Deconstruction of the original Champlain Bridge

Critical Analysis and Performance Monitoring of Surface Repairs of Concrete Elements

• Research Center: Sherbrooke University and Laval University, Faculty of Engineering and Department of Civil Engineering and Water Management
• Researchers: Richard Gagné Eng. and Benoit Bissonnette Eng.

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.

Objectives

• Measure the performance of surface repairs in terms of adhesion, cracking, durability
• Study the parameters influencing the long-term durability of repair methods and assess their expected lifespan
• Recommend an optimized surface repair approach based on specific needs
