PROBABILISTIC ASSESSMENT OF THE SUBSURFACE CONDITION OF BRIDGE DECKS USING GPR
A probabilistic methodology for assessing the condition of bridge decks using ground penetrating radar (GPR) is presented. GPR is a subsurface sensing and imaging technique that provides quantitative information about features inside deck materials. Although GPR is already in use by many transportation agencies, the need still exists for a definitive determination of its accuracy. This study considers important uncertainties and probabilistic modeling of 2 measures: rebar reflection amplitude and wave traveling time. The developed methodology is illustrated by a case study that uses real-world data and is designed to establish conformity of GPR measures to the "ground truth." Key findings and conclusions are offered and discussed.
