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…

Fibre reinforced seals comprise a sprayed sealing treatment consisting of a layer of glass fibre strands sandwiched between two coats of a polymer modified bituminous emulsion. The fibres are applied randomly to form a mat that resists reflective…

The 2004 Austroads Pavement Design Guide provides guidance on the design of new pavements for moderate-to-heavily trafficked roads. For lightly trafficked roads, Austroads have published a companion document ‘Pavement Design for Lightly Trafficked…
