Heavy Vehicle Roughness Band Index: An Alternative Trigger for Pavement Rehabilitation
This report has developed a new index, the Heavy Vehicle Roughness Band Index (HVRBI), as a measure of ride quality for heavy vehicles. The HVRBI is intended for use by road asset managers as a trigger to initiate pavement intervention works…
Segregation and Degradation in Commercial SBS Binders

This study obtained an indication of the proportion of Australian commercially manufactured polymer modified binders (PMBs) liable to segregate, identifed suitable tests to measure segregation propensity and proposes measures to help prevent or…

Review of AASHTO Pavement Design Guide Performance Relationships

This report is an investigation on the development of the performance relationships used in the 2002 AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG). The primary objective of this investigation was to see if these relationships could be…

Measurement and Analysis of Dynamic Wheel Loads
This report explores the dynamic forces that heavy vehicles apply to road pavements and the effects that these forces have on pavement performance. The research focussed on identification of accurate and cost effective means to quantify dynamic…
The Scoping and Development of Probabilistic Road Deterioration (RD) Models

This report is a scoping document aimed at establishing how road deterioration (RD) models can be developed on a probabilistic basis. Deterministic RD models provide an average estimate to a future condition which is not necessarily likely to be…

Austroads LTPP and LTPPM Study - Summary Report 2010-11

Austroads Project AT1064 Long Term Performance Monitoring to Develop Consistent Performance Models has been running since 1994-95. A review of the analysis of US long term pavement performance (US LTPP) data used to validate the performance…

Improving Cost Allocation by Road Type

This report improves the current approach to cost allocation, develops incremental pricing, and develops direct user charging. This report includes analysis of the relationship between road use and expenditure without considering road condition; and…

Preliminary Methodology for Estimating Cost Implications of Incremental Loads on Road Pavements
This report documents the development of a preliminary set of load-wear-cost (LWC) relationships as a basis for estimating the short-run marginal road wear cost (SRMC) and long-run marginal road wear cost (LRMC) for the main road types comprising…
Review of the Traffic Speed Deflectograph: Final Project Report
This project was established to enable ARRB and Austroads member authorities to work with the RTA to develop an independent national perspective on the applicability of the TSD to Australian conditions and practices. As the TSD is a newly developed…
Update of Vehicle/Road Relationships Underpinning Road User Costs and Externality Costs

This publication reviews current methodologies for estimating vehicle operating costs (VOC). Recent Austroads work (TP1349) highlighted the need to improve the VOC-road roughness relationship. This report achieves this by conducting a literature…
