This test method describes the methods for the determination of the flexural modulus, strength and fatigue characteristics of laboratory‑manufactured cemented materials using four point bending techniques.

The report provides a summary of works undertaken during the period 2016–17 for the Austroads project AT1064 – Long-term pavement performance (LTPP).

Austroads has funded the long-term pavement performance study since late 1994. The project monitors…

This report presents the summary of project activities conducted in 2006/07. A number of suitable sealed granular pavement sites were identified across Australia for inclusion in the LTPP study. An improved revised method was used to calibrate HDM-4…

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…

The establishment of an asphalt field trial requires considerable planning and usually involves significant resources. The selection of a trial site can significantly affect the likelihood of a clear outcome. The information provided will assist in…

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…

A review of bleeding or flushed seals was undertaken to determine what physical changes had taken place within the seal that had resulted in the binder lying at or close to the surface. The evaluation process used a visual appraisal and a digital…
