Flexible granular pavements protected by sprayed seal surfacings are the backbone of the Australian and New Zealand road networks. Road agencies in Australia and New Zealand have therefore been focused on producing quality, long-lasting sprayed seal…

This report presents the findings of site inspections and binder ageing performance studies associated with two Austroads sprayed seal trial sites constructed near Coober Pedy, South Australia and Cooma, New South Wales. These trials were…

This test method sets out the procedure for determining the rubber content of a crumb rubber modified binder using a Soxhlet extraction apparatus. This test method is applicable to crumb rubber modified binders used in constructing and maintaining…

The AS 5100 Standard provides requirements for multiple-performance-level barriers. Historical barriers constructed before 1970 generally do not meet modern requirements for safety. This paper builds on ongoing previous research projects within…

Consistency in the design of traffic barriers for bridges has been identified as a major issue in current practice throughout Australia and New Zealand. The need for standard solutions was recognised by road jurisdictions, consultants and…

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…

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.
