Acoustic Emission Safety Monitoring of Intermodal Transportation Infrastructure

Safety and integrity of the national transportation infrastructure are of paramount importance and highway bridges are critical components of the highway system network. This network provides an immense contribution to the industry productivity and economic competitiveness. The infrastructure maintenance efforts must ensure a safe, timely, and reliable means of determining possible structural failures without undue disruptions to the traffic flow. As part of the National Center for Intermodal Transportation and Economic Competitiveness, with the assistance of the Virginia Department of Transportation, the application of the acoustic emission non-destructive testing methods is investigated for detecting and assessing structural conditions of the steel girder highway bridges. Acoustic emission can be used to identify suspected areas of the structure and helps to evaluate whether any further testing and analysis is warranted. A candidate bridge site, the interstate I-664 bridge crossing in Newport News, VA, was selected for this research.
