Patch Analysis of Reinforced Concrete Bridge Decks Using Ground Penetrating Radar
The common practice of patching decayed or damaged bridge decks introduces unique challenges to non-destructive testing (NDT) techniques when the deck is extensively patched. NDT techniques are useful to gain knowledge of damaged bridge decks, but it is important to know their limitations to correctly assess the condition and remaining life of the structure. Three bridge decks in the New England area were subjected to a suit of testing which included ground penetrating radar, half cell potential, chain drag/hammer sounding, visual inspection and core sampling. Two of the three decks had large patched areas. The data from each of the tests, specifically ground penetrating radar and half-cell potentials, allow for the comparison and the identification of the limitations of each individual test. Using the gained knowledge of the shortcomings of individual tests, it allows the data interpreter to identify ways to compensate for the unique difficulties caused by patched bridge decks. With a better understanding of the data collected from NDTs, higher precision quality control/quality assurance can be performed, which can lead to increased savings and higher durability of the bridge decks.
