Rapid Automated Sounding
Traditional sounding is an industry-standard, non-destructive method for locating delaminations on bridge decks. The Rapid Automated Sounding (RAS) system was developed to replicate and improve on this tried-and-true test. By automating traditional sounding, Infrasense provides an updated version of delamination maps that have been used for decades by improving cost, speed, safety, and accuracy.
The RAS system detects delaminations by continuously striking the deck using chains and recording the sound using microphones. Proprietary algorithms process the audio recordings and detect the distinct sound produced by delaminations. The test is performed at speeds up to 45 mph and is completed in seconds, drastically reducing the impact on traffic and making network-wide deck inspections possible.
