Guide to Traffic Management Part 13: Safe System Approach to Transport Management is concerned with traffic management practice under the Safe System philosophy. The Guide emphasises the need for the road system to provide an environment which…

This webinar, presented on 16 November 2017, provides an overview of the key changes to the Guide to Traffic Management Part 13, such as updated information on driver workload and the Safe System, and incorporation of a discussion on human factors.…

This report examines the capacity of the extra-large wheel-tracking laboratory test method to predict the in-service performance of granular materials.

Rutting is a common distress mode of unbound granular bases under thin bituminous surfacings.

Five…

This report details contemporary practices to mitigate risk and improve safety at road worksites.

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…

This report documents research to determine if the size of electronic regulatory speed signs (ERSS), such as variable speed limit signs, could be reduced without adversely impacting efficiency of driving or safety.

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 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…
