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 report includes the examination and recommendation of a five-layer framework to implement controller functions. The key benefit of this concept is the clear demarcation of functions. The proposed concept allows functions to be built logically…

Stabilisation may be defined as a process by which the intrinsic properties of a pavement material are altered by the addition of a stabilisation binder to meet performance expectations in its operating, geological and climatic environment. Part 4L…

Part 10: Subsurface Drainage provides advice on the general requirements for drainage materials, design of pavement drains and construction and maintenance considerations. This Part contains information on the types and uses of subsurface drainage…

Guide to Pavement Technology Part 7: Pavement Maintenance provides broad guidance on current routine maintenance practices for sealed pavements suitable for use by both supervisory and field staff. 

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…

Computer processing power and memory availability have significantly advanced in the last few decades. New concepts in controller architecture and new vehicle detection technologies are now also available. Project NS1377 (Traffic Signal Controllers…

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…
