This study examines the value and need for network-level pavement deflection data to support road asset management decisions. The outcomes of the study provide critical input to decisions to undertake network-level strength assessment across…

The purpose of this report is to identify new technologies that are potentially useful for asset managers and develop guidelines for the application of selected new technologies for asset/risk management. This report covers the first stage of the…

Claims for compensation brought by road users against road authorities remain a significant issue across Australia. Further, the claims environment varies between jurisdictions (states and territories) and differences have been found in the…

This report has developed a new index, the Heavy Vehicle Roughness Band Index (HVRBI), as a measure of ride quality for heavy vehicles. The HVRBI is intended for use by road asset managers as a trigger to initiate pavement intervention works…

This report develops approaches that estimate the marginal cost (MC) of bridge wear for heavy vehicle usage and estimates the availability and reliability of the data needed to use these approaches. Two approaches were examined. The first was an…

This study obtained an indication of the proportion of Australian commercially manufactured polymer modified binders (PMBs) liable to segregate, identifed suitable tests to measure segregation propensity and proposes measures to help prevent or…

This report is an investigation on the development of the performance relationships used in the 2002 AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG). The primary objective of this investigation was to see if these relationships could be…

This report explores the dynamic forces that heavy vehicles apply to road pavements and the effects that these forces have on pavement performance. The research focussed on identification of accurate and cost effective means to quantify dynamic…

This report is a scoping document aimed at establishing how road deterioration (RD) models can be developed on a probabilistic basis. Deterministic RD models provide an average estimate to a future condition which is not necessarily likely to be…

Austroads Project AT1064 Long Term Performance Monitoring to Develop Consistent Performance Models has been running since 1994-95. A review of the analysis of US long term pavement performance (US LTPP) data used to validate the performance…
