Project Description: The unique "X-shape" bridge lacked sufficient top and bottom rebar due to a shop drawing error. Both positive and negative bending capacities needed to be increased at certain regions of the bridge slab.
Solution: The carbon-based Tyfo® SCH-41 Composite System was utilized on the bottom side of the slab to strengthen areas lacking positive moment reinforcement. For negative bending strengthening, the Tyfo® UC carbon plates were inserted into saw cuts on the topside of the slab. The Tyfo® S high-strength epoxy was filled into the saw cuts around the plates and fine gravel was adhered at the top surface.
Summary: The bridge slab was strengthened by creative, non-obtrusive methods with the Tyfo® Composite Systems.
