Home About Us Practice Areas Technologies Careers News Contact Us 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.

Home About Us Practice Areas Technologies Careers News Contact Us Impact Echo Impact Echo Investigation are performed to assess the condition of slabs, beams, columns, walls, pavements, runways, tunnels, and dams. Voids, honeycomb, cracks, delaminations and other damage in concrete, wood, stone, and masonry materials can be found utilizing the Impact Echo(IE) method. IE investigations are also performed to predict the strength of early age concrete if the member thickness is known and to measure the thickness of structural members. An advantage of the Impact Echo as opposed to the Ultrasonic Pulse Velocity(UPV) method is that only one side of the structure needs to be accessible for testing. In addition, the IE method will provide information on the depth of a flaw or defect, in addition to mapping its lateral location and extent. Copyright © 2019 AID. All rights reserved.
