GPR Investigation of Bridge Deck, Willow Springs, Missouri

The presence of surface "honeycombs" suggested that a segment of the concrete deck of Bridge A6329, Willow Springs, Missouri, was not properly vibrated. University of Missouri, Rolla, will acquire 75 ground penetrating radar (GPR) profiles across the suspect area of the bridge (and other sites for comparison purposes) to determine if concrete in the suspect area contains unacceptable concentrations of air-filled voids (entrapped bubbles). The resulting GPR profiles are presented as time-sections.
