Composite Action in Prestressed NU I-Girder Bridge Deck Systems Constructed with Bond Breakers to Facilitate Deck Removal
The Kansas Department of Transportation has released a report that investigates the influence of surface preparation, bond breakers, and interface reinforcement properties on horizontal shear transfer between precast and cast-in-place concrete surfaces. This project aims to facilitate in-situ removal of the bridge deck without damaging prestressed girders, and maintain composite action between the prestressed girder and reinforced concrete deck throughout the service-life of the structure.
