Due to the nature of the Municipal and local road asphalt pavement, the evaluation procedure and the maintenance budget estimation procedure in the excessive crack and the excessive rutting section are indispensable. In this study, we propose Maintenance selection procedure suitable for local roads using modified local pavement condition index (modified LrPCI) which can evaluate the present state of asphalt pavement according to road grade, traffic volume and importance of local roads. We have developed an algorithm that can predict the maintenance budget for repairing by the proposed procedures. According to the maintenance estimation procedure proposed in this study, it is possible to obtain the average LrPCI correlation with the repair cost of the local road asphalt pavement. From this correlation, it is possible to calculate the approximate scale of the maintenance cost required for the quantitative performance management through the road management system of the local roads. Therefore, the developed algorithm can be used as a basis for estimating the appropriateness of the local government budget and can be used by local governments to forecast maintenance costs to manage local road asphalt pavement on a goal management basis.
