This report examines the performance of different types of speed-reducing treatments (or combinations of treatments) in high-speed environments. The project also considered how desired speed can be aligned with a safe, anticipated operating speed…

This document is an update of the design procedure for double/double sprayed seal surfacing. The information supersedes that in Update of the Austroads Sprayed Seal Design Method(Austroads 2006), and replaces Sections 6, 7 and 8 in that document.

This 2013 presentation by the ARRB Group provides an introduction to the Austroads Design Vehicles and Turning Path Templates.

This review of research, newly published material and emerging practice has identified areas where additional advice and guidance on pedestrian facilities can be incorporated into the Austroads Guides. Greater recognition of the importance of…

Polished aggregate friction value (PAFV) tests are used by most jurisdictions in Australia to determine the resistance of aggregates to the polishing action of vehicle tyres on the road. Two versions of the PAFV test are used in Australia: the…

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…

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…

The work described in this report determines updated cutter level recommendations for S10E and S20E binders. Studies were also conducted to investigate the relationship between the contact angle of water on films of bitumen and PMB binders, and…

This Pavement Work Tip is a practical guide for restoring texture to bleeding or flushed surfaces by applying additional aggregate with the assistance of chemical solvents.

ARRB Group has completed a major Austroads research program to assess risk involving road, traffic and roadside infrastructure. The results provide road authorities with more effective tools to reduce road crashes and injuries. The objectives for…
