A STUDY ON EVALUATION METHODS FOR REMOVAL AND CONTINUED USE OF EXISTING BRIDGES IN BRIDGE MAINTENANCE PLANS

Abstract

 Aging is progressing, especially in large numbers of road bridges built in response to the rapid increase in road traffic demand during the period of high economic growth. The Ministry of Land, Infrastructure, Transport and Tourism says consolidation and removal as one of the measures to cope with aging could be an effective means overall, as well as delays in starting repairs due to lack of maintenance costs and lack of engineers. However, specific evaluation indicators for determining consolidation and removal have not yet been provided. Therefore, in this study, evaluation methods and evaluation items for judging consolidation and removal are discussed and proposed, and the evaluation categories are defined step by step, and the potential for removal and continuous use is evaluated.
