This Pavement Work Tip details the production and paving of EME2, a high modulus asphalt produced with a very hard paving grade bitumen and a high binder content.

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…

The ban on the export of recycled waste plastic by the Australian government has led to interest in the use of recycled waste plastic in road surfacing applications. Austroads has published a report, Interim guidelines for the use of recycled waste…

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 

This Pavement Work Tip provides a guide to the light application of bituminous binder to an existing asphalt or spray seal surface to increase the binder level on the surface and prevent aggregate loss.

As a result of the ban on the export of recycled waste plastic, there is increasing interest in repurposing recycled waste plastic for use in road surfacing applications. There is no guide for this purpose and until such time as a guide is available…

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/…
