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/…

This report presents the summary of project activities conducted in 2006/07. A number of suitable sealed granular pavement sites were identified across Australia for inclusion in the LTPP study. An improved revised method was used to calibrate HDM-4…

This report presented a summary of three pilot studies completed on bitumen emulsions, foam bitumen sprayed sealing and warm mix asphalt.Increasing awareness of environmental issues and energy conservation have led to identifying alternative binder…

This literature review covers the development of bitumen specifications and test procedures from Australia, USA, Europe and South Africa. In order to have a better understanding of the imported bitumens into Australia, this report discusses the…

The establishment of an asphalt field trial requires considerable planning and usually involves significant resources. The selection of a trial site can significantly affect the likelihood of a clear outcome. The information provided will assist in…
