This report presents an analytical and parametric study to assess the relevance of rutting performance models for unbound granular pavements.
The rutting performance relationship used in the Austroads Guide to Pavement Technology Part 2 – Pavement…
This report details of the performance of polymer modified binder (PMB) trial sites in South Australia and New South Wales after 12 months service life. It includes related information such as the seal designs, binder testing in the laboratory, site…
This study investigated whether the segregation propensity of a polymer modified binder (PMB) during hot storage affects its performance on the road.
The Australian PMB specification currently includes a segregation test which determines whether the…
This report examines the selection of an appropriate laboratory compaction device for stone mastic asphalt (SMA). The laboratory compaction of the SMA mix is crucial as the volumetric properties are selected based on the results from laboratory…
This report documents a study designed to predict temperature and load frequency in asphalt pavements and their effect on the modulus of the asphalt material. It is the first report from a three-year Austroads project which aims to improve the…
This report presents the results of a literature review and laboratory study which was conducted as part of the development of a new-long term ageing (durability) test for bituminous binders used in sprayed seals in Australia.
The literature review…
Bitumen, an important component used in road construction in Australia and New Zealand, is manufactured from a finite, non-renewable crude oil resource. A number of commercially available alternative binders and bitumen extended binders have been…
This report describes the planning and construction of Australian field trials which will measure of the relative performance of polymer modified binders (PMBs) used in strain alleviating membranes in sprayed bituminous sealing. Issues addressed in…
This document provides a guide to the selection of modified binders including multigrade bitumens for different treatments and service conditions, and to assist in the use and interpretation of the Austroads Specification Framework for Polymer…
This document is an update of the design procedure for double/double sprayed seal surfacing. The information supersedes that in Update of the Austroads Sprayed Seal Design Method(Austroads 2006), and replaces Sections 6, 7 and 8 in that document.
