This report summarises the findings from the first year of a three-year study which reviews the safety performance of road infrastructure elements identified as Safe System solutions. The first stage sought to identify these solutions and to…

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 documents the outcomes of an Austroads project which considered the asset management implications of the new Safe System approach and investigated what implementing a Safe System would mean for asset managers. The report provides a…

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 document reports on the implementation phase of the Indigenous Safe System Demonstration Project in Bidyadanga, Western Australia. In this phase a funding strategy was developed for the implementation plan which was prepared in the second half…

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…
