Formatted abstract

As asphalt pavements age and deteriorate, the need for corrective measures to restore safety and rideability increases. A lot of Councils are operating on current budgets and are not generally aware of their future liability for recurring maintenance as their infrastructure ages. Funding for rehabilitation and maintenance of these pavements is not likely to keep up with the demand, requiring a move to the most cost-effective methods when patching distressed areas to be adopted. The repairs will also be expected to survive longer and carry more traffic loading.  

The effectiveness of pavement maintenance verse rehabilitation works is best judged by analysis of their life-cycle performance. This involves the analysis of the serviceability and structural condition of the pavement with and without proposed interventions, and the associated economic performance through the pavement life. As the future condition and costs of a current pavement network are not known, we need to use models to predict these, based on the performance of similar pavements that data has been collected for through their life-cycle.  

We have decided to use road roughness survey data to formulate a model for asphalt pavement deterioration throughout its life-span and the pros and cons for the alternative works options, those being maintenance and rehabilitation, at different stages in pavement life and for a variety of pavement failures.
