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…

This report documents the surface life prediction models that have evolved from the long term sampling of the bitumen in sprayed seals and thin asphalt surfaces. The estimation of surface life is predicated on the basis of the mechanism of bitumen…

Little data is available to allow trends in bitumen properties to be determined or to compare the properties of bitumens used in different jurisdictions. Such information will become important as more imported, non-traditional bitumens are used in…

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…
