Bridge Deck Evaluation

AID has completed inspection and deterioration evaluation of more than two hundred (200) bridge decks/concrete structures, in the New York – New Jersey metropolitan area and Pennsylvania.

AID routinely performs deck and substructure evaluations using Ground Penetrating Radar (GPR), a non-destructive testing tool as well as other nondestructive technologies and traditional methods, to review existing conditions of bridge decks. GPR has been used by many transportation authorities, including NJDOT, for bridge and pavement condition assessment. GPR technology is typically applied to estimate the locations of the deterioration of the top of the rebar mat of concrete bridge decks, to evaluate the thickness of the concrete cover above the top reinforcement mesh and also determine the thickness of asphalt overlay on bridge decks that are overlaid by asphalt. The above information can be used to estimate the repair location for each bridge deck. AID is capable of conducting dual air-launched and ground-coupled surveys utilizing 2 GHZ air-launched or 1.5 GHz ground coupled antennas.
