Polished aggregate friction value (PAFV) tests are used by most jurisdictions in Australia to determine the resistance of aggregates to the polishing action of vehicle tyres on the road. Two versions of the PAFV test are used in Australia: the…
This report describes studies of the effects of test conditions on vertical polished aggregate friction value (PAFV) results and the results of a proficiency study which was conducted to determine a preliminary PAFV value for UK aggregate. The…
Cutting solvents have been traditionally added to binders used in sprayed sealing in Australia and New Zealand to ensure that effective adhesion occurs between binder and aggregate. Recent Polymer modified binder (PMB) sealing failures, which have…
The work described in this report determines updated cutter level recommendations for S10E and S20E binders. Studies were also conducted to investigate the relationship between the contact angle of water on films of bitumen and PMB binders, and…
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…
