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…

Investigation into the Properties of Alternative Surfacing Binders and Bitumen Extending Binders

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…

Segregation and Degradation in Commercial SBS Binders

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…

The Effect of Styrene Butadiene Styrene (SBS) Morphology on Field Performance and Test Results: An Initial Study

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…

Review of Innovative Binder Delivery Systems (Pilot Study)
This report presented a summary of three pilot studies completed on bitumen emulsions, foam bitumen sprayed sealing and warm mix asphalt.Increasing awareness of environmental issues and energy conservation have led to identifying alternative binder…
Australian and International Bituminous Binder Specifications
This literature review covers the development of bitumen specifications and test procedures from Australia, USA, Europe and South Africa. In order to have a better understanding of the imported bitumens into Australia, this report discusses the…
