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…
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…
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…

Comparison of the US and Australian Long Term Pavement Performance (LTPP) Data on Asphalt Pavements
This report compares the deterioration of two pavement groups in the US-LTPP program (GPS1 and GPS2) with that of the Australian LTPP GPS1 and GPS2 pavement groups. For the non-freezing group of the GPS1 pavements, the US sections had similar…
Freeway Traffic Flow Under Congested Conditions: Literature Review
This report provides a literature review on the analyses of the flow breakdown process on a freeway. It begins with the basic freeway flow theory and automatic freeway control tools now in operation. The factors that contribute to flow breakdowns on…
