Austroads established its long-term pavement performance (LTPP) project in 1995. Over the last few years, a significant number of sites have been removed from the study due to pavement rehabilitation and road improvement programs.

This report provides details of two replacement test sections in South Australia: the Port River Expressway (PRExy), Port Adelaide; and the Dukes Highway, Cooke Plains.

The report contains detailed information about the sites including:

  • surface deflection, longitudinal and transverse profile, and visual assessment data collected during initial fieldwork in November 2013 as part of the 2013–14 LTPP monitoring program, and
  • traffic data, pavement composition, historic pavement performance and maintenance activities, provided by the South Australian Department of Planning, Transport and Infrastructure (DPTI).
