This Pavement Work Tip refers to minimising the risk of bleeding when carrying out sprayed sealing work during extreme hot weather events, especially when subject to slow moving or stationary heavy traffic, or unusually heavy loads.

The asphalt industry is rapidly evolving, and it is widely accepted that prescriptive specifications are not necessarily well suited to take full advantage of the benefits that new and innovative technologies can provide. There is therefore a desire…

This document describes the procedures to be followed to test an asphalt specimen using a wheel tracking test device. The procedures can be carried out on prismatic specimens that have been manufactured in the laboratory, cut from an existing…

This document describes the procedures to verify that a wheel tracking test device complies with the requirements of those devices permitted for use in Austroads test method ATM 231. The procedures are advisory rather than mandatory and reference…

The test method specifies procedures for the characterisation of the stiffness and fatigue behaviour of bituminous mixtures using a four point bending test configuration. The test procedure to characterise the complex modulus is contained in Section…

This report documents the delivery of the first component of a new Austroads performance-related asphalt specification framework. This included the development of several new test methods and updating a number of existing test methods for use in…

The Austroads mechanistic-empirical design system documented in Part 2 of the Guide to Pavement Technology uses a laboratory fatigue relationship previously developed by Shell to predict the fatigue life of asphalt layers. The Shell fatigue…

This report documents the findings of the first stage of an Austroads project which aims to benchmark the laboratory fatigue performance of locally manufactured asphalt mixes against the performance predicted by the Shell relationship in Austroads…

The use of reclaimed asphalt pavement (RAP) in new asphalt mixes is a common practice in Australia and New Zealand due to its many benefits. RAP contents are typically about 10&ndash

This report describes research into the development of a draft Austroads evaluation protocol for rejuvenators. Rejuvenators are typically used to produce asphalt mixes containing high levels of reclaimed asphalt pavement (RAP). The report includes a…
