This report documents the best practice approaches for the use of road tunnel wall panels and finishes, which informed the development of a specification framework. This was developed through a workshop with subject-matter experts, review of current…

This report outlines a detailed and contemporary review of in-tunnel aesthetic features applied and tested, and how such features can be considered throughout the project lifecycle: planning, design, procurement, operation, maintenance, testing and…

This report, originally published in November 2021, outlines the findings of a project to develop clearer and more consistent tunnel signage to reduce the impact of over-dimensioned and dangerous goods vehicles on both infrastructure and Workplace…

This report documents a project undertaken to investigate the issues associated with managing the planning, construction, operation and maintenance of road tunnels in a sustainable manner. The results of the investigation informed an update to all…

This report sets out the process though which fire incident and fire safety operational information was collected for eleven major road tunnels in Australia. This tunnel data set are the major tunnels in Australia as defined by physical…

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 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…

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…

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…
