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…
This report presents a review of the available structural design methods for foamed bitumen pavements, as a first step in the development of thickness design procedures. Six design procedures were found in the literature, most of them based on well…
This report presents the test results of bitumens used across different states in Australia. This database will be useful in identifying possible trends in properties associated with recent changes in the manufacture of Australian bitumens and…
This report is the second in a series which examines the properties of Australian bitumens from around Australia. Thirty-one bitumens from around Australia were subjected to a range of test procedures. These included viscosity measurement at a range…
A significant factor contributing to the establishment of Australia’s large network of surfaced roads has been the successful application of sprayed sealing technology, including the selection of treatments, design of the treatments and application…
Austroads Project No: TT1358: Review of Structural Design Procedures for Foamed Bitumen Pavements proposed a method for the thickness design of foamed bitumen to be adopted in principle by Austroads. Foamed bitumen is a mixture of hot bitumen, water…
