A rural principal arterial is expected to carry ESAL of 0.188x10^6 during the first year of operation with an expected annual growth of 6% over the 20-year design life. if the subgrade has a resilient modulus of 103,500kN/m2, design a suitable pavement consisting of a granular subbase with a layer of coefficient of 0.13, a granular base layer with a layer coefficient of 0.14, and an asphalt concrete surface with an elastic modulus of 2760,000kN/m2. assume all mi values = 1 and the percent of traffic on the design lane is 47%. assume the design seviceability loss is 2.0, reliability level of 90%, standard deviation of 0.45, and SN=4
