Currently road authorities rely on multiple different decision making-frameworks to help identify investment opportunities for the road network. The framework used often varies depending on the nature of the expenditure. For example, cost benefit…

This report proposes a holistic and risk based prioritisation framework to support investment decisions across road asset classes and expenditure categories. Transport agencies currently rely on different decision making frameworks to help identify…

This user guide provides guidance to road managers, planners and designers on achieving improved safety outcomes by applying consistent standards along a road corridor. Thirteen road stereotype tables were identified covering the road network from…

This report summarises activities undertaken to produce guidance on road cross-section design for road stereotypes during stage 1 and 2 of this project. The guidance enables road managers, planners and designers to achieve improved safety outcomes…

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 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).

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/…
