A rural principal arterial is expected to carry an ESAL of 0.188 x 106 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 15,000 lb/in2, design a suitable pavement consisting of a granular subbase with a layer 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 400,000 lb/in2. Assume all mi values = 1, the percent of traffic on the design lane is 47%, and SN = 4. Use a reliability level of 85%, a standard deviation of 0.45, and a design serviceability loss of 2.0.
