Options to Extend Coverage of Alcohol Interlock Programs
Despite high levels of community education and sustained enforcement, alcohol-related crashes and drink-driving offences continue to pose a threat to road safety.
Development of a Binder Test to Rank the Low Temperature Cracking Resistance of Polymer Modified Binders

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…

Development of a Durability Test Method for Sprayed Sealing Binders: A Field Validation Study

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…

Improved Design Procedures for Asphalt Pavements: Outcomes for Year 2 of 3

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…

Options for Rehabilitation in Interlock Programs
This report examines the effectiveness of national and international programs that treat and rehabilitate drivers with alcohol dependence and the criteria used to approve the removal of interlocks.
Austroads LTPP/LTPPM Study - Summary Report 2013-14

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…

Effect of Moisture Content and Laboratory Preparation Conditions on the Permanent Deformation of Unbound Granular Materials

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…

Polymer Modified Binder Sprayed Seal Trials
Two significant road trials have been initiated to better understand the performance defining properties of Polymer Modified Binders when used in sprayed sealing applications over cracked pavements. Treatments varied from manually applied crack…
Drugs and Driving in Australia
The effects of alcohol on drivers in reducing abilities and increasing the risk of being involved in road crashes is well known. In principle, any substance affecting the central nervous system can affect the abilities required to safely control a…
Drink Driving and Enforcement: Theoretical Issues and an Investigation of the Effects of Three Enforcement Programs in Two Rural Communities in Australia
This study addressed aspects of the ongoing drink-driving problem in rural areas of Australia, and further developed a recent theoretical account of the decision-making processes that might underlie the effect of enforcement on behaviour. The study…
