Polyurethane Foam Infill for Fiber-Reinforced Polymer (FRP) Bridge Deck Panels

The objective of the research was to develop, test, and evaluate fiber-reinforced, polyurethane (PU) foams to replace the costly honeycomb construction currently used to manufacture FRP bridge deck panels. Initially, the effort focused on developing an FRP sandwich panel to replace the precast, stay-in-place forms currently used to construct reinforced concrete bridge decks. However, during the course of the project, the research effort expanded to include full-depth bridge deck panels as well. This report documents the results of this study.
