Post-Installed Adhesive-Bonded Splices in Bridge Decks
The purpose of this study was to investigate the feasibility of using post-installed adhesive-bonded splices for bridge deck additions. Current bridge deck additions involve the removal of part of the existing bridge deck so that reinforcing bars for the new deck can be spliced with those in the existing deck. The alternative presented is to drill into the side of the existing deck and install reinforcing bars using a structural adhesive. The study includes both constructability concerns and structural requirements for the splices. The specific objectives were to: examine the methods used to install adhesive splices and determine if the methods are practical for use on a job site; perform flexural tests to determine the splice length required to achieve full flexural strength when using an adhesive-bonded splice; perform shear tests to determine the shear strength of adhesive-bonded dowel bars; provide design recommendations for splice lengths for adhesive-bonded reinforcement in bridge decks additions; and provide design recommendations for determining the shear strength of adhesive-bonded dowel bars in bridge deck additions.
