4.5 for reference:
A flexible pavement was designed for the following daily traffic with a 12-year design life: 1300 single axles at 8000 Ib each, 900 tandem axles at 15,000 1b each, 20 single axles at 40,000 Ib each, and200 tandem axles at 40,000 lb each. The highway was designed with 4 inches of HMA wearing surface,
