Vehicle-Mounted Bridge Deck Scanner

The objective of the proposed research project is to develop a vehicle-mounted Bridge Deck Scanner (BDS) based on nondestructive evaluation (NDE) technologies for the rapid and quantitative internal evaluation of reinforced concrete bridge decks, using a combination of Impact Echo (IE), Automated Acoustic Sounding, Spectral Analysis of Surface Waves (SASW), and Slab Impulse Response (SIR) methods. This research will explore and implement rolling contact and noncontact transducers used by all four test methods in the BDS. Where technically feasible, airborne transducers will allow for rapid testing and eliminate the problem of coupling between the sensors and the surface of bridge decks. The final product of the research will be a vehicle-mounted prototype system. This prototype system is envisioned to have multiple rolling contact sensors and/or airborne noncontact transducers with different types of sources to perform IE, Automated Sounding, SASW, and SIR tests. This NDE system will be designed to be easily attachable and detachable from any vehicle (e.g., from the ball on a truck hitch). Results from the four NDE tests address different aspects of the internal conditions of concrete decks. The scanning feature using a vehicle will expedite the field-testing process and allow near-continuous testing along the bridge deck by the BDS system.
