In maintenance of aging concrete structures, it is necessary to detect delamination damages for preventing concrete block spalling that may cause third party damages. In the case of the concrete structure in the high place, there are some difficulties in nondestructive inspection, such as construction of scaffoldings in short range inspection or accuracy problem in remote inspection. Passive infrared thermography method has been effectively applied to detect delamination damages in concrete structure. However accuracy of defect detection is deteriorated for underside of bridge where sunlight cannot reach directly. In this study, a new inspection system was developed for underside of concrete deck using active scanning heating equipment and small infrared camera developed for UAV.
