Abstract:

Metallizing is evolving as a versatile coating solution for steel bridge elements and has seen increased recognition by multiple transportation agencies, including the U.S. Federal Highway Administration (FHWA) and the Canadian ministère des Transports du Québec. Metalizing is a term commonly used to describe the practice of thermally spraying molten zinc, aluminium or zinc/aluminium alloy on surfaces of exposed steel elements to provide both physical barrier and effective sacrificial protection through galvanic action. In order to derive the maximum benefits of metallizing, bridge designers need to know the slip resistance of metallized faying surfaces required to develop slip-critical connections in the bridge structure. This helps to eliminate the current labor-intensive and time-consuming practice of masking off all connection faying surfaces to preserve their conditions prepared in accordance to prevailing design standards. Therefore, the ability to design for and supply coated faying surfaces is an important option, and achieving a reliable slip resistance is an essential variable in this option. This presentation will discuss results of both short and long-term studies performed to characterize the slip resistance of metallized faying surfaces used with high-strength bolted slip-critical connections in bridges.
