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…

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 14 March 2019, provides an update on the Austroads’ project to develop the data to support the Heavy Vehicle Road Reforms.

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 webinar, presented on 31 January 2019, provides an overview of Austroads' study that proposes a ride quality index of roads for heavy vehicles, a heavy vehicle equivalent of the International Roughness Index (IRI) for cars.

Overseas research has suggested that asphalt fatigue endurance limit may exist, where applied strain is sufficiently low no fatigue damage accumulates in the asphalt as the rate of asphalt healing exceeds the rate of damage accumulation. The…

This report documents the results of an Austroads project to identify the asset management needs and level of service (LOS) requirements of future non-freight road users.

Preliminary work documented the relationship of this project to other Austroads…

The use of recycled asphalt pavement (RAP) in asphalt mixes provides a vital basis for sustainable development. Maximising the re-use of RAP in its highest value application, as new asphalt product, has significant economic and environmental…

This report documents the outcomes of surveys of road freight drivers, operators and road infrastructure managers to better understand their asset management level of service (LOS) requirements.

The survey responses identified three primary road…
