This report presents the summary of project activities conducted in 2006/07. A number of suitable sealed granular pavement sites were identified across Australia for inclusion in the LTPP study. An improved revised method was used to calibrate HDM-4 RD models for roughness, rutting and cracking to suit Victorian, South Australian, Tasmanian, Queensland and New Zealand local conditions.
