Development of a Concrete Bridge Deck Preservation Guide

项目名称：	Development of a Concrete Bridge Deck Preservation Guide
摘要：	Successful bridge deck management requires 1) accurate condition assessment and 2) application of the right treatment to the right deck at the right time. Condition assessment can be performed using numerous tools and techniques, but some are more effective than others, depending on the deck condition. Similarly, while many treatments are available, their ability to extend deck service life depends on the condition of the deck at the time of application. A synthesis of best practices for both condition assessment and treatment selection would be useful to Utah Department of Transportation (UDOT) bridge engineers responsible for managing the bridge network in Utah. At the present time, many bridge engineers and inspectors rely heavily on visual inspection. While visual inspection can provide valuable information for many bridge decks, the presence of stay-in-place forms and/or deck surface treatments such as asphalt overlays can greatly limit an inspector�s ability to accurately determine deck condition. Furthermore, visual inspection alone cannot be used to track changes in concrete bridge deck properties until damage is manifest, at which time the deck is no longer a good candidate for the application of cost-effective preventive maintenance treatments.
