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…

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 report examines the viability of using recycled plastics in asphalt and sprayed seals by Australian and New Zealand road authorities. The report presents the findings of a literature review, including case studies of local and overseas road…

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…

This document sets out the performance requirements expected of bitumen sprayers operating in Australia and New Zealand.

For a consistent and high quality of sprayed sealing work to be undertaken, and for sprayed sealing to remain a viable surfacing…

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).

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/…
