The Evaluation of Pavement Repair Policy Based on Enormous Data of Road Surface Conditions

The pavement repair policy is planned and implemented based on the knowledge of pavement engineering, and improved constantly by reflecting the experience and knowhow that have been accumulated by field engineers for many years. However these cannot be evaluated scientifically, it is also difficult to scientifically discuss the appropriateness of pavement repair policies. In recent year, more effective and economical pavement repair policies are demanded, and scientific evaluation is necessary. In this study, the authors estimate more reliable deterioration curve and expected lifetime of road surface statistically, by using more than 200,000 inspection data. Furthermore, the authors calculate the life cycle cost (LCC) for the pavement repair policy, and investigate the optimal repair policy by evaluating the risk and the LCC. In addition, the authors discuss (1) the evaluation indices for managing the road surface for which drainage pavement is increasingly used, (2) the optimal repair strategy, and (5) the method to determine the order of repair, by simulating the process of the deterioration and repair, targeting the roads managed by the expressway management company of Japan.
