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…
This report details the first year of a three-year Austroads project to transfer French Enrobés à Module Élevé Class 2 (EME2) technology to Australia. EME2 technology offers the prospect of reduced asphalt thicknesses for heavy duty pavements, and…
There is a need to improve the Austroads procedures for the mix and structural designs of foamed bitumen stabilised materials.
This progress report summarises the mix design test methods drafted to date and those planned for 2014-15 within the…
This report describes inspections conducted on double/double primerseals constructed in Victoria.
It is not typical practice to use two-layer primerseals, or polymer modification in primerseals, and methods to do so are not described by Austroads…
This report details the findings from visual inspections conducted on two Austroads sprayed seal field trials: a non-modified binders trial near Gisborne,
