Regular testing of concrete railroad cross ties is critical to the safe operation of a high speed rail system. Traditional monitoring of the condition of railroad cross ties has been limited to visual inspection. NDT uses sonic/ultrasonic techniques for reliable scientific testing of the structural performance of railroad cross ties. We determine the integrity and condition of each tie by recording and measuring the velocity that acoustic waves propagate through prestressed concrete railroad cross ties. The measurements detect and quantify internal flaws that visual inspection might miss because of the limited exposed tie surface.
