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…

This report documents an asphalt deformation trial established over a 1200 m length of Dandenong Road in Melbourne. The trial aimed to validate the wheel tracking used in the Austroads mix design method. The trial involved the placement of seven…

There has been renewed interest in emulsion seals in Australia, but an impediment to their widespread adoption has been perceived as adhesion problems. This study looks at adhesion test procedures and means of improving emulsion seal performance.…

There has been a continual increase in the number of large heavy vehicles nationwide since the review of the Austroads sprayed seal design method in 2001. This report aims to refine the traffic adjustment factor by updating and reanalysing the…

This report documents the process of assembling and reviewing the RMS NSW cracking data and the analysis of this data and its associated variables of climate, traffic load and pavement strength which has led to the development of a potential road…

The work documented in this report demonstrates the use of existing Austroads deterministic road deterioration (RD) models in a probabilistic approach to estimate the possible predictions for the dependent variables of these models. This approach…

This report presents an analytical and parametric study to assess the relevance of rutting performance models for unbound granular pavements.

The rutting performance relationship used in the Austroads Guide to Pavement Technology Part 2 – Pavement…

This study investigated whether the segregation propensity of a polymer modified binder (PMB) during hot storage affects its performance on the road.

The Australian PMB specification currently includes a segregation test which determines whether the…

This report details of the performance of polymer modified binder (PMB) trial sites in South Australia and New South Wales after 12 months service life. It includes related information such as the seal designs, binder testing in the laboratory, site…
