Infrared Thermographic Inspection of De-Bonding Between Layers of Airport Flexible Pavement

Infrared thermography is widely used to detect the positions of defects within the concrete piers of roads and railways. This method is based on the surface temperature difference between bonded and de-bonded areas. This paper presents the results of field trials and thermal analysis conducted to verify the applicability of the infrared thermographic inspection method to detect de-bonded area between asphalt concrete layers, and the following conclusions are obtained. (1) De-bonding at the depth of 40 – 70 mm from the surface of pavements can be found by infrared thermography. However, the depth of de-bonding which can be detected by the infrared inspection method changes with the weather conditions. (2) The amount of solar radiation and the air temperature difference between day and night affect the surface temperature difference due to the existence of debonding.
