There is a need to improve the Austroads procedures for mix design and structural design of foamed bitumen stabilised materials. This progress report summarises the mix design test methods drafted to date and those planned for 2015–16 within the…
The current version of the Austroads sprayed seal design method was published in 2006 and has been in use for the last nine years. During recent times, a number of sprayed sealing practitioners have indicated that the basic voids factor for single/…
The report covers a variety of topics related to improving the design procedures for asphalt pavements in Australia. Literature reviews of perpetual pavement design concepts and the relationship between flexural and compressive modulus were…
Traffic loadings on Australia’s extensive sprayed seal network have increased, particularly with freight efficiency resulting in longer and heavier loads being transported by prime movers.
This report details the development of a model to describe…
This report presents the findings from the second year of a three-year Austroads study which aims to maximise the re-use of reclaimed asphalt pavement (RAP) in new asphalt mixes.
A survey was conducted in Australia to identify the important issues…
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,
