Polymer modified binders (PMBs) are increasingly used in road construction as they provide enhanced performance properties compared with conventional bitumen. Even though PMBs show enhanced service properties, they may show degradation or changes in…

This report presents the results of a laboratory study that was conducted as part of the development of a new-long term ageing (durability) test for bituminous binders used in sprayed seals in Australia.

Among the number of test methods reviewed and…

Austroads project AT1539 developed guidance for the use of new technologies that can improve the efficiency of road asset managers. This report is the second stage of the project and it assesses eleven new technologies that can be potentially useful…

This report outlines the process for asset management plans (AMPs) and long-term financial plans (LTFPs) in Australia, as well as the compilation and use of financial sustainability indicators in this regard.

This Pavement Work Tip provides a handy summary of the Austroads AP-T235-13 Guide to the Selection and use of Polymer Modified Binders and Multigrade Bitumens.

This study examines the value and need for network-level pavement deflection data to support road asset management decisions. The outcomes of the study provide critical input to decisions to undertake network-level strength assessment across…

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…

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…

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…
