Asphalt pavements are a major component of the Australian and New Zealand road networks. Road agencies in Australia and New Zealand have been putting great efforts to produce pavements which perform and are long-lasting. This has led to the…

This report describes research work into the development of a new test method utilising the dynamic shear rheometer (DSR) to conduct consistency 6% at 60 

The increasing pace of change of technology brings considerable promise of more data, of a higher quality, captured for a lower cost. This has the potential to improve the asset management of roads by enabling better decision making and providing a…

This report identifies and evaluates technology solutions that meet asset management needs relating to road pavement performance. The increasing pace of change of technology brings considerable promise of more data, of a higher quality, captured for…

This report provides a review on surface characteristics in relation to traffic noise and long-life surfacings. For the conventional asphalt surfacings in general road construction practice, the selection of mix type and size would define two most…

Austroads Project AT1064 Long Term Performance Monitoring and Model Development was initiated in 1994/95. The project was reviewed in 2003 and later in 2007 by GP Youdale Consulting Engineers to assess the project’s program and progress and, if…

The Elastometer is the key testing instrument for PMB specifications in Australia. The Elastometer operating software and data acquisition system were developed in the 1980s, originally to run under DOS and later upgraded to Windows 3.1. This…

This Pavement Work Tip discusses some of the factors that affect riding quality, and how to ensure a smooth riding asphalt pavement.

Polymer modified binders (PMBs) can provide improved service performance over normal bitumens in demanding situations. However, a number of field problems have been experienced with PMBs and some of these have been attributed to property changes…

A major study was undertaken to determine relationships between binder rheological properties and the rut resistance of asphalt mixes, as indicated by the laboratory wheel tracking test. Twelve binders, including three bitumens, a Multigrade binder…
