Establishing Deterioration Models for Local Roads

This paper describes how Local Government Authorities across Australia have adopted a variety of Pavement Management Systems (PMS) for local roads to guide the development of pavement maintenance, rehabilitation programs and the appropriate allocation of road funding on their road networks. Many practitioners managing local roads have difficulties with their PMS packages, as the prediction of pavement performance does not accurately match actual pavement conditions. This is due primarily to the pavement prediction models used in existing PMS being based mainly on the performance of overseas pavements and therefore not necessarily accurately predicting pavement performance under Australian conditions. Pavement deterioration models are a critical component in any PMS and accurate models are essential in order to better manage roads for both strategic (network level) and maintenance works (project level) and gain greater value from the funding available. With appropriate deterioration models asset managers can have greater confidence in forecasting future pavement conditions, establishing maintenance programs and substantiating budget requirements. In order to develop appropriate deterioration models for local roads in Australia the ARRB Group (ARRB) initiated a study to establish a large number of sites across Australia on which pavement performance is to be monitored over 5 years. The sites selected are aimed at being representative of local road pavements covering a range of roads types, including both sealed and unsealed roads, climatic conditions, traffic loading, soil types, construction techniques and maintenance practices across Australia. The paper outlines the study being undertaken by ARRB. It describes the method used to gain national support for the study, selection of appropriate pavement performance indicators, collection methods employed, the number of monitoring sites established in each State/Territory and some interim results to date.
