Performance modelling is an asset management tool used to quantify or qualify the performance of a bridge within the context of the overall bridge network. Performance modelling techniques include the use of performance indicators and deterioration…

This report summarises the findings from the first year of a three-year study which reviews the safety performance of road infrastructure elements identified as Safe System solutions. The first stage sought to identify these solutions and to…

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 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…

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…

Consideration is being given to the use of new methods of characterisation to improve performance prediction in the Austroads pavement design procedures, including flexural strength, breaking strain and flexural modulus.

This study evaluated cemented…

This report examines the selection of an appropriate laboratory compaction device for stone mastic asphalt (SMA). The laboratory compaction of the SMA mix is crucial as the volumetric properties are selected based on the results from laboratory…

This study investigated the potential introduction of the French high modulus hot mix asphalt technology, called enrobés à module élevé (EME) to Australia. The EME mix technology provides a high performing asphalt material for use in heavy duty…

This report documents a study designed to predict temperature and load frequency in asphalt pavements and their effect on the modulus of the asphalt material. It is the first report from a three-year Austroads project which aims to improve the…
