A rigid pavement is being designed with the same parameters as used in Problem 4.5. The modulus of subgrade reaction is 300 lb/in? and the slab thickness is determined to be 8.5 inches. The load transfer coefficient is 3.0, the drainage coefficient is 1.0, and the modulus of elasticity is 4 million 1b/in?. What is the design modulus of rupture? (Assume that any parameters not given in this problem are the same as those given in Problem 4.5.) 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, and 200 tandem axles at 40,000 lb each. The highway was designed with 4 inches of HMA wearing surface,
