RIS Ground Penetrating Radar (GPR) Systems can accurately and nondestructively “see” through solid pavement materials, such as asphalt, concrete and soil to detect subsurface objects and determine the condition and thickness of the material examined. The IRIS is an ideal technology for detection of bridge deck delaminations, voids, subsurface moisture accumulation and the thickness of asphalt pavement layers…All at highway speeds!
