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…
Austroads LTPP and LTPPM Study: Summary Report for 2005/06
This report presents the summary of project activities conducted in 2005/06. A number of suitable sealed granular pavement sites were identified across Australia for inclusion in the LTPP study. Interim WE models were developed. An improved revised…
Application of the Analytic Hierarchy Process in Road Asset management: User Manual
This manual provides guidance for the application of the analytic hierarchy process (AHP) as a decision support tool in road asset management. AHP is a multi-criteria analysis technique that allows trade-off between objectives with different…
Service Life of Pavements: Context, Review and Definition of Terms
The project was aimed at providing an understanding of 'remaining service life' as a concept and definitions of key terms such as 'design life', 'service life', 'remaining service life (RSL)', 'designated level of service', and 'threshold distress…
Managing the Impacts of Rising Watertables and Salinity on Remaining Pavement Life: Report of 2005/2006 Activities
This report comprises a technical review and update on new knowledge about salinity impacts and pavements. A review of recent literature and research outputs has indicated that there are knowledge gaps in the area of how salinity affects pavements…
