Q3. A pavement structure is comprised of the following layers: 5.75-inch asphalt concrete surface, E =400,000psi; 23.0 inches of granular base, E=20,000 psi, and a subgrade having an E =10,000psi. All layers are assumed to have u =0.5. Calculate the horizontal tensile strain at the bottom of the asphalt concrete layer and the vertical compressive strain at the top of the subgrade layer under the centerline of a 40,000 pound wheel load, 150 psi pressure. a P=40,000 111 p=150psi h1=5.75 in, Ej=400,000 psi, Hi=0.5 h2=23 in, E2=20,000 psi, M2=0.5 h3=4 Ez=10,000 psi, M3=0.5
