GPR is ideal as an NDT survey and investigation method for the investigation of bridge structures. It can be used to map reinforcement detail, locate post-tensioned tendons, determine general construction detail, thickness of construction and much more...
The purpose of the investigation was to determine the reinforcement details (concrete cover, bar type and diameter and bar arrangement, spacing and cover) within the elements of the bridge including the road deck, main arch beams, transverse beams and longitudinal beams
Survey, testing and investigation methods included:
The reinforcement details of the bridge for all elements surveyed was successfully determined.
The main advantages of using GPR rather than more traditional methods such as Cover Meter or Ferroscan are:
