BridgeGuard Featured in Roads and Bridges Magazine (February 2010)

The article's abstract is as follows:

The reinforced concrete decking used to construct the bridges of our nation’s highways is continuously degrading by normal traffic and environmental exposure. This degradation is exacerbated in climatic regions where de-icing chlorides are used and in coastal regions where bridges are exposed to high airborne salt concentrations. Such deterioration requires new computerized non-destructive evaluation (NDE) test methods that aid in establishing maintenance demands. Here, the application of state-of-the-art infrared imaging sensors, supporting technologies, and sophisticated image processing techniques to perform bridge deck NDE is discussed. This is the first of two articles that explores IR technology as a contributing solution to the detection and mapping of bridge deck de-lamination.
