• Abstract:
  Direct coastal exposure imposes serious problems to structural and reinforcing steel in bridges. Corrosion causes expansion of the steel resulting in a variety of problems including spalling of reinforced concrete. This problem can become especially severe under the deck where salt-laden moisture condenses and is not washed away by the rain. ; The Yaquina Bay Bridge in Newport, Oregon suffered from severe corrosion problems making it necessary to replace the deck and sidewalk sections throughout the three steel arch spans. With the new deck in place, the tops of the steel deck stringers are inaccessible for sand-blasting and painting and are thus subject to corrosion. The purpose of this experimental features study was to determine the effectiveness and suitability of the Chevron Industrial Membrane (CIM) for providing permanent corrosion protection on the tops of steel deck stringers and other similar members in conjunction with the deck replacement project on this structure.
