Improved RD models for sealed granular and asphalt pavements are needed. Pavement performance history data from state road authorities and New Zealand (SRAs) were used for calibrating RD models. The calibration and refinement of RD models is expected to continue up to 2007/08. This report presents the outcome of using an objective method to estimate pavement deterioration from the performance history of the Victorian, Queensland, Tasmanian, South Australian and New Zealand sealed and asphalt road network. The objective method of estimating deterioration and calibrating HDM-4 roughness, rutting and cracking models is presented. It is recommended that this approach be used to analyse performance data from other SRAs in 2007/08 for RD model calibration.
