This report details the testing of 21 Austroads jurisdictions mixes and one airport mix to develop a relationship between the Austroads Gyropac Gyratory compactor, which is now redundant, and the Servopac (setup to AS/NZS) and Superpave Gyratory…

This report documents the delivery of the first component of a new Austroads performance-related asphalt specification framework. This included the development of several new test methods and updating a number of existing test methods for use in…

This report documents the findings of the first stage of an Austroads project which aims to benchmark the laboratory fatigue performance of locally manufactured asphalt mixes against the performance predicted by the Shell relationship in Austroads…

This report describes research into the development of a draft Austroads evaluation protocol for rejuvenators. Rejuvenators are typically used to produce asphalt mixes containing high levels of reclaimed asphalt pavement (RAP). The report includes a…

The purpose of this literature review is to assess the current body of research for the incorporation of recycled material in pavements to inform updated guidance to the current Austroads Guide to Pavement Technology Part 4E: Recycled Materials. New…

Crumb rubber binders have been used to construct sprayed seals in Australia for many decades but have not been utilised in asphalt in the past. Due to the lack of crumb rubber binder grades in the Australian national polymer modified binder (PMB)…

This report documents the technical basis of the 2010, 2012 and 2017 editions of Austroads&rsquo

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…

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…

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/…
