Bridge Maintenance To Enhance Corrosion Resistance And Performance Of Steel Girder Bridges, Luis M. Moran Yanez
Open Access Dissertations
The integrity and efficiency of any national highway system relies on the condition of the various components. Bridges are fundamental elements of a highway system, representing an important investment and a strategic link that facilitates the transport of persons and goods. The cost to rehabilitate or replace a highway bridge represents an important expenditure to the owner, who needs to evaluate the correct time to assume that cost. Among the several factors that affect the condition of steel highway bridges, corrosion is identified as the main problem. In the USA corrosion is the primary cause of structurally deficient steel bridges. …

The Long-Term Performance Of Concrete Crack And Deck Surface Sealers, Emily A. Byl
Open Access Theses
Concrete bridge decks in the State of Indiana are undergoing continuous deterioration and loss of service life due to the use of deicing salts during winter weather conditions. As salt water penetrates the deck through cracks and the concrete surface, chlorides, water and oxygen are able to access the reinforcement to initiate corrosion. The corrosion of reinforcing steel over time creates an ongoing need for costly deck repairs and/or deck replacement. This study investigates the performance of crack sealers and deck surface sealers as a potentially cost-effective method of increasing bridge deck service life. An experimental program was developed and …
