Previous Austroads research has identified that there is a lack of reliable information regarding the effectiveness of different road safety engineering 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…

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…

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…

Bitumen is a major component used in the construction of roads in Australia and New Zealand. As it can only be manufactured from a small number of the crude oils in the world, the future supply and cost of bitumen will be directly linked to the…

This study obtained an indication of the proportion of Australian commercially manufactured polymer modified binders (PMBs) liable to segregate, identifed suitable tests to measure segregation propensity and proposes measures to help prevent or…

Styrene butadiene styrene (SBS) is the most commonly used polymer modified binder (PMB) type. It provides substantial performance enhancement in seals and asphalts, compared to unmodified bitumen. However, there have been field failures, and…
