Automated Sounding

Advanced Bridge Deck Delamination Detection

Revolutionizing Traditional Sounding Methods

Rapid Automated Sounding (RAS) transforms the familiar and time-tested chain-drag method into a high-speed, automated solution for bridge deck delamination and debonding detection. By combining the reliability of traditional acoustic sounding with cutting-edge automation, RAS provides engineers with the familiar delamination and debonding maps trusted for decades with the added advantages of increased data density acquired  faster, and safer. Accuracy and consistency of results are increased by eliminating individual operator interpretation of the chain drag sounds.

The system works by continuously striking the deck surface using precision-controlled chains while sensitive microphones capture the acoustic signatures. Our proprietary algorithms analyze these sound patterns in real-time, instantly identifying the distinctive hollow sounds characteristic of delamination and debonding. What once required hours of manual testing and manual interpretation can now be completed in minutes at driving speeds up to 25 mph. 

Watch RAS in Action

Capabilities

High-Speed Data Collection
Complete bridge deck assessments at traffic speeds up to 25 mph, eliminating the need for lane closures and minimizing traffic disruption during network-wide inspections.
Automated Delamination Detection
Advanced acoustic processing algorithms automatically identify and map delaminated areas with greater consistency and accuracy than manual chain-drag methods.
Proven Methodology Enhancement
Built upon the industry-standard chain-drag technique that engineers have relied on for decades, but enhanced with modern automation, consistency, and data processing and reporting capabilities.
