Infrared thermography (IRT) is an effective non-destructive testing method in the field of concrete and asphalt pavements inspection. IRT is used to have an initial evaluation of the surface and near surface of pavements in a very time effective manner compared to other types of nondestructive testing (NDT) methods. Different aspects of IRT and its use to assess surface and subsurface defects in different types of pavements are being studied and evaluated in our research group. The effect of the depth of delamination inside concrete pavement on IRT technique is being studied. It is suggested by our group that there is a correlation between the surface crack profile on the asphalt pavements and its temperature, which will help us to evaluate pavement performance condition. Finally, a full laboratory study is being conducted to experimentally quantify the effects of weather conditions and surface coating on the ability of IRT to assess surface cracks on both asphalt and concrete pavements
