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…

This report presents the results of a research project commissioned by Austroads to investigate whether the currently used Australian general-purpose (GP) cement which complies with AS 3972, and which may contain up to 7.5% limestone as a mineral…

This webinar, presented on 1 October 2019, provides an overview of the causes and contributing factors behind road crashes in regional and remote areas, and strategic guidance to identify the best approaches to eliminate harm.

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 note provides information to answer commonly asked questions to assist leadership of change for improved road safety. The Safe System is internationally regarded as the best practice approach to road safety. While Australia and New Zealand have…

In 2016 Austroads partnered with member agencies to deliver a series of 15 workshops to disseminate and explore the findings of Austroads Safety Projects: Translating Safe System Infrastructure Research and Knowledge into Practice (SS2016),…

Road crash fatality rates continue to be unacceptably higher in regional and remote areas than major cities. This report provides a comprehensive investigation of the causes of road crashes in regional and remote Australia and gives strategic…

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).

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/…
