The Austroads Network Operation Planning Framework (the Framework) was developed in 2009 however it is not widely used by road agencies. This research aimed to understand each road agency’s approach and consider how the Framework could be improved…

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 Pavement Work Tip is a practical guide for restoring texture to bleeding or flushed surfaces by applying additional aggregate with the assistance of chemical solvents.

The objective of Austroads Project NS1203 (Estimating Road Network Congestion and Associated Costs) is to develop a procedure to calculate delay and associated congestion costs by making use of directly measurable traffic data. Network performance…

Part 4J of the Guide to Pavement Technology provides information and guidance on: the classification and description of source rocks

This report reviews the tools that monitor, measure and evaluate the performance of the road network, for both arterials and freeways. The interest in measurement and evaluation tools for the overall network is mainly driven by the need to operate…

This Austroads project was initiated to enable road authorities to develop a better understanding of how various traffic management tools and proposed operational changes to the road network affected the performance of the entire road network, with…
