Project description

Until recently, there were no methods for structural health monitoring of new reinforced concrete bridge decks, or diagnosis of existing ones, with the sensitivity to detect the early onset of various types of deterioration. Past and current Nebraska Department of Transportation (NDOT) - UNL collaboration on this topic by the research team has developed a novel technique and succeeded in answering this gap. This method involves leakage of ultrasonic guided waves (UGW). In this method, the waves leaked from the wave guide (steel rebar) are detected by an array of receivers (R) placed on the surface of the concrete.
