This presentation will provide examples of how the basic NDE testing and evaluation methods are employed to inspect, evaluate, and extend the service life of existing highway structures. While the examples may not represent the exact procedures employed in each of the Northeast States, they represent typical applications of the NDE methods employed in many of the states. The presentation will be limited to the application of visual inspection, dye penetrant inspection, eddy current testing, ultrasonic testing, and radiographic testing. This is not intended to imply that new technologies such as acoustic emission, ground penetrating radar, and lasers measurements are not also used by any of these states.
