This report describes the proposed Strategy for implementation of Assessing Fitness to Drive for consideration by the Austroads Board. It has been developed based on the Implementation Framework endorsed by the Austroads Board in 2021, together with…

Driving a motor vehicle is a complex task involving perception, appropriate judgement, adequate response time and appropriate physical capability. A range of medical conditions, disabilities and treatments may influence these driving prerequisites.…

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…

The characterisation of the flexural stiffness and fatigue behaviour of bituminous mixtures in Australia and New Zealand is undertaken using a four-point bending (4PB) configuration. This document describes the procedures to be followed to verify…

This test method sets out procedures for the preparation of asphalt specimens and measuring the change in indirect tensile strength resulting from the effects of moisture and freeze/thaw conditioning. The results can be used to assess the propensity…

The test method outlines the procedure for determining the permeability of a water-saturated asphalt specimen in the laboratory using the ponding method. The test method was primarily developed for dense-graded, stone mastic and gap-graded asphalt…

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 document describes the procedures to be followed for compacting asphalt specimens using a gyratory compactor.
