Case Studies of Failures and Successful Applications of Countermeasures Using Non-Destructive Testing for Long-Term Bridge Maintenance

Abstract

 In our efforts to implement more reliable and efficient maintenance for the long-term repair plan of bridges in Ota Ward, non-destructive tests were conducted on a bridge slated for repair to gather essential design data. Unfortunately, due to limitations in the applicability of certain non-destructive test to the specific structure, the test results did not accurately reflect the actual condition of the bridge, as was discovered during the subsequent repair process. To rectify this issue, additional non-destructive tests were conducted. This paper presents these case studies of both successful and unsuccessful applications of non-destructive testing in bridge maintenance, and outlines key considerations for those implementing such initiatives.
