Infrasense recently evaluated two bridge decks that make up a large viaduct carrying a major highway near Hartford, CT. A high-speed ground penetrating radar (GPR) survey vehicle was used to collect data without disrupting traffic. A limited number of cores were obtained at locations based on a preliminary analysis of the GPR data. The core data was used for finalizing the GPR deterioration quantities and maps.
, /PRNewswire-PRWeb/ — Infrasense was recently tasked with evaluating the condition of two bridge decks that carry traffic on a major highway near Hartford, Connecticut. The deck condition evaluations were carried out using a ground penetrating radar (GPR) vehicle system with multiple high frequency air-launched antennas. A distance measuring instrument (DMI) triggered the GPR data collection at a rate of 4 scans per foot of travel. The GPR data was also collected with synchronous high-resolution GPS data for accurate geospatial condition mapping.
The GPR dataset was …
