Infrasense was in Missouri recently completing GPR, infrared, and visual scanning of bridge decks in the St. Louis area. Below are sample images in the early stages of processing. The final deliverables will present the infrared and visual imagery for the entire bridge deck with all areas of delamination, patching, and spalling mapped and quantified.
This past summer, Infrasense surveyed a bridge deck in La Crosse, Wisconsin using infrared for deck delamination detection according to ASTM D 4788 – 03. The equipment setup involved a dedicated vehicle mounted with a high resolution, distance triggered FLIR infrared camera synced up with a high-resolution visual spectrum camera. Both devices capture a whole…
Infrasense recently completed an internal research effort to assess the feasibility and accuracy of aerial imaging for mapping bridge deck conditions. The results of this study provided support for implementation on upcoming projects. The primary advantage of the aerial method is its efficiency. Data can be collected for hundreds of bridge decks in a single…
Infrared thermography is one of our primary testing technologies for Wisconsin bridge deck condition evaluations, and we are always seeking ways to improve our testing methods. In 2017, this research really took flight – literally! Infrasense has also been working with a national aerial imaging company to collect and analyze infrared and visual imagery from…
