Question: A two - layer pavement system has an asphalt concrete elastic modulus of 1 0 0 , 0 0 0 psi and a subgrade elastic

A two-layer pavement system has an asphalt concrete elastic modulus of 100,000 psi and
a subgrade elastic modulus of 20,000 psi. A single wheel has a circular contact area with
an 8-inch radius, and 100 psi tire pressure is applied on the surface of the asphalt
concrete. The asphalt concrete is 6-inch thick. How much is the maximum vertical
interface stress?
