Concrete Patching Methods

Many bridge decks and substructures on Kentucky Transportation Cabinet (KYTC)-managed structures are in dire need of rehabilitation. But a lot of the methods used to patch concrete result in poor performance, with failures in the new patching material and/or adjacent existing materials occurring not long after patches are completed. When failures happen, KYTC has to replace structural components, which comes at a greater cost. As such, the Cabinet needs guidance on materials and methods it can use to install concrete patches that are not vulnerable to rapid failure.
