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…
Austroads Project AT1064 Long Term Performance Monitoring and Model Development was initiated in 1994/95. The project was reviewed in 2003 and later in 2007 by GP Youdale Consulting Engineers to assess the project’s program and progress and, if…
The use of warm mix asphalt (WMA) appears to be increasing throughout the developed world in place of conventional hot mix asphalt (HMA). Acceptance depends upon confirmation of the environmental benefits and that on-road performance is at least…
