This report details the findings from visual inspections conducted on two Austroads sprayed seal field trials: a non-modified binders trial near Gisborne,
A mobile pavement surface wear rig has been constructed, which aims to gain an improved understanding of the failure mechanisms that are particular to the pavement surfacing layer – as distinct from the structural layers – that may be caused by…
This report provides asset managers with practical guidance in the development and delivery of effective resealing programs. It builds on accumulated experience of previous studies and a review of sprayed seal performance throughout Australasia.

Austroads established its long-term pavement performance (LTPP) project in 1995. Over the last few years, a significant number of sites have been removed from the study due to pavement rehabilitation and road improvement programs.

Polymer modified binders (PMBs) are increasingly used in road construction as they provide enhanced performance properties compared with conventional bitumen. Even though PMBs show enhanced service properties, they may show degradation or changes in…
This report presents the results of a laboratory 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.
Among the number of test methods reviewed and…
Australian and New Zealand road agencies, as well as transport agencies in the United States have indicated that there is a strong desire for standardised accuracy reporting methods, data interoperability and management, control or check…
Austroads project AT1539 developed guidance for the use of new technologies that can improve the efficiency of road asset managers. This report is the second stage of the project and it assesses eleven new technologies that can be potentially useful…
A new rut resistance approach based on the wheel-tracking test for unbound granular materials has been developed. The objective of the Austroads project TT1819 is to validate the wheel-tracker laboratory approach against large-scale Accelerated…
This report summarises the activities undertaken during the 2012–13 year for a long term Austroads pavement monitoring project.
Austroads project AT1064 Long-Term Performance Monitoring to Develop Consistent Performance Models was originally…
