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…

In Australia and New Zealand, bituminous binders used in road construction are tested prior to use to ensure they will perform satisfactorily during road construction/maintenance. Some of the Australian Standards that are used for these tests have…

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 test method describes the procedure for determining the cone penetration of a joint sealant at 25 

This test method describes the procedure for determining the resistance of hot poured joint sealants to flow at a temperature of 70 °

This test method sets out the procedure to be used to prepare joint sealant samples for testing.

This test method describes the procedure for determining the degree to which a joint sealant is degraded by heat during prolonged storage (6 

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…
