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 report is the first progress report of a four year project which aims to improve the Austroads procedures for the mix and structural design of foamed bitumen stabilised materials.
The report summarises the test methods drafted to date and…
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.

The 2011 Austroads Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design includes an interim procedure for the thickness design of foamed bitumen stabilised (FBS) pavements. This project aimed to validate the interim…
This report presents the results of a laboratory study to investigate development of a new durability test method that is acceptable for use in Australia. The study aimed to develop a more robust long-term ageing test method and resolve the issues…
