Abstract: Safety inspections of infrastructure rely on visual inspections and hammering inspections by inspectors. However, there is a problem that inspection results vary because of differences in the technical level of inspectors. In order to solve these problems, we propose an inspection method and preventive work using coating type resin sensor and an infrared camera. The non-destructive evaluation technique by thermography is increasingly being used as a tool for the maintenance of concrete structures. In most applications, the evaluation of only the location and shape of defects on planes is expected, therefore, no method has been developed for evaluating the depth of defects. After the application of infrared reactive resin, the target area, and thermos graphics are taken sequentially. Then, analyses the temperature curves obtained at each pixel during cooling defect states in different parts of the temperature distribution by Fourier transform. This particular temperature change is related to the size of the defect. Approximately 10% of aluminium powder is mixed in the applied gel resin, and this aluminium powder has the property of concentrating due to its specific gravity in areas damaged by compression failure or floating. In this paper, we report on the technology related to the identification and size measurement of defects in infrared reactive resin, and the effect of preventive work to prevent the scattering and collapse of defects caused by destruction.
