Acoustic Emission (AE) Sensor Technology: Utilization for Non-Destructive Bridge testing

Hampton University Eastern Seaboard Intermodal Transportation Applications Center's (ESITAC's) stated goals are to utilize resources of the University in partnership with state and city governments, local transit companies, private industries, and regional universities to conduct research on current transportation problems facing Hampton Roads, provide students with special emphasis on minorities and women, the opportunities to pursue transportation careers and to advance U.S. technology and expertise in transportation that will provide safe, secure, efficient, and interconnected transportation systems. These goals incorporate U.S. Department of Transportation's (DOT's) stated priority for improving the safety of the nation's transportation system that includes safety of highway bridges. It is imperative to conduct research and utilize technologies that enhance highway bridge safety for achievement of such goals. Research on and utilization of non-destructive test and monitoring technologies is one of the focus areas in ESITAC's strategic planning. It is thus proposed to utilize non-destructive testing technology (NDT), in collaboration with the Virginia Department of Transportation's (VDOT's) District Structure and Bridge Engineering Department and its research arm the Virginia Council for Transportation Innovation and Research (VCTIR), for accurate, reliable and durable methods of structural health monitoring of highway bridges and to help prevent spread of structural failures. The bridge on I-164 at the Coast Guard Blvd. in the City of Portsmouth, built in 1991, was the subject of acoustic emissions (AE) research during 2010. Acoustic Emission investigations on the bridge on Route 164 at Coast Guard Boulevard were performed. The results of these investigations concluded beyond doubt the existence of strong AE activity in the bridge back wall. Further, the increase in AE activity was determined because of the freight train movement under the bridge. For the period of 2011, the bridge on I-64 at the Denbigh Boulevard in Newport News, Virginia, has been identified in consultations and discussions with VDOT's District Structure and Bridge Engineering Department and its research arm the Virginia Council for Transportation Innovation and Research (VCTIR). This bridge (Virginia Structure No. 2222, Federal Structure ID 20727), built in 1965 and reconstructed in 1977 crosses over I-64 and the CSX Railway. According to the latest available and 2009 AADT at Denbigh Boulevard is 29,000 vehicles per day; the truck percentage is 1%. The bridge is 864 feet long and 60 feet wide. The structural health monitoring is to involve metal and non-metal (e.g. concrete) bridge structural components using NDT of acoustic emission (AE).
