Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design provides advice for the investigation of existing sealed road pavements and the selection and design of pavement strategies/treatments. It covers pavement investigation,…

This study investigated the relationship between cutter oil properties and sprayed seal performance so that this information could be used as a basis for updating Australian Standard 3568. AS 3568 specifies the properties of four different types of…

New methods of using pavement deflection data were developed in the context of pavement structural rehabilitation treatment design. The project focused on two main components. The first was to assess the potential use of traffic speed deflectometer…

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…

Rollover crashes are an undesirable outcome in a substantial proportion of casualty crashes on high-speed roads. Rollovers are especially over-represented in run-off-road crashes due to their direct interaction with the roadside geometry. This…

This webinar, presented on 22 August 2019, provides an overview of the key changes to the Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design and the significant advances in the thickness design of structural treatments for…

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).

Heavy vehicle rest areas (HVRAs) are provided to help heavy vehicle drivers manage fatigue and comply with driving hours regulation. To aid road managers in this task, Austroads has produced 

This webinar, presented on 11 July 2019, provides an overview of an Austroads project that compared the test properties of seven commercially available cutter oils with their sprayed seal performance.

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/…
