Precast Bridge Deck Design Systems

Pdf Summary

Precast concrete is increasingly popular for building and rehabilitating bridges due to its durability, construction speed, and reduced need for maintenance. The largest precast elements used in bridges are prestressed box girder segments, allowing for spans up to 800 ft. AASHTO-PCI standard I girder sections are also commonly used. Precast elements are also used for bridge deck rehabilitation, offering rapid construction and minimized traffic interference. Precast concrete is cost-effective and provides greater durability compared to cast-in-place concrete. The use of precast concrete has been successful for various types of bridge superstructures. Research is ongoing to improve the structural systems and materials used in precast decks, which are expected to continue being used in future bridge construction and rehabilitation projects.
