Infrasense recently completed ground penetrating radar (GPR), infrared thermography (IR), and high-resolution video (HRV) data collection on a pair of decks in southeastern Virginia. These datasets will be used to quantify and map rebar-level delaminations, corrosion activity, spalling, and patching. Additional testing, including targeted coring, chloride sampling, and half-cell potential (HCP), will be carried out…
Infrasense recently evaluated the condition of 41 bridge decks located in northcentral Wisconsin. The deck evaluations utilized vehicle-based infrared thermography, high-resolution video, and ground penetrating radar. All testing was carried out at a rolling speed, which allowed for spot verification via hammer sounding. Following the field surveys, the data was transferred to Infrasense’s headquarters in…
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…
