Precast Prestressed Concrete Bridge Deck Panels

Pdf Summary

The special report presents guidelines for the design, manufacture, and erection of precast prestressed concrete bridge deck panels. These guidelines are based on research and practical experience gained from their use in various parts of the United States. The report includes a brief history of bridge deck panels, suggestions for dimensioning and detailing of panels, techniques for casting panels, and ideas for handling, shipping, and erection of panels. An appendix section provides a fully worked design example of a bridge deck panel meeting AASHTO specifications. Additionally, the report includes pictorial examples of bridge deck panel applications.<br /><br />Precast prestressed concrete deck panels are widely used in bridge construction in the United States. They are used as a composite part of the completed deck, replacing the main bottom transverse deck reinforcement and serving as a form surface for the cast-in-place concrete upper layer. The panels have proven to be economical and convenient, reducing the need for installing and removing timber forms when casting a full-depth deck. The report emphasizes the importance of proper design, detailing, and installation for high-quality decks with good durability.<br /><br />The design example in the appendix shows the configuration and reinforcement of a panel, including stress calculations and the number of strands required for prestressing. The report also showcases various applications of precast prestressed concrete panels on different bridge structures. These applications demonstrate the versatility and effectiveness of using deck panels in bridge construction. Overall, the report serves as a valuable resource for engineers and construction professionals involved in bridge deck panel design and installation.
