A road with estimated 15 million ESAL for both directions after 20 years will be constructed on a subgrade. The CBR of the subgrade was obtained at 24% with standard deviation of 5% (85% probability). Determine the subgrade class and combined thickness of the wearing and binder courses with stabilized base using ATJ5/85 (2013).

Question 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.

The maximum wheel load that the pavement could carry is 120 kN. If the contact radius of the wheel is assumed to be 250 mm, and subgrade bearing capacity is equivalent to 0.24 Megapascals, calculate the subgrade layer thickness of the flexible pavement in mm using the 45-deg cone pressure distribution method.
