Performance modelling is an asset management tool used to quantify or qualify the performance of a bridge within the context of the overall bridge network. Performance modelling techniques include the use of performance indicators and deterioration…

This report provides a generic framework for the management of road-related assets. In recent times, road agencies have made a shift from being road builders to road managers. This change has ensured that road agencies need to accept responsibility…

Failures of traffic signals can lead to crashes and loss of productivity. As the road network gets more congested, the sustained operation of traffic signals becomes even more critical. The effective management of traffic signal assets therefore…

The work documented in this report demonstrates the use of existing Austroads deterministic road deterioration (RD) models in a probabilistic approach to estimate the possible predictions for the dependent variables of these models. This approach…

This report provides a brief state-of-the-art review of current traffic speed deflectometer (TSD) practice based on information gained from attending the deflection at road traffic speed workshop held in the UK in June 2012.

The current state of…

Bitumen, an important component used in road construction in Australia and New Zealand, is manufactured from a finite, non-renewable crude oil resource. A number of commercially available alternative binders and bitumen extended binders have been…

This report presents research outcomes of Austroads project AT1488: Improving skid resistance measurement, carried out from July 2009 to June 2012. The main goal of the project was to improve the understanding of variability associated with skid…

This report documents the outcomes of an Austroads project which considered the asset management implications of the new Safe System approach and investigated what implementing a Safe System would mean for asset managers. The report provides a…

This report presents recommendations for the creation of a database to support heavy vehicle road safety performance indicators. It aims to assist state road agencies, police and other stakeholders identify and collect the minimum datasets required…

This report provides a worked example for developing skid resistance investigatory level guidelines.

The worked example is sourced from Main Roads Western Australia (MRWA) and relates to texture measurement as a surrogate for skid resistance. A…
