This research project aims to quantify the performance levels of surface repairs implemented on the Champlain Bridge elements after several years of service. Concrete surface repairs are applied to restore concrete elements affected by rebar corrosion, cracking and chipping by freeze-thaw cycles and de-icing salts.
This project will provide JCCBI with recommendations on appropriate materials and processing techniques to ensure effective and durable surface repairs.
