This report provides a brief state-of-the-art review of current traffic speed deflectometer (TSD) practice based on information gained from attending the deflection at road traffic speed workshop held in the UK in June 2012.
The current state of…
Bitumen, an important component used in road construction in Australia and New Zealand, is manufactured from a finite, non-renewable crude oil resource. A number of commercially available alternative binders and bitumen extended binders have been…
This report provides a worked example for developing skid resistance investigatory level guidelines.
The worked example is sourced from Main Roads Western Australia (MRWA) and relates to texture measurement as a surrogate for skid resistance. A…
This report presents the summary of project activities conducted during the 2011/12 season, including a summary of the LTPP/LTPPM pavement condition survey results, a brief summary of the development of probabilistic road deterioration (RD) models…
This report details the work undertaken in the first year of the three year Austroads project Improving the Estimation of the Cost of Accelerated Road Wear due to Possible Increases in Axle Mass Limits. In 2011-12 the project identified road sites…
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 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…
This report improves the current approach to cost allocation, develops incremental pricing, and develops direct user charging. This report includes analysis of the relationship between road use and expenditure without considering road
