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…

Road tunnels are an important element of the transport infrastructure, requiring significant resources and energy to construct, operate and maintain. Consequently, they are potentially a major source of greenhouse gas emissions and environmental…

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…

Road tunnels are major pieces of infrastructure across the road network, and the number of tunnels is expected to increase in the coming years. Although they are relatively safe, a significant number of crashes occur on the approaches to and within…

This report evaluates selected low-cost perceptual countermeasure (PCM) treatments in tunnel environments. PCM treatments are used to reduce crash risk by improving driver speed behaviour, alertness and lane discipline within tunnels. Two key…

A recently completed project has recommended changes to the Austroads Guide to Road Tunnels Part 2: Planning, Design and Commissioning to provide guidance on rationalising road signs on the approaches to tunnels, to divert over-height and dangerous…

This Test Method determines the susceptibility of aggregate to an expansive reaction when mixed with cement in a concrete mix. It measures the change in length of concrete prisms containing the aggregate under investigation. This Test Method is not…

This Test Method determines the susceptibility of aggregate to an expansive reaction when mixed with cement in a concrete mix. It measures the change in length of representative mortar bars containing the aggregate under investigation during storage…

Austroads Technical Specification ATS 5820 specifies the requirements for the supply and application of anti-graffiti coating systems to structures, roadside furniture and traffic controller boxes. It excludes the application of coating systems to…

This test method determines the performance of anti-graffiti coatings and is based on Main Roads Western Australia Testing Method for Anti-Graffiti Coatings 6706-02-2238. This Test Method assesses the following properties: ease of removing graffiti…
