Austroads LTPP and LTPPM Study: Summary Report for 2006/07
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…
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…
Impact of Rising Watertables and Salinity in Pavement Performance
Austroads sponsored a technical research project Managing the Impacts of Rising Watertables and Salinity on Pavement Performance . The overall desirable deliverables were tools to assist road authorities to identify those sections of road that are…
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…
Assessment of Remaining Service Life of Pavements
This report documents the assessment of RSL of pavements where the RSL is confined in its estimation to the occurrence of the next major intervention either by rehabilitation or replacement. There are many measurable surface distress conditions,…
Development of HDM-4 Road Deterioration (RD) Model Calibrations for Sealed Granular and Asphalt Roads

Improved RD models for sealed granular and asphalt pavements are needed. Pavement performance history data from state road authorities and New Zealand (SRAs) were used for calibrating RD models. The calibration and refinement of RD models is…

Road Surface Characteristics and Crash Occurrence: A Literature Review

The starting point for this review was the recently-published Austroads Guidelines for the Management of Road Surface Skid Resistance. Skid resistance, which depends on both microtexture and macrotexture, is currently the road surface characteristic…
