In order to determine a quantitative preventive maintenance program which is lacking in the Experience method, both the development history and the research status quo of the preventive maintenance technology are deeply investigated, and a design procedure of the preventive maintenance program is proposed based on the successful experiences in Guangdong Province for many years. Moreover, the methods of hierarchical clustering and dynamic clustering are introduced into the proposed procedure, and some specific steps of pavement segmentation are provided. The proposed procedure has been adopted to design and implement a practical preventive maintenance program of a freeway in Guangdong Province in 2007. The results indicate that the proposed procedure and the clustering methods are all effective and feasible.
