A flexible pavement is known to have a structural number of 4.0 and a soil resilient modulus of 10,000 psi. If a pavement structure is to be designed for a life of 15 years, a reliability of 95% and an overall standard deviation of 0.35, how many passes of a design vehicle with a 18,000 lb single axle and a 34,000 lb tandem axle can be driven on the pavement per day?
