This report brings together five years of research into the modulus, strength fatigue characteristics of cement treated granular materials as used in road pavements. Laboratory procedures used to prepare, cure and test materials for flexural modulus, flexural strength and flexural fatigue behaviour of cemented material beams are reported together with the test results.

Based on the laboratory results, a framework for the revision of the Guide to Pavement Technology Part 2: Pavement Structural Design(AGPT02-12) has been suggested and the proposed revised text of the Guide has been prepared.
