National Survey of Bitumens: 2006 to 2012

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…

Fourth National Survey of Australian Bitumens

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…

Investigation into the Properties of Alternative Surfacing Binders and Bitumen Extending Binders

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…

Review of Innovative Binder Delivery Systems (Pilot Study)
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…
Australian and International Bituminous Binder Specifications
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…
Review of Foamed Bitumen Sealing in Australia
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…
The Results of Testing Overseas Bitumen
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…
Bitumen Emulsions
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…
