ABSTRACT: Ground penetrating radar (GPR) and the portable seismic property analyzer (PSPA) have been extensively used in the past two decades for
monitoring, quantifying, and mapping the deterioration of bridge decks. Using
PSPA and GPR ensures regular monitoring of bridge conditions, leads to the
early detection of deterioration. This research is to address the condition of
August A. Busch bridge deck owned by the Missouri Department of Conservation.
Visual inspection, GPR, and PSPA data were acquired on the bridge deck. Over
90% of the bridge deck was in fair to good condition with an average
compressive strength of over 2500 psi. GPR data showed no indication of
significant deterioration. The overall bridge deck was determined to be in fair
to good condition.
