The laboratory characterisation of cemented materials for road pavements has recently been completed in Austroads Project TT1359 Cost-Effective Structural Treatments for Rural Highways. This project concluded there is a need for a substantial revision to the thickness design procedures for cemented materials as provided in Austroads Guide to Pavement Technology – Part 2: Pavement Structural Design (Austroads 2010). This report provides a research strategy for this revision. It reviews the origins of the current design procedures, results of past and recent laboratory and accelerated loading trials on cemented materials modulus and fatigue. Based on this review a research strategy is proposed to deliver the revised Austroads procedures.
