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.…
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…
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…
The Austroads Guide to the Structural Design of Road Pavements: Pavement Design (now the Guide to Pavement Technology: Part 2 – Pavement Structural Design) has been used throughout Australia for over 20 years. Progressive development of the Guide is…
