This report presents the summary of project activities conducted in 2005/06. A number of suitable sealed granular pavement sites were identified across Australia for inclusion in the LTPP study. Interim WE models were developed. An improved revised method was used to calibrate HDM-4 RD models for roughness, rutting and cracking to suit Victorian, South Australian and Tasmanian local conditions. An attempt will be made to employ the revised method for the data from other Austroads Member Authorities' (SRAs) road network.
