A flexible pavement at an access road to a sportsstadium parking lot is designed with a 4-inch sand-mixasphaltic concrete surface, 5-inch aggregate bituminousemulsion base, and a 10-inch crushed stone subbase.There are 95 scheduled baseball and football games atthe stadium per year. The access road to the parking lotis three lanes in each direction (conservativelydesigned). The pavement was designed for recreationalvehicles with one 20K single axle and one 20K tandemaxle. There are 9,000 recreational vehicles estimated ateach event. Given that drainage coefficients are 1.0, theoverall standard deviation of traffic is 0.45, reliability is90%, and the soil's resilient modulus is 15,000 lb/in2,how many years will the access road last if the initialPSI is 4.0 and the terminal serviceability index is 2.5?
