Field Evaluation of Thermographic Bridge Concrete Inspection Techniques

The goal of this research is to develop new technologies for the condition assessment of concrete to help ensure bridge safety and improve the effectiveness of maintenance and repair. The objectives of the research are to: Quantify the capability and reliability of thermal imaging technology in the field; Field test and validate inspection guidelines for the application of thermal imaging for bridge inspection; and Identify and overcome implementation barriers. The project will provide hand-held infrared cameras to participating state Departments of Transportation (project partners), train individuals from these states in camera use, and conduct field test of the technology. The reliability of the technology will be assessed and previously developed guidelines for field use will be evaluated through systematic field testing. Project partners will be provided training and hardware for testing within their existing bridge evaluation programs, to identify implementation challenges, evaluate the effectiveness of guidelines, and assess the utility of the technology for bridge condition assessment. A series of field tests that include field verification of results will be conducted by the project partners in cooperation with the research team. These field tests will seek to quantitatively evaluate and verify the capabilities and reliability of the technology under field conditions. These data will be used to validate and improve the guidelines and support practical implementations of the technology. The outcome of the research will be a new tool for improving bridge safety and identifying repair and maintenance needs.This report addresses the training phase of the project, during which states participating in the pooled fund were training in the underlying theories and procedures for implementing infrared thermography for the condition assessment of bridges. The primary technology developed under this portion of the study was the training modules and slides, which are included herein as an appendix to the report.
