The New Zealand Transport Agency recently carried out a nation-wide screening of state highway bridges for scour and other bridge waterway risks. This paper outlines lessons learned from the implementation of the screening programme and reviews the…

The summer of 2010 / 2011 represents an extreme event. The majority of Queensland was declared a natural disaster zone as a result of the damage caused by non-typical flooding and cyclones throughout the State. It is estimated $4.5 billion dollars…

Alkali aggregate reaction, or AAR, is one of the major causes of degradation in older concrete structures. AAR occurs when the hydroxide ions that exist in the cement react with aggregate, often with water acting as a catalyst to speed up this…

In January 2011, Queensland experienced a rain event, unlike any other in recent history. Unprecedented damage occurred to the infrastructure in many parts of Queensland. After the flood event, Aurecon was commissioned to assist in flood damage…

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…

There is a need to develop models to predict the horizontal forces applied by all combination vehicles with axle masses above the current allowances to assist in the prediction of the resulting pavement surface wear.

The impact of heavy vehicles on…
