Infra-red thermographic analysis of bridges
Infrared thermography has various applications within the civil engineering areas. One such application was explored in this paper. A survey was carried out to investigate the presence of temperature anomalies that may indicate the existence of delaminations on the underside of a concrete bridge deck. More bridge spans were tested than originally planned due to the efficiency of the infra-red thermographic technique. From the survey conducted it can be seen that delamination can be identified using infra-red thermography, even though the survey conditions were imperfect. Two previously unidentified areas of delamination were found, one of which was 'tap' tested and confirmed as an area of delamination. All but one of the areas of delamination which were previously found using the 'tap' testing technique, were identified by infra-red thermography. The area not detected was close to the edge of the slab and subject to local sunshine. Some of the areas identified were as small as 20 cm in diameter. The difference in the temperature of the delaminated areas compared with the non-delaminated areas was approximately 0.2 deg C to 0.3 deg C.
