Establishing a Reference Aggregate for Aggregate Polishing Tests

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…

A New Reference Aggregate for PAFV Testing

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…

Aggregate Wetting and Initial Adhesion of Sprayed Sealing Binders

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…

Aggregate Wetting Experiments and Effects on Recommended Polymer Modified Binder Cutter Levels

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…

Managing Asset Management Related Civil Liability Risk
Claims for compensation brought by road users against road authorities remain a significant issue across Australia. Further, the claims environment varies between jurisdictions (states and territories) and differences have been found in the…
