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…

The purpose of this report is to provide an overview of the Pavement Maintenance database creation, including documenting the cleaning and filtering of the results. The analysis was performed on SA, VIC, NSW and QLD datasets to identify…

This report presents a review of the available structural design methods for foamed bitumen pavements, as a first step in the development of thickness design procedures. Six design procedures were found in the literature, most of them based on well…

This report presents the test results of bitumens used across different states in Australia. This database will be useful in identifying possible trends in properties associated with recent changes in the manufacture of Australian bitumens and…

This report is the second in a series which examines the properties of Australian bitumens from around Australia. Thirty-one bitumens from around Australia were subjected to a range of test procedures. These included viscosity measurement at a range…

A significant factor contributing to the establishment of Australia’s large network of surfaced roads has been the successful application of sprayed sealing technology, including the selection of treatments, design of the treatments and application…

Austroads Project No: TT1358: Review of Structural Design Procedures for Foamed Bitumen Pavements proposed a method for the thickness design of foamed bitumen to be adopted in principle by Austroads. Foamed bitumen is a mixture of hot bitumen, water…

This report provides a review of research and developments in skid resistance measurement methods. The objective is to provide up-to-date information on the major issues (e.g. variability) involved in skid resistance measurement.

The National Transport Commission (NTC) and Austroads are developing Performance Based Standards (PBS) which will augment prescriptive regulations for heavy vehicle mass, dimensions and configuration.

Current skid resistance monitoring programs and investigatory limits used in Australia were based on systems developed in the UK where the climate, traffic intensity and network configuration are very different. These do not necessarily suit…
