PCI eLearning Course T215: Design and Detailing of Full-Depth Precast Concrete Deck Panels-Precast Prestressed Concrete Bridge Deck Panels

Precast Prestressed Concrete Bridge Deck Panels

Pdf Summary

The special report provides guidelines for the design, manufacture, and erection of precast prestressed concrete bridge deck panels. The report includes a brief history of bridge deck panels and suggestions for dimensioning, detailing, casting, handling, shipping, and erecting the panels. The design example in the appendix demonstrates how to design a bridge deck panel meeting AASHTO specifications. The report also includes various pictorial examples of bridge deck panel applications. <br /><br />The use of precast prestressed concrete deck panels in bridge construction is widely adopted in the United States due to its economic and convenient nature. The panels are used as a composite part of the deck, replacing the bottom transverse reinforcement and providing a form surface for the cast-in-place concrete upper layer. The report highlights the importance of proper detailing, such as the dimensioning and type of reinforcement, in ensuring the performance and durability of the panels.<br /><br />The report also addresses concerns related to cracking in bridge deck panels, specifically reflective cracking in the cast-in-place concrete slab. The cracking is often limited to the surface and does not impact the structural integrity of the bridge. The report emphasizes the need for proper grouting and concrete bearing to prevent cracking related to nonrigid bearing of the panels on the longitudinal beams.<br /><br />Overall, the report concludes that precast prestressed concrete bridge deck panels offer an economical and efficient deck system. It recommends following the guidelines and design practices presented in the report to ensure high-quality and durable bridge decks.
