In this report, in the RC bridge located in the coastal area of Okinawa Prefecture, re-deterioration has occurred on the lower surface of the main girder which has repeatedly been subjected to cross-section repair in the past. I confirmed the power. As a result of the test, it was confirmed that the residual load capacity against actual traffic was sufficiently high, and had sufficient reinforcing effect.
