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,
A mobile pavement surface wear rig has been constructed, which aims to gain an improved understanding of the failure mechanisms that are particular to the pavement surfacing layer – as distinct from the structural layers – that may be caused by…
This report provides asset managers with practical guidance in the development and delivery of effective resealing programs. It builds on accumulated experience of previous studies and a review of sprayed seal performance throughout Australasia.
