This project aimed to consider options for the selection of an appropriate instrumentation package to fulfil future research needs and the development of a research program for future years. This involved email and phone consultation with a number…
The Austroads asphalt pavement design process set out in Guide to Pavement Technology – Part 2: Pavement Structural Design (Austroads 2008) utilises a mechanistic procedure to predict the allowable traffic repetitions until asphalt fatigue occurs.…
Local road expenditure data is collected and reported by the Australia Bureau of Statistics and used by the National Transport Commission (NTC) in its heavy vehicle charging methodology. This project is to improve local road expenditure data to…
A study of published information regarding the design and development of stone mastic asphalt (SMA) was undertaken. The main focus was upon obtaining information that had resulted in successful SMA mixes. In most instances the design of SMA had used…
This test was conducted to determine the relationship between wheel tracking characteristics found in a laboratory and rutting in real-world scenarios. A road trial was established in Brisbane at the Mount Coot-tha quarry. The site was chosen as it…
This document provides a guide to preparing samples for asphalt mix design to conform to Austroads design processes. It covers splitting of the raw components as well as compacting cylindrical and prismatic samples. The loose asphalt conditioning…
Road safety in rural and remote areas of Australia and New Zealand continues to be a major area of concern. Analysis of crash data also shows that a substantial proportion of crashes in these areas involve heavy vehicles. On average there have been…
This report reviews current developments in infrastructure-based safety-related ITS, documents their status in Australia and New Zealand, and makes recommendations for future developments in this area. A literature review is presented in which…
The benefits of using modern wire rope fences along roadsides as a safety barrier are well documented. Increasingly, this form of safety barrier treatment is being used in wide medians along divided carriageways for new freeways and motorways across…
Speed-related crashes are a continuing concern in Australasia. On behalf of Austroads, ARRB Group undertook to develop a framework for an intervention to promote safe driving among recidivist speeders.
Five key tasks were carried out: a literature…
