalt concrete surface, a crushed gravel base, and a granular sub-base using the 1993 AASHTO design chart (Figure 8.22). The cumulative ESAL in the design lane for a design period of 10 years is only 69 for the peak hours of (7:00-8:30 AM and 2:00-3:30 PM). The area has fair quality drainage with 25% of the time the moisture level is approaching saturation. The effective roadhed soil resilient modulus is 10 ksi. The sub-base has a CBR value of 50, the resilient modulus of the base is 30,000 lb/in², and the resilient modulus of the asphalt concrete is 4.0 x 105 psi. Assume a reliability level of 90%, So of 0.40, Po of 4.6, and Pt of 3.0.
