This report examines the viability of using recycled plastics in asphalt and sprayed seals by Australian and New Zealand road authorities. The report presents the findings of a literature review, including case studies of local and overseas road…

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 Pavement Work Tip details the profiling or cold planning of asphalt pavements, a process that removes uneven areas of pavement to allow the placement of  new, uniform surface.

This report details the first year of a three-year Austroads project to transfer French Enrobés à Module Élevé Class 2 (EME2) technology to Australia. EME2 technology offers the prospect of reduced asphalt thicknesses for heavy duty pavements, and…

Polymer modified binders (PMBs) are increasingly used in road construction as they provide enhanced performance properties compared with conventional bitumen. Even though PMBs show enhanced service properties, they may show degradation or changes in…

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

Among the number of test methods reviewed and…

The Guide to Pavement Technology Part 4B: Asphalt provides an introduction to the nature of asphalt as a material and its application in road pavements.

This report documents an asphalt deformation trial established over a 1200 m length of Dandenong Road in Melbourne. The trial aimed to validate the wheel tracking used in the Austroads mix design method. The trial involved the placement of seven…
