Abstract
This paper describes the physical check method and remaining life prediction method for an aged RC-T girder bridge and the verification of the remaining life prediction results based on either close visual inspection data or concrete core test results obtained from field tests. A bridge management system (J-BMS) was applied to evaluate the safety indices and remaining life of the bridge based on these test results. The remaining life of the bridge was quantitatively estimated by applying the J-BMS with field inspection data, and the remaining life prediction results were verified by using the strength, elastic modulus, carbonation depth, chloride ion concentration, and other results obtained from the collected concrete cores.
