The report provides a summary of works undertaken during the period 2017–18 for Austroads project AT1064 – Long-term pavement performance (LTPP).

The weakest element of Pavement Management Systems currently in place or being developed in Australia is the prediction of pavement performance. The use of long-term pavement performance (LTPP) monitoring results will improve our understanding of the performance of pavements and lead to cost savings and more appropriate construction and rehabilitation practices.

To address this issue, Austroads participated in the US Strategic Highway Research Program (SHRP) in 1994 by setting up its Australian LTPP project to monitor a range of test sections of different pavement types, including sealed granular materials, asphalt and concrete, under different traffic and climatic conditions.

This report is the last of a series of annual summary reports that typically covers all activities carried out during the year and monitoring results.
