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…

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 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…

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 presented a summary of three pilot studies completed on bitumen emulsions, foam bitumen sprayed sealing and warm mix asphalt.Increasing awareness of environmental issues and energy conservation have led to identifying alternative binder…

This literature review covers the development of bitumen specifications and test procedures from Australia, USA, Europe and South Africa. In order to have a better understanding of the imported bitumens into Australia, this report discusses the…

In 1993, Austroads performed an extensive trial of foamed bitumen sprayed sealing in Australia, as a part of environmental and energy effective sealing technology development program. The trials were conducted in various states and reported to be…

Overseas bitumens are now being imported into Australia and the properties of possible future imports were evaluated. Overseas bitumens from various sources were obtained and subjected to a range of chemical and physical tests. These included…

This report reviewed overseas and Australian experience in using bitumen emulsions. Increasing economic and environmental pressures have induced an increase in demand for the use of bitumen emulsions overseas. However, emulsion sprayed seals are…
