A SIMPLIFIED RATIONAL DESIGN METHOD FOR FLEXIBLE ROAD PAVEMENTS

A simplified, approximate version of a recently developed rational design method is presented, which uses a somewhat modified version of Odemark's equivalent layer theory as a substitute for exact multi-layer elastic theory. The accuracy of the method is adequate for practical purposes except possibly where failure occurs due to fatigue in thin bituminous layers. It should be particularly useful for exploring the performance of alternative pavement configurations and mix designs. The method is readily implementable on a microcomputer. In fact, a computer program for this purpose has been written in BASIC. A listing of it is included in the report. (TRRL)
