A new parapet wall was constructed on the existing bridge deck using GFRP V-Rod reinforcement. The design was completed following current codes and design standards outlined in the ACI 318, ACI 440, and Canadian Highway Bridge Design Code (CHBDC). The design was supported by lab and field pull- out tests. It was determined that the use of GFRP provided the Region with the best reinforcement solution considering long-term sustainable benefits and non- corrosive properties of GFRP. The durability of GFRP was the driving factor in using GFRP reinforcement. The actual costing also proved to be very favorable in comparison with conventional epoxy-coated reinforcement. The region of Niagara has accepted the design and use of GFRP in certain components of bridge structures, with consideration for future use in other bridge structures.
