Infrasense recently evaluated the condition of 20 bridge decks primarily located in St. Louis and St. Joseph, Missouri. The deck evaluations were carried out using vehicle-based ground penetrating radar (GPR), infrared thermography (IR), and high-resolution video (HRV) equipment operated at driving speeds. The GPR and IR methods are carried out according to ASTM specifications D6087-08(2015) and D4788-03(2013), respectively.

Following the field surveys, the data is transferred to Infrasense’s headquarter
