A database of the properties of bitumens used in Australia has been collated over the course of this project (2006/12). This database will be useful in identifying possible trends in properties associated with changes in the manufacture of…

This report describes studies of the effects of test conditions on vertical polished aggregate friction value (PAFV) results and the results of a proficiency study which was conducted to determine a preliminary PAFV value for UK aggregate. The…

This report presents a proposed methodology to guide the development of new rest areas and upgrading of existing rest areas. It aims to assist road authorities identify needs for rest areas for heavy vehicles focussing on capacity and spacing…

This report provides input to the Austroads project Performance of Warm Mix Asphalt Pavements. It involves a literature review of existing CO2-e emission calculators applicable to road construction (using asphalt products) with a view to…

Cutting solvents have been traditionally added to binders used in sprayed sealing in Australia and New Zealand to ensure that effective adhesion occurs between binder and aggregate. Recent Polymer modified binder (PMB) sealing failures, which have…

This report discusses infrastructure and traffic management issues identified in an examination of approximately 700 crash investigations conducted in metropolitan and rural areas of South Australia. Current traffic management and engineering…

The Directors' Report 2012 provides an overview of the Austroads' Board and financial statements for the year ended 30 June 2012.

This report reviews the use of point-to-point speed enforcement internationally in order to provide principles for better practice for its use in Australia and New Zealand. Point-to-point enforcement is a relatively new technological approach to…

This report is the fourth in a series which examines the properties of bitumens used in Australia. The bitumen testing program was undertaken to develop a database of selected bitumen samples dating back to 1956. This database has been used to…

This report outlines the application of a methodology developed for assessing the impact of a potential length increase for PBS Level 1 vehicles, based on the assessment criteria identified and discussed in workshops conducted in 2011. Fifty-five…
