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…

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…

Estimating the Cost of Accelerated Road Wear due to Increased Axle Mass Limits - Stage one: Site Identification

This report details the work undertaken in the first year of the three year Austroads project Improving the Estimation of the Cost of Accelerated Road Wear due to Possible Increases in Axle Mass Limits. In 2011-12 the project identified road sites…

Austroads LTPP and LTPPM Study: Summary Report for 2006/07
This report presents the summary of project activities conducted in 2006/07. A number of suitable sealed granular pavement sites were identified across Australia for inclusion in the LTPP study. An improved revised method was used to calibrate HDM-4…
Impact of Rising Watertables and Salinity in Pavement Performance
Austroads sponsored a technical research project Managing the Impacts of Rising Watertables and Salinity on Pavement Performance . The overall desirable deliverables were tools to assist road authorities to identify those sections of road that are…
Assessment of Remaining Service Life of Pavements
This report documents the assessment of RSL of pavements where the RSL is confined in its estimation to the occurrence of the next major intervention either by rehabilitation or replacement. There are many measurable surface distress conditions,…
