Probabilistic Road Deterioration Model Development

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…

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…

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…

State-of-the-Art Traffic Speed Deflectometer Practice

This report provides a brief state-of-the-art review of current traffic speed deflectometer (TSD) practice based on information gained from attending the deflection at road traffic speed workshop held in the UK in June 2012.

The current state of…

Future Availability and Assessment of Alternative Surfacing Binders

Bitumen, an important component used in road construction in Australia and New Zealand, is manufactured from a finite, non-renewable crude oil resource. A number of commercially available alternative binders and bitumen extended binders have been…

Review of Variability in Skid Resistance Measurement and Data Management
This report presents research outcomes of Austroads project AT1488: Improving skid resistance measurement, carried out from July 2009 to June 2012. The main goal of the project was to improve the understanding of variability associated with skid…
Development of Safety Related Investigatory Level Guidelines: A Worked Example of Methodology

This report provides a worked example for developing skid resistance investigatory level guidelines.

The worked example is sourced from Main Roads Western Australia (MRWA) and relates to texture measurement as a surrogate for skid resistance. A…

Austroads LTPP and LTPPM Study: Summary Report 2011-12

This report presents the summary of project activities conducted during the 2011/12 season, including a summary of the LTPP/LTPPM pavement condition survey results, a brief summary of the development of probabilistic road deterioration (RD) models…
