Ultrasonic Culvert Thickness Determination.

Abstract

This work describes a response to the need for a practical nondestructive method of measuring the thickness of culverts in situ established at the New York State Department of Transportation. The proposed method will provide data to realistically evaluate the remaining safe lives of the culverts. The technique developed uses the ultrasonic pulse echo technique with commercial off the shelf ultrasonic equipment and piezoelectric transducers in a bubbler configuration. The equipment consists of the 25DL precision thickness gage and the B 120 bubbler with V316-B, 0.75-inch PTF, 20MHz transducer--all by Panametrics. The user has to add a small water pump to provide continuous stream of water and a hollowed out rubber stopper to ease application of the bubbler to the culvert surface.
