Abstract:

Remote sensing technologies allow for the condition evaluation of bridge decks at near highway speed.

Data collection at near highway speed for assessment of the top of the concrete deck and proof of

concept testing for the underside of the deck was conducted for surface and subsurface evaluation. 3-D

photogrammetry was combined with passive thermography to detect spalls, cracks and delaminations

for the top of the concrete bridge deck, while active thermography was investigated for bottom deck

surface condition assessment. Successful field demonstrations validated results comparable to MDOT

inspections. Recommendations for immediate implementation for condition assessment of the top of a

concrete deck are included for introducing the BridgeViewer Remote Camera System into current

bridge inspections to provide a photo inventory of the bridge deck captured at 45mph and above using

GoPro cameras. The combined optical photogrammetry (3DOBS) and passive thermography

technologies provide an objective analysis of spalls, cracks and suspected delaminations while

traveling at near highways speed. Using the same 3DOBS technology with higher resolution cameras

and slower speeds, cracks can be detected as small as 1/32 in. Laboratory and field demonstrations

show active thermography would benefit from further development as a remote sensing technology for

condition assessment on the underside of the bridge deck.
