Observation, Documentation, and Performance Evaluation of Bridge Deck using Multi-Crystalline Intermixed Concrete Enhancer and Surface Sealer
Water intrusion on bridge decks leads to degradation of the concrete and reinforcement at an accelerated rate when compared to other concrete bridge components. As an example, freeze/thaw effects can result in delamination or spalling, and chloride ion penetration can result in the material degradation of the concrete and steel reinforcement. Eliminating or reducing water intrusion into the bridge deck concrete has the potential to greatly increase the service life of the bridge deck and, subsequently, the overall bridge. An admixture product and surface sealer are proposed for use on a bridge construction project in Appanoose County, Iowa. The bridge superstructure will consist of concrete prestressed, precast girders topped by a concrete, steel-reinforced deck. The project presents an opportunity to observe and document the construction and performance of the deck with the inclusion of the moisture prevention products.
