Efficient inspection techniques for ageing infrastructures are in great demand. In this study, rainy induced acoustic activity, which has so far been treated as a nuisance event for acoustic monitoring, is ambitiously utilised to identify damages of RC slabs. Specifically, in-situ AE measurements of RC bridge slabs are conducted for a week. First, internal damages of the slabs are evaluated by both of AE activity and elastic wave velocity by means of AE monitoring and AE tomography. As for some representative locations showing each different damage estimated by the AE activity and the velocity, core samples are retrieved for the verification. In addition, AE activity induced by rain droplets in a short period of minutes are identified by an AE source location algorithm followed by computation on attenuation rate distribution. Through the evaluations, it was found that the distribution of AE sources induced by precipitation could reflect internal damage of RC slabs i.e., dense areas of source locations imply the intact or minor damage, while sparse areas of source locations suggest serious damage of RC decks. With this finding, the prompt decision making if the decks shall be replaced, repaired or left, which could not so far be readily implemented by other inspection techniques, would be reasonably conducted.
