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…
A database of the properties of bitumens used in Australia has been collated over the course of this project (2006/12). This database will be useful in identifying possible trends in properties associated with changes in the manufacture of…
This report is the fourth in a series which examines the properties of bitumens used in Australia. The bitumen testing program was undertaken to develop a database of selected bitumen samples dating back to 1956. This database has been used to…
Bitumen is a major component used in the construction of roads in Australia and New Zealand. As it can only be manufactured from a small number of the crude oils in the world, the future supply and cost of bitumen will be directly linked to the…
