The freight industry is critical to the economy, and for many sectors it is heavy vehicles that underpin freight movements and prosperity. The average age of trucks in Australia and New Zealand is among the highest in the developed world. The oldest…

Polymer modified binders (PMBs) are prepared from mixtures of polymers, additives and bitumen selected to achieve their required properties. Some of these binder systems can segregate leading to variations in measured properties and in some…

This report investigates policy options for reducing the harmful effects of the oldest trucks operating on Australian and New Zealand roads. Aged trucks impose a financial burden on the community through their effects on human health and the…

This test method sets out the procedure for determining the rubber content of a crumb rubber modified binder using a Soxhlet extraction apparatus. This test method is applicable to crumb rubber modified binders used in constructing and maintaining…

This report presents the results of a field validation study conducted as part of the development of a new long term ageing test for polymer modified binders used in sprayed seals in Australia. Unaged samples of binders were collected during the…

This webinar, presented on 8 August 2019, provides an overview of an Austroads project that developed a new sprayed seal binder cracking test and compared the performance of polymer modified binders (PMBs).

Heavy vehicle rest areas (HVRAs) are provided to help heavy vehicle drivers manage fatigue and comply with driving hours regulation. To aid road managers in this task, Austroads has produced 

The Australian polymer modified binder (PMB) specification (AGPT/T190) currently requires different binder grades to be used in sprayed sealing and asphalt applications. This study compared the sprayed seal performance of PMBs representing four AGPT/…

This specification framework outlines the requirements for PMBs and crumb rubber modified binders for use in both sprayed sealing and asphalt applications.

This webinar, presented on 14 February 2019, provides an overview of the Austroads Guidelines for the Provision of Heavy Vehicle Rest Area Facilities.
