This report presents the proposed future directions for long-term pavement performance (LTPP) studies in Australasia. The proposed way forward is based on the results of a 2017 survey directed to the LTPP Project Steering Group (PSG) and Assets Task Force (ATF) with the objective of assessing their views regarding the future direction and management of the project together with a wider perspective on the value of Australasian LTPP data.
