16 years of deployment of FRP material in bridges in Kentucky

A summary is presented on the deployment over the past fourteen years of high performance materials in a number of bridges in Kentucky. The field applications range from: (1) the “Clear Creek” bridge that was constructed in 1996 using two 610 mm (24 inch) deep hybrid glass/carbon I-girders; (2) a bridge deck in 1997 that is partially reinforced with glass FRP (GFRP) rebars; (3) a suspension bridge constructed in 1999 and having a 128 m (420 ft.) long GFRP superstructure; (4) a spread box prestressed concrete beam bridge constructed in 2001 and having a concrete deck reinforced entirely with 10 mm (3/8 inch) diameter carbon FRP rebars; (5) a three span prestressed concrete bridge retrofitted for shear using carbon FRP (CFRP) fabric in 2001; (6) a four span reinforced concrete bridge slab on girder retrofitted for flexure using CFRP laminates in 2004 ; (7) repair of reinforced concrete bridge pedestals using CFRP fabric in 2006; (8) a retrofit of the ends of prestressed concrete I-beams using CFRP fabric; (9) retrofit of two multi-span bridges using high strength steel wire fabric in 2007; (10) retrofit of bridge pier using 3-D CFRP fabric in 2010; (11) strengthening of a steel girder bridge using ultra high modulus CFRP laminates bonded to the steel girders in 2010. A discussion of the lessons learned along with recommendations is also presented.
