Framework for the Revision of Austroads Design Procedures for Pavements Containing Cemented Materials

The laboratory characterisation of cemented materials for road pavements was completed in Austroads Project TT1359 Cost-Effective Structural Treatments for Rural Highwaysand more recently in Austroads Project TT1664 Cemented Materials…

Characterisation and Performance Evaluation of Granular Bases Project: Pavement Construction Report

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…

Towards Incorporating Heavy Vehicles into the Austroads Sprayed Seal Design Method

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…

Analytical Study of Performance Models for Unbound Granular Pavements

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…

Development of a Stone Mastic Asphalt Mix Design Procedure: Selection of Appropriate Compaction Equipment for the Mix Design

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…

EME Technology Transfer to Australia: An Explorative Study

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…

Improved Design Procedures for Asphalt Pavements: Pavement Temperature and Load Frequency Estimation

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…

Design and Performance of Foamed Bitumen Stabilised Pavements: Progress Report 1

This report is the first progress report of a four year project which aims to improve the Austroads procedures for the mix and structural design of foamed bitumen stabilised materials.

The report summarises the test methods drafted to date and…

Maximising the Re-use of Reclaimed Asphalt Pavement: Binder Blend Characterisation

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…

Polymer Modified Binder Sprayed Seals Trials: Construction Report

This report describes the planning and construction of Australian field trials which will measure of the relative performance of polymer modified binders (PMBs) used in strain alleviating membranes in sprayed bituminous sealing. Issues addressed in…
