5. (a) For the full depth AC pavement designed in Problem (b), calculate the maximum tensile bending strain (exc) in the AC layer under a single tire load P=18,000 lb using the figure provided below and axis symmetry condition of wheel load. Use a circular tire pressure of q-64 psi. Assume the Poisson's ratio as 0.5. If you did not solve Problem 4(b), assume the AC layer thickness as 10".
