Abstract:This study was initiated to provide review of common bridges to determine the performance of their components. Seven bridge types were selected that constituted 85 % of the Kentucky Transportation Cabinet (KYTC) bridge inventory. 319 bridges were inspected by Kentucky Transportation Cabinet (KTC) researchers, representing 5 about % of those bridges. Common details/components were identified and evaluated including features of interest to the KYTC Study Advisory Committee. In addition to those findings, KTC researchers evaluated KYTC National Bridge Inventory reports and maintenance needs forms for the same bridges.
Design modifications/material changes were recommended to improve performance of new bridges. Additionally, remedial measures were identified that would enhance the durability of existing bridges. Recommendations were also provided that would permit a more proactive approach to bridge maintenance activities.
