A new approach to laboratory testing of stabilised materials

This paper outlines how research is being used to deliver the best outcomes to designers and laboratory technicians and work towards a consistent approach to the testing of stabilized materials in Australia. The paper also includes a discussion on further research needs to further refine laboratory testing and resolves some of the uncertainty in results of the current test methods. Using the research and performance data now available along with similar test methods, a new series of test methods based on research outcomes is currently being developed. These will be specific for road construction and represent a significant step forward in the harmonization of Australian laboratory procedures. These test methods also give consideration to existing test moulds, mechanized elements of the test, all binder types and will be free to access from the Austroads web site.
