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 

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 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).

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 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 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…
