Bridge Management with GPR

Ground penetrating radar (GPR) is regularly applied to examine bridge deck, roads,railways and runways. Many applications have been pioneering proof-of-concept tests to define the benefits and limitations of GPR. For the quality of bridge major include three parts: the thickness of the liner; the Defects of the liner such as the voids, non-compacting area and crack; the number diameter of the rebar concrete deterioration (delamination and debounding) and rebar corrosion. There are many situations where GPR signals do contain quantitative information useful for developing data needed for engineering decision making.
