dc.descriptionAbstract: An evaluation of an impulse radar system for detecting cavities under concrete pavement is discussed, and field results are presented. It was found that a dual antenna mode of surveying was ideal for void detection. In this mode one antenna operated in a transceive role and a second, offset from the first, operated in a receive-only mode. This arrangement allowed a refraction-type profile survey to be performed, which enabled subpavement voids to be easily detected. Field trials were held at Plattsburgh Air Force Base, where 28 cavities were detected and mapped. Drilling holes verified that a cavity existed and allowed cavity depth to be measured. The cavities varied from 1.5 in. to 23 in. in depth and were up to 20 ft long.-
