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…
The temperature sensitivity (K factor) of the ball penetration test is an important parameter in estimating the embedment allowance of the overlaying seal design. A series of ball penetration tests were performed in the laboratory to investigate the…
This report reviewed various approaches to produce warm mix asphalt (WMA) and their laboratory and field assessments. Reviewed technologies are the foamed mix based products (Aspha-Min, WAM-Foam and LEA), organic additive products (Sasobit,…
