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…

This report examines the capacity of the extra-large wheel-tracking laboratory test method to predict the in-service performance of granular materials.

Rutting is a common distress mode of unbound granular bases under thin bituminous surfacings.

Five…

EME2 mixes are produced using a hard paving grade bitumen applied at a high binder content (approximately 6%). Compared to conventional asphalt bases with unmodified binders, EME2 asphalt is characterised by high stiffness, high durability, superior…

This report provides a summary of activities completed during 2015–16 for the Austroads long term pavement performance monitoring project.

Austroads has funded the long-term pavement performance study since late 1994. The project monitors the…

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…

The report covers a variety of topics related to improving the design procedures for asphalt pavements in Australia. Literature reviews of perpetual pavement design concepts and the relationship between flexural and compressive modulus were…

This report summarises the activities undertaken during the 2013–14 year for the long term pavement performance (LTPP) monitoring project.

Austroads project AT1064 Long-Term Performance Monitoring to Develop Consistent Performance Models has…

This report documents research to validate the wheel-tracking approach as a complementary means of evaluating the rutting performance of granular bases. Firstly, the influence of the moisture content on the laboratory wheel-tracking performances is…
