Flexible granular pavements protected by sprayed seal surfacings are the backbone of the Australian and New Zealand road networks. Road agencies in Australia and New Zealand have therefore been focused on producing quality, long-lasting sprayed seal…

This report presents the findings of site inspections and binder ageing performance studies associated with two Austroads sprayed seal trial sites constructed near Coober Pedy, South Australia and Cooma, New South Wales. These trials were…

This webinar, presented by Robert Urquhart on 11 August 2020, gives an overview of an Austroads project which provided expert technical input into the update of four Australian standards which were revised by the Standards Australia Technical…

Austroads Technical Specification ATS 3480 sets out the requirements for the following treatments to the surface of bituminous pavements: improving the surface texture of sprayed seals by removing excess binder (&lsquo

This webinar, presented on 17 February 2020, provides an overview of the life cycle management of local sealed and unsealed  roads. It highlights the Austroads Guides and the AUS-SPEC national local government specification system which assist local…

This report presents a review of the available structural design methods for foamed bitumen pavements, as a first step in the development of thickness design procedures. Six design procedures were found in the literature, most of them based on well…

This report presents the test results of bitumens used across different states in Australia. This database will be useful in identifying possible trends in properties associated with recent changes in the manufacture of Australian bitumens and…

This report is the second in a series which examines the properties of Australian bitumens from around Australia. Thirty-one bitumens from around Australia were subjected to a range of test procedures. These included viscosity measurement at a range…

A significant factor contributing to the establishment of Australia’s large network of surfaced roads has been the successful application of sprayed sealing technology, including the selection of treatments, design of the treatments and application…

Austroads Project No: TT1358: Review of Structural Design Procedures for Foamed Bitumen Pavements proposed a method for the thickness design of foamed bitumen to be adopted in principle by Austroads. Foamed bitumen is a mixture of hot bitumen, water…
