Intelligent Pavement Management and Maintenance Intervention

Abstract

Pavements are designed and built to protect the subgrade by minimising rutting and to withstand weather conditions such as temperature and moisture. The current main challenges with pavement management are; accelerated deterioration due to the impacts of moisture ingress into the pavement layers, in particular due to high rainfall events, deterioration due to age, continued usage and traffic growth, continued increase in heavy transport, and quality of materials. Queensland has 25% of all Australian state-controlled roads, they are the state's largest publicly owned infrastructure asset. The road network is deteriorating due to age, continuous usage and the accelerating impacts of high rainfall and cyclonic events, in recent floods almost two thirds of roads were under water. Pavement instrumentation is being increasingly used in monitoring the performance of pavements and provides inputs to refine the design parameters to better reflect the local conditions and traffic loading. This research provides a base for long-term monitoring of the performance of in-service constructed pavements (asphalt surface on unbound granular base, asphalt surface on cement stabilised base, and chip seal surface on unbound granular base) under local conditions rather than relying on overseas research and/ or simulated environments. This will provide results reflecting local conditions in terms of design, materials, construction, traffic configuration and the environment including occasional pavement inundation. Consequently, there will be no need to utilise global calibration or adjustment factors.
