This paper provides the engineering benefits of the pavement management system (PMS) applied on the national highways in Korea for the last 20 years. 40% of service life of the pavements was enhanced, and 75% of rehabilitation cost per unit length was reduced. Two types of distress analysis methods based on ViziRoad and image process were evaluated. ViziRoad is easy and convenient to be used for general surveys. The image process approach provided is more reliabl, but is definitely time-consuming. To overcome these limitations, the grid image process method was proposed.
