Abstract:

Thermal spraying, or metallizing, is a well-established method of corrosion protection. It is seldom used on bridges, though, due to higher initial costs than conventional painting. The Connecticut Department of Transportation (ConnDOT), however, metallized sections of four bridges between 1987 and 1990 as part of a Federal Highway Administration (FHWA) research project. Favorable results from that project prompted ConnDOT to specify metallizing for an upcoming bridge coating project that includes all structural steel of five local road bridges over the Connecticut Turnpike. This article discusses ConnDOT's decision to use field-applied metallizing on its bridge project. The technical aspects of the metallizing process, the service life of metallized coatings, and appropriate applications for the coatings are explained and discussed. Further, installation costs are projected for the current project and compared to the earlier FHWA-sponsored project. The article identifies situations that favor the use of metallizing over other bridge maintenance options.
