Application of Infrared Thermography in Pavement Inspection

Infrared thermography (IRT) is an effective non-destructive testing method in the field of concrete and asphalt pavements monitoring. IRT is used to have an initial evaluation of the surface and near surface of pavements in a very time effective manner. The effect of the depth of delamination inside concrete pavement on infrared thermography technique is being studied. It is also suggested by our group that there is a correlation between the surface crack profile on the asphalt pavements and its temperature. Finally, a full laboratory study is being conducted to experimentally quantify the effects of weather conditions on IRT.
