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 has been prepared by the Austroads Emulsion Project to provide general information on the use and application of bitumen emulsions in Australia and New Zealand. The information contained herein has been compiled from surveys and project…

The report describes the work undertaken in the first year of a two-year project to assist implementation of a new Australian asphalt mix design procedure. The main tasks undertaken were (i) preparation of an update for the Australian Provisional…

This framework for specifying asphalt has been prepared by Austroads and the Australian Asphalt Pavement Association, with input from the New Zealand Pavement and Bitumen Contractors Association (BCA) to promote national uniformity and good practice…

This report provides mix design flow charts for stabilised materials using lime, cementitious and bituminous binders. The mix design is based on laboratory characterisation using state-of-the-art approaches used by State Road Authorities, local…
