Implementation of ground penetrating radar for network-lever pavement evaluation in Florida

In 1991, the Florida Department of Transportation (FDOT) initiated a study aimed at systematically implementing ground penetrating radar (GPR) for developing a statewide database of pavement layer thicknesses and base material type. Phase I of the study involved a demonstration of current GPR technology. This was achieved by conducting radar surveys on short pavement sections (0.1 to 1.5 miles long) established by FDOT and comparing the radar predictions with coring information. The results of these comparisons established the feasibility of using current radar technology for the purposes defined by FDOT.
