Structural analysis has progressed a long way from hand calculations and the use of distribution factors. From the first computer methods, grid and grillage analysis techniques evolved, leading through progressive enhancements to the advanced 3D…

Some old bridges in Australia were constructed with a deck system consisting of non-composite concrete slab over steel girders. The paper herein presents the methodology for structural retrofitting/ strengthening of these existing bridges based on…

The economic vitality of Auckland depends upon the movement of people and freight around the city’s motorways and the Auckland Harbour Bridge (AHB) is a crucial component of the network. Traffic loads derived from weigh-in-motion (WIM) data measured…

There are 5094 bridges and bridge size culverts under the jurisdiction of the Roads and Traffic Authority (RTA) NSW. More than 50% of these bridges were built before 1976 and design load was significantly lower than the T44 design load in accordance…

More sustainable bridge infrastructure can be achieved by eliminating costly and unnecessary replacement or overly zealous upgrading of ageing bridges. Estimates of current safety of bridges or their remaining service life are critically dependent…

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 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…
