Thermographic NDT technique using an active thermal stimulation method was applied for the detection of delamination defects in concrete structures. An oil heater, which can apply heat flux to the objective body by radiation and convection heat transfer, was employed for active heating. Evaporation cooling by water spray was used for active cooling. Preliminary experimental investigations were carried out for concrete specimens with artificial delamination defects. It was found that delamination defects can be detected from the thermal images, in which localized high or low temperature regions appeared above the delamination defects. Proposed technique was applied for the inspection of actual delamination defects in the concrete railway bridges. It was found that the defect shape was clearly estimated from the localized temperature region appeared in thermal images under active thermal stimulation.
