Student Involvement This project will support a M.S./Ph.D. student (1/2 time) for 3 years  to conduct the research and testing.
Project Objective To train state transportation agency staff in thermographic non-destructive inspection and evaluation techniques and to draft a model practice so that these techniques can be used to  improve concrete highway bridge inspection efficiency which will result in better infrastructure and improved public safety.
Project Abstract Field testing and evaluation of thermal imaging to evaluate the reliability of the technology, validate previously developed guidelines for field use, and evaluate implementation barriers.  Participating states 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.  The research team, in cooperation with the states, will conduct a series of focused field tests that include field verification of results.  These field tests will seek to quantitatively evaluate the capabilities and reliability of the technology under field conditions to validate and improve the guidelines, and support practical implementations of the technology.  The outcome of the research will be a new inspection technique for improving bridge safety and identifying repair and maintenance needs.
Anticipated Benefits Implementation of  this innovative new technology will improve state transportation staff efficiency and technical competence in conducting bridge inspections, which will result in safer bridges.
