Overseas research has suggested that asphalt fatigue endurance limit may exist, where applied strain is sufficiently low no fatigue damage accumulates in the asphalt as the rate of asphalt healing exceeds the rate of damage accumulation. The…

This document is an update of the design of initial treatments for sprayed seal surfacing.

The information contained within this document supersedes that found in Austroads AP-T68-06 Update of the Austroads Sprayed Seal Design Method, and replaces…

The principal aim of this work was to examine the effect of heavy vehicle loading on sprayed seals, in order to incorporate such loading impacts into the Austroads sprayed seal design method.

The current sprayed seal design method uses an equivalent…

This report describes a literature review on the bitumen/binder specifications and test methods used in Australasia, USA, Europe and South Africa. The project investigated whether the Australian and New Zealand bitumen specifications are adequately…

The use of recycled asphalt pavement (RAP) in asphalt mixes provides a vital basis for sustainable development. Maximising the re-use of RAP in its highest value application, as new asphalt product, has significant economic and environmental…

This report is the final deliverable of a three year Austroads project to improve the design procedures for asphalt pavements. The object of the work in this final year was to validate the proposed improved procedures for the characterisation of…

This report summarises work conducted to establish a compaction procedure for the Austroads asphalt mix design process. Part of the early work examined overseas research and this is briefly summarised to provide supporting evidence as to the…

The Austroads asphalt mix design method was developed in 1997 and has had a number of revisions over the intervening years as test methods evolve and experience is gained. However, implementation of the method has been variable across the various…

The development of an Austroads asphalt mix design procedure led to adaptation and adoption of a number of overseas test methods. These test methods were then compiled into what has become a suite of Austroads test methods. The Austroads test…

This report presents a review of the available structural design methods for foamed bitumen pavements, as a first step in the development of thickness design procedures. Six design procedures were found in the literature, most of them based on well…
