A flexible pavement is constructed with 5 inches of sand-mix asphaltic wearing surface (a = 0.35), 9 inches of dense-graded crushed stone base (a = 0.18), and 10 inches of crushed stone subbase (a = 0.11). The base has a drainage coefficient of 0.90 while the subbase drainage coefficient is 1.0. Determine the structural number of the pavement.
