The number of highway bridge has been doubled for last 10 years. It is because many new highway routes has been completed since 2000. As a result, the maintenance cost of highway bridge has been increased as well. Therefore, to predict the long-term maintenance costs, there is a need for a method. To solve this problem, various studies about the life cycle cost analysis was conducted.
Maintenance costs for members of the highway bridge is quite different to each other. Therefore, all the elements that are managed by the same proportion is inefficient. In this study, the distribution characteristics of maintenance costs for members of the highway bridge were analyzed using research data and highway bridge maintenance system data.
