Abstract

This paper deals with accuracy issues related to using ground penetrating radar (GPR) for determining the surface layer thickness of asphalt and concrete pavements. Additionally, tests were conducted to identify GPR's repeatability on dry versus wet pavements. Finally, an attempt was made to determine the number of actual field cores necessary to accurately postprocess radar data into layer thickness data. At this time, it appears that four calibration cores would be the optimum number of cores that would minimize errors. Journal of Transportation Engineering
