- A six-lane concrete roadway is being designed for a metropolitan area. This roadway will be constructed on a subgrade with an effective modulus of subgrade reaction k of 200 lb/in^3. The ESALs used for the design period is 6.0×10^6. Using the AASHTO design method, determine a suitable thickness of the concrete pavement (to the nearest 1/2 inch), provided that the working stress of the concrete to be used is 600 lb/in^2 and the modulus of elasticity is 6×10^6 lb/in^2. Assume the initial serviceability is 5.0 and the terminal serviceability is 2.0.
