Specially Constructed Bridges: Activities for Fiscal Year 1983

摘要

The field performance of bridge features including masonry coatings, galvanized steel, weathering steel, conventional deck reinforcing steel, and epoxy-coated reinforcing steel were examined either visually or nondestructively on various pre-selected bridges throughout Kentucky. Additionally, a nationwide survey of state highway authorities was conducted on the application and service performance of stay-in-place forms. All of the bridge features inspected appeared to be performing satisfactorily, except for the masonry coating failure on the I-471 twin bridges over the Ohio River at Newport. Results of the stay-in-place form survey support their application as a cost-saving feature.
