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 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 investigates the origins of the current Unconfined Compressive Strength (UCS) criteria that differentiates modified granular materials from bound materials. Based on the review, a number of changes to the UCS design criteria are…
To assess permanent deformation of granular materials repeated triaxial tests are currently used. A previous research project highlighted interest in using a wheel-tracking test to obtain a better agreement with field performance.
A new wheel-tracker…
To assess permanent deformation of granular materials, repeated triaxial tests are currently used in Australia. A previous research project highlighted interest in using a wheel-tracking test to obtain a better agreement with field performance. A…
This report details the data collected during the performance assessment of a typical unbound granular pavement under accelerated loading, using the Accelerated Loading Facility (ALF) with single, tandem and triaxle axle group loads.
As part of 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…
