Recognising the importance to pavement designers, asset managers and policy makers of an improved understanding of the relationship between different multiple axle group loads (single, tandem, triaxles, etc.) and road pavement performance, Austroads…

This research study investigates – using a combination of current research, laboratory characterisation and field trials – improved methods for assessing the pavement damage caused by different multiple axle group loads, and to develop a framework…

This report presents the test results of bitumens used across different states in Australia. This database will be useful in identifying possible trends in properties associated with recent changes in the manufacture of Australian bitumens and…

This report is the second in a series which examines the properties of Australian bitumens from around Australia. Thirty-one bitumens from around Australia were subjected to a range of test procedures. These included viscosity measurement at a range…

A significant factor contributing to the establishment of Australia’s large network of surfaced roads has been the successful application of sprayed sealing technology, including the selection of treatments, design of the treatments and application…

This report reviews the current design and application practices for primes and primerseals. Primes and primerseals play an important role in achieving a successful surfacing as they form the basis for the performance of future treatments. Any…

Austroads Project No: TT1358: Review of Structural Design Procedures for Foamed Bitumen Pavements proposed a method for the thickness design of foamed bitumen to be adopted in principle by Austroads. Foamed bitumen is a mixture of hot bitumen, water…

Some recent problems with polymer modified binder (PMB) seals have been attributed to lack of initial adhesion of the binder to the sealing aggregate. This suggests that higher levels of cutter than those given in an Austroads Guide may be necessary.…

The objective of this project was to define a relevant, feasible and comparable set of network performance indicators (NPIs) that can be used for benchmarking asset management performance across member authorities (MAs) based on a review of existing…

This report provides a review of research and developments in skid resistance measurement methods. The objective is to provide up-to-date information on the major issues (e.g. variability) involved in skid resistance measurement.
