This report documents observations on the performance of six representative coating systems applied to a steel railroad bridge in 1994 as part of an Army Corps of Engineers field study. The objective of the study was to compare the performance of industry-accepted coating systems as applied to steel surfaces cleaned and prepared according to four different industry standards. The coatings were applied under contract by a local sandblasting and painting company working under typical field conditions. Two field inspections of the coatings were conducted - once after 1 year of service and again after 5 years of service. This report provides details on surface preparation, coating application, and field performance, including photographs of the test structure and manufacturers' literature on the six coatings tested. |
