Abstract: Abstract: The Army has 1,500 vehicular bridges on its installations, with many experiencing high maintenance or replacement costs due to corrosion of the steel structure or of the reinforcing bar in the concrete deck. Under the Department of Defense Corrosion Prevention and Control Program (Project F12-AR15), a span of Bridge No. 4 at Fort Knox, Kentucky, was selected to demonstrate and validate a new corrosion-resistant hybrid composite bridge beam. The results of that project were published as ERDC/CERL TR-16-22 (September 2016). Bridge Diagnostics, Inc. (BDI) of Boulder, Colorado, was subcontracted to perform load testing and rating for the new bridge beam project to confirm that the replacement bridge span met its required load rating (HL-93) and performance criteria for deflection and strain. Results showed the bridge met all design specifications and load ratings.
