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…

Flexible granular pavements protected by sprayed seal surfacings are the backbone of the Australian and New Zealand road networks. Road agencies in Australia and New Zealand have therefore been focused on producing quality, long-lasting sprayed seal…

This report presents the findings of site inspections and binder ageing performance studies associated with two Austroads sprayed seal trial sites constructed near Coober Pedy, South Australia and Cooma, New South Wales. These trials were…

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 webinar, presented on 31 October 2018, provides an overview of the key changes to the Guide to Pavement Technology Parts 4F and 4K, and the significant advances in the areas of binder specifications and sprayed seal design.
