This report details a review undertaken to identify potential issues that are limiting the uptake of the PBS (Performance Based Standards) Level 3 and 4 vehicles and provide recommendations for improving the standards to increase the use of safer…

This report documents the process and results of industry consultation in relation to a nationally harmonised pilot and escort vehicle driver accreditation scheme and operational guideline proposed in 2013.

This report documents research to validate the wheel-tracking approach as a complementary means of evaluating the rutting performance of granular bases. Firstly, the influence of the moisture content on the laboratory wheel-tracking performances is…

These guidelines have been developed to help councils plan and assess road freight access to industrial areas, including ensuring that infrastructure provided by developers is adequate to meet access needs for many years.

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…

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 presents the current situation for pilot and escort vehicle drivers in Australian jurisdictions, and proposes a nationally harmonised approach. This approach was developed in consultation with jurisdictional stakeholders through…

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…
