Part 4B of the Austroads Guide to Pavement Technology provides a recommended approach to the design and characterisation of asphalt mixes in Australia and New Zealand. However, the approach to asphalt mix design and performance characterisation…
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…
This report presents the findings from the first year of a three year Austroads study which aims to maximise the re-use of reclaimed asphalt pavement (RAP) in new asphalt product. The objective of this first year of study is to improve the…
This report presents details of a Warm Mix Asphalt (WMA) Evaluation Protocol. The Protocol guides the evaluation of specific WMA technologies and processes such as additives, surfactants and foamed bitumen, and sets out the conduct of appropriate…
This report presents the results of the laboratory testing program conducted in support of the validation trial of warm mix asphalt (WMA) and hotmix asphalt (HMA) conducted in Melbourne, Australia, between 2010 and 2012. Although the intention was…
This is the third annual report on the activities of Austroads member authorities in implementing the Austroads mix design procedure. Each road agency provided information for the report summarising their position with regard to the move to adopting…
