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…

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…

The impact of heavy vehicles on pavement surfacings needs to be quantified over typical surfacing lifecycles. Failure modes of surfacings are often horizontal shear-stress induced rather than vertical load
