Abstract (in Japanese) (See Japanese page) 
(in English) In this report, the measurement results of 2016 and 2017 on the lower surface of the floor slab of a large bridge were compared, and the reproducibility and the progress of degradation using the noncontact acoustic inspection method were confirmed. About 1 year passed since the experiment in 2016, it was expected that some change occurred in the measurement target area. As a result, it was confirmed that internal deterioration in the measurement target is progressing more than 2016. From the above, it was confirmed that the reproducibility and progress of deterioration can be grasped in this method.
