A 3-inch hot-mix asphalt (HMA) overlay is placed on the pavement as shown below. The concrete has a modulus of elasticity of 4,000,000 psi and the HMA has a modulus of elasticity of 700,000 psit Assume that there is full bonding between the layers and that the moment remains the same after overlay. The decrease in the maximum tensile stress
