GPR Evaluation of 236 Bridge Decks Throughout Montana

Infrasense carried out high-speed GPR condition evaluations on 236 decks throughout the state of Montana. Of the 236 decks surveyed, 165 were selected for a Level 2 analysis, which involved detailed mapping of the concrete deterioration. Additionally, rebar depth contour plots were created which facilitate more accurate deck repair volume calculations. Per the request of…

Infrasense Carries out Ground Penetrating Radar (GPR) and Infrared Thermography (IR) Condition Surveys of 17 Bridge Decks in Wisconsin’s North Central Region

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.…

Evaluation of Pascack Road Bridge Deck in NY using Ground Penetrating Radar (GPR)

In order to facilitate rehabilitation planning of an asphalt overlaid bridge deck carrying I-87 over Pascack Road, ground penetrating radar (GPR) was used to quantify and map concrete deterioration. The GPR data was carried out at driving speeds using a vehicle-based system, so no lane closures were required. In addition to being deployed at driving…
