Grouting Concrete Reinforcing Steel: Review of WSDOT's Specifications and Proposed Modifications

Improving the conditions of existing bridges often requires the addition of new portions to the in-place structures. This may be done by drilling and grouting reinforcing bars to join the new portion to the existing structure. Recently, fast-curing resins have been developed that expedite the grouting of reinforcing bars. On the other hand, epoxy-coated bars are specified in certain bridge components to prevent bars' corrosion. Resin grouting of epoxy-coated bars has cast doubt on the bond of the resin grout to the epoxy coating. This report is a brief summary of volume one of Bending/Straightening and Grouting Concrete Reinforcing Steel: Review of WSDOT's Specifications and Proposed Modifications.
