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

This test method sets out the procedures for the measurement of the stress ratio of binder samples under specific conditions using the dynamic shear rheometer (DSR). A major failure mode of sprayed seals and asphalt pavements is fatigue cracking of…

This report identifies road design improvements to better cater for the safe passage of heavy vehicles through railway level crossings.

This test method sets out the procedures for the ageing treatment of bitumen samples under specific conditions using the Pressure Ageing Vessel (PAV), and also the determination of the complex viscosity of treated samples under specific conditions…

This report provides a compendium of recent and robust evidence on the relationships between twenty key geometric design criteria and safety outcomes.

The project critically reviewed quality research sources to identify crash modification factors…
