Innovative Cold Spray Technique Aims to Revitalize Aging Bridges

July 16, 2025 - 10:12

Researchers from UMass and MIT are pioneering a novel cold spray technique designed to extend the lifespan of aging bridges across the United States. As many of the nation’s infrastructure components continue to deteriorate, this innovative method offers a promising solution to restore structural integrity without the need for extensive repairs or complete replacements.

The cold spray process involves propelling metal powders at high velocities onto the surfaces of bridges, effectively bonding them to the existing materials. This technique not only enhances the durability of the structures but also minimizes the downtime typically associated with traditional repair methods. By applying this technology, engineers hope to address the pressing issue of bridge maintenance while also ensuring public safety.

The collaboration between UMass and MIT underscores the importance of integrating advanced technology into infrastructure management. As the pilot tests progress, the potential for widespread application could lead to significant improvements in the longevity and reliability of essential transportation networks across the country.
