Abstract
As the road has recently been improved sufficiently, the road administrator must schedule the reasonable maintenance planning for the road bridge, the road tunnel, the road pavement and etc. Because we must have the best result in the limited maintenance budget which is invested for those road belonging's constructions. In this paper, we take up the prefectural highways pavement, and examine into the pavement maintenance planning with the help of the pavement maintenance management system that offers the prediction formula, the priority, the maintenance operation, the maintenance control level and so on. In this paper, we explain this system. Then we project the most appropriate longterm pavement maintenance planning which is simulated with the help of this system.
