Samenvatting
Four delaminated bridges were epoxy injected and compared with bridges that were not injected. The injection history, cores, and condition reports for the bridges demonstrated that a plane of delamination, once repaired, stayed repaired, and that the surface of the deck remained intact with a frequency of injection of once every 4 years. Continued observation for 7 years after the last injection of the decks validated that delamination can be effectively repaired and can remain serviceable up to approximately 4 years, when additional injections or another type of repair can be scheduled. The use of timely epoxy repair for a bridge undergoing untimely delamination extends the useful life of the original deck.
