Abstract
This paper investigates the reasons of why the amount of non-restored failures and damages have been steadily increased as time passes by. This trends may be attributed to the diversity and complexity of initialization processes of failures as well as insufficient governance of rehabilitation/maintenance management. Based upon the data base of failures and damages, which have been detected by inspection of expressway facilities, the paper analyzes the statistical aspects of failures and management issues, which are typically characterized by the following factors: i.e., the initialization time of failures, the presence of causality that failures spread and amplify to one another, the influence of maintenance activities on the following occurrence of failure, the influence of the accumulation of non-restored failures on the judgment to restore, and the determinative factors for decisions to restore. The paper tries to suggest the necessary conditions enabling infrastructure management bodies to control the failure occurrence process. Also, the paper underlines importance of the managerial methodology which is designed to keep the amounts of non-restored failures in sufficiently lower levels through time.
