Thermographic Inspection Technologies Pooled Fund Study - Phase II

This project is a Missouri led Pooled Fund. The initial pooled fund research project for Thermography Technologies developed methodologies and procedures to utilize infrared (IR) cameras under field conditions. A combination of field testing by participating State Departments of Transportation (DOTs) and a laboratory study was conducted. Guidelines were developed for state practitioners to follow when using the Thermographic Imaging for inspection of bridges. This project represents Phase II which will provide for implementation guidance within the participating states. The objective of this research is to validate and improve upon the guidelines developed during phase I. Each state will receive a camera and training so they can utilize the technology as part of their inspection process. The states will then provide the images and results to the researchers in comparison with traditional methods of inspection. Quarterly Progress Report (Jan-June 2013): This past quarter, verification testing took place in Pennsylvania, Wisconsin and Texas. Cores were taken in the bridge decks and confirmed what the inspectors were finding with the camera. A training course was completed in Ohio where an additional 11 people were trained on the use of the infrared camera. Work is almost complete on an "app" that lets the user know if the weather conditions are favorable for using the thermography camera. The research team has also been working to model the thermal response for challenges such as water or epoxy-filled delaminations as well as revisions to the guidelines for wind speed recommendations. Additionally a project budget extension was completed this past quarter to update the contract for 4 additional states that joined the pooled fund. Quarterly Progress Report (Oct-Dec 2013): On November 8, 2013 the research team conducted a test phone interview with Iowa DOT to ascertain how IDOT is using the IR camera, the strengths and weaknesses of IR for analyzing highway bridge concrete defects, and to ask if the state DOT had any suggestions for additional or alternative IR techniques or equipment that could improve IR camera utility through this project. A similar phone interview will be conducted with other participating states. On November 19 & 20, 2013 the research team and New York DOT conducted verification testing of IR imaging. This past quarter the project data site was also updated so that you can sort through the bridge photo entries by state, bridge ID number, location or element type.
