Question

For the pavement system with the following properties, Design an appropriate structure .for this pavement Top layer: HMA with E = 400,000 psi, layer coefficient = 0.41., and min thickness 4 inches Intermediate layer: Base coarse with E = 20,000 psi, layer coefficient = 0.10, drainage .coefficient = 0.8, and min. thickness 6 inches Bottom layer: sub-base coarse with E= 10,000 psi, layer coefficient 0.09, and drainage coefficient = 0.8 Subgrade with Mr = 5000 psi If the predicted ESAL = 8.0 x106, R= 99%, .So = 0.50, and OPSI = 2.0 ,SN1 = 1.20 SN2 = 1.9, and SN3 = 3.1 Find: The thickness of the Asphalt concrete
