The Australian polymer modified binder (PMB) specification (AGPT/T190) currently requires different binder grades to be used in sprayed sealing and asphalt applications. This study compared the performance of PMBs representing four AGPT/T190 grades…

This webinar, presented on 17 July 2018, outlines ways to optimise the use of marginal and non-standard materials and gain best value from the successful performance of standard materials. It covers: applying a proposed assessment process to a wider…

There is a need to improve the Austroads procedures for mix design and structural design of foamed bitumen stabilised (FBS) materials. This final report summarises the mix design test methods developed within the context of an Austroads mix design…

This report considers the use of marginal and non-standard materials in road construction and maintenance. It concludes that considerable evidence exists, both nationally and internationally, that supports the wider use of marginal and non-standard…

This report details investigations that were conducted to verify the new Austroads sprayed seal design guidelines.

To verify the appropriateness of the proposed basic voids factor (Vf), and the initial sealing design approach (and also to validate…

This report describes research into development of a laboratory sprayed seal binder cracking test which can be used to measure the relative fatigue cracking resistance of thin binder films which have thicknesses comparable to the thicknesses of the…

Guide to Pavement Technology Part 4F: Bituminous Bindersprovides guidance on the use of bituminous materials in road construction and maintenance. Bituminous materials include bitumen obtained from refining crude petroleum oil and products derived…

This report describes the results obtained during the second year of work (2015–16) into the development of a binder test that can rank the low temperature cracking performance of PMBs.

Studies conducted during the first year of work (2014–15)…

The current Australian polymer modified binder (PMB) specification includes low temperature stiffness tests but does not include a binder test which ranks the resistance of PMBs to low temperature cracking on the road. This study investigated…

This report presents the results of a field validation 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.

The field validation study of the new…
