Effectiveness of Road Safety Engineering Treatments
Previous Austroads research has identified that there is a lack of reliable information regarding the effectiveness of different road safety engineering treatments.
An Introductory Guide for Evaluating Effectiveness of Road Safety Treatments
This report outlines the methods that can be used in the evaluation of road safety treatments, and discusses the data requirements, and the advantages and disadvantages of each approach. It is designed to assist selection of the most appropriate…
Improving Roadside Safety - Stage 3: Interim Report
The objective of this project is to improve the safety performance of roadsides. The Stage 3 interim report of this project presents the project findings achieved during the 2010-11 financial year. Stage 3 builds on findings and recommendations of…
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…
