Public Works Department (PWD) received a complaint from the traffic user on the increasing number of pavement deformations such as potholes and crocodile cracks at Jalan Ayer Dalam, Petaling Jaya, Selangor. A site investigation conducted by the PWD revealed that at 5 cm below the center of the tire load, a deflection of 0.889 mm was detected due to a wheel carrying a 30 KN load. The contact radius is measured at 13 cm and the Poisson ratio is 0.5. In order to analyse the pavement's performance, you are requested to determine the pavement's modulus of elasticity.
