The projected AADT during the first year of operation is 3900 (both directions). If the traffic growth rate is estimated at 3% and the CBR of the subgrade is 7.5, determine the depth of a full-asphalt pavement using the AASHTO method and n = 20 years. The resilient modulus of the asphalt (EAC) is 320,000 lb/in2. Assume mi for the subgrade is 1 and the percent of traffic on the design lane is 42%, pt = 2.5 and SN = 4. Use a reliability level of 90%, a standard deviation of 0.45, and a design serviceability loss of 2.0.

The predicted traffic mix of a proposed four-lane urban non-interstate freeway: Passenger cars = 78% Single-unit trucks 2-axle, 5,000 lb/axle = 12% 2-axle, 9,000 lb/axle = 4% 3-axle or more, 23,000 lb/axle = 3% Tractor semitrailers and combinations 3-axle, 20,000 lb/axle = 3% What will be an ideal response?
