摘要

The report documents the repair of five locations along the I-65 Expressway in Jefferson County. KY. The repair involved: (1) the precast prestressed concrete girder spans between Jacob Street and Gray Street, (2) the reinforced concrete bearing pads of Bridge Pier 4 at the intersection of Jefferson Street and Preston Street, (3) the reinforced concrete bearing pads of Bridge Pier 6 near the intersection of Main Street and Hancock Street, (4) the precast prestressed concrete girder spans between Chestnut Street and Gray Street, and (5) the reinforced concrete pier column on East Muhammad Ali Blvd. The precast prestressed concrete girders were wrapped with carbon fiber reinforced polymer (CFRP) fabrics at the cracked locations to prevent or limit excessive translations in both vertical and horizontal directions.
