Description
A number of prestressed concrete box beams on the two]span KY 100 Bridge (107B00035N) have
severe cracking at the ends due to excessive shear, and/or torsion, and/or other causes. One span
of the bridge extends over the CSX Railroad while the other is over South Railroad Street. The bridge
is located in Simpson County, KY in KyDOH District 03. The objective of this study is to repair the
bridge using carbon fiber reinforced polymer (CFRP) composite fabric. The repair involves removal
of unsound concrete in the spalled regions, cleaning of the rusted steel bars, application of primer
and bonding agents, and application of concrete mortar. CFRP fabric and high strength resin will be
applied on the outside girders to strengthen them.
