What is the formula for Olders Theory in Rigid Pavements

An interstate highway pavement composed of an HMA surface course, a cement treated base course and a sand-gravel subbase is to be designed for an ESAL of 2 * 10^6 . The quality of drainage is considered poor with more than 30 % of time the pavement will be exposed to moisture levels approaching saturation. The material properties are summarized below: effective roadbed resilient modulus = 5500 psi, resilient modulus of subbase = 15000 psi, resilient modulus of cement-treated base is 60,000 psi and resilient modulus of HMA = 4.0 * 10^5 psi. Determine the thicknesses of the surface, base and subbase courses required by assuming a minimum thickness for HMA.
