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/…

Austroads Project AT1064 Long Term Performance Monitoring and Model Development was initiated in 1994/95. The project was reviewed in 2003 and later in 2007 by GP Youdale Consulting Engineers to assess the project’s program and progress and, if…

This Pavement Work Tips provides guidance on estimating the amount of time available to achieve effective compaction under various conditions.

A major study was undertaken to determine relationships between binder rheological properties and the rut resistance of asphalt mixes, as indicated by the laboratory wheel tracking test. Twelve binders, including three bitumens, a Multigrade binder…

Over the last decade a considerable amount of research effort has been focussed on the development of a repeated load triaxial (RLT) test procedure to assist practitioners in the use of natural and marginal unbound base/subbase materials in road…
