Detection of Voids Underneath Concrete Pavements Using Infrared Thermography
This report describes preliminary theoretical and experimental investigations of a technique for void detection beneath concrete pavements. The technique is based upon use of infrared thermography and the hypothesis that the surface temperature of the pavement over the void is slightly different than the surface temperature of pavement in contact with the base material. Experimental investigations were conducted on a concrete slab 12 ft x 21 ft x 8 inches thick which was cast at Balcones Research Center. Three voids of known locations and dimensions were created beneath the slab. Thermistors were installed at various locations in the concrete slab and in the soil beneath the slab to monitor air, ground, and soil temperatures. An infrared scanning camera system was installed on a truck-mounted frame.
