Infrasense is back in Wisconsin collecting Infrared and GPR data on a large number of bridge decks throughout the state. We are looking forward to completing projects scheduled throughout the Midwest over the next few months!
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 completed a ground penetrating radar (GPR) survey to map the reinforcing steel layout and depth along the underside of a bridge deck in Fond du Lac, Wisconsin. The rebar map will be used by the client to assess the load carrying capacity of the structure and ultimately to update the load rating. The GPR…
Infrasense, through multiple work orders, has conducted infrared thermography (IR, per ASTM D4788-03) and ground penetrating radar (GPR, per ASTM D6087-08) surveys on over 800 decks representing 7.7 million sq. ft. in Wisconsin’s SW, NC, NW, NE, and SE regions. In 2017, Infrasense conducted surveys on over just over 130 decks. All GPR data collection…
Infrasense completed a Pilot Study to establish a method for measuring the void space between a decorative fascia wall and a mechanically stabilized earthen (MSE) retaining wall using GPR. Ground-coupled GPR antennas were used to test the abutments of multiple bridges in Green Bay, where these MSE retaining walls are used in the design of…
This past summer, Infrasense conducted a multi-faceted non-destructive survey and report for 17 bridge decks in Wisconsin DOT’s North Central Region. The project provided the client with a comprehensive set of condition results to facilitate a data-driven approach to programming their bridge inventory. Surveys were performed at normal driving speed with no disruption to traffic.…
