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 study investigated whether the segregation propensity of a polymer modified binder (PMB) during hot storage affects its performance on the road.

The Australian PMB specification currently includes a segregation test which determines whether the…

This report presents the findings from the first year of a three year Austroads study which aims to maximise the re-use of reclaimed asphalt pavement (RAP) in new asphalt product. The objective of this first year of study is to improve the…

This report presents the results of a literature review and laboratory study which was conducted as part of the development of a new-long term ageing (durability) test for bituminous binders used in sprayed seals in Australia.

The literature review…

Bitumen, an important component used in road construction in Australia and New Zealand, is manufactured from a finite, non-renewable crude oil resource. A number of commercially available alternative binders and bitumen extended binders have been…
