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…

Stabilisation may be defined as a process by which the intrinsic properties of a pavement material are altered by the addition of a stabilisation binder to meet performance expectations in its operating, geological and climatic environment. Part 4L…

A road trial was established at Gisborne on the Calder Highway. The aim of the trial was to review the performance of sprayed seals constructed from a number of binder types. Class 170 is typically used in Victoria for sprayed seals and a section…
