“…The fracture plane of the delamination acts as a small insulator and trapping the heat near the surface. During a summer day, these "hot spots" on the surface are generally 2° C to 5° C warmer than the surrounding solid concrete (Manning & Masliwec 1990) and those spots are clearly detectable by an infrared camera. Active method of infrared thermography uses external source of heating to observe the thermal differences attributed from embedded defects.…”

Non-destructive evaluation (NDE) has offered unprecedented utilize for bridge management body to monitor structural health. None of these evaluation methods can provide all the damage information (damage category, quantitative assessment) alone which is required for necessary repair activity and condition rating of structure. In most of the cases, the response of one evaluation method implies the presence of a defect among the multiple defects to which the evaluation method is sensitive. This paper is concerned with the combination of different non-destructive testing to find out the type of damage with the most efficient way. The different response (positive or negative) obtained from each combination and how it confirms the defect is shown through the mathematical set operation. Thus, this study would assist field investigator to ascertain the type of defect which subsequently aids to rate structure based on damage type

“…This study showed that structural problems can be identified and located quickly causing minimal disruption to traffic since the system is remote. A similar inspection technique is used in Canada [80] and at the University of Wisconsin-Milwaukee [136].…”
