Full-Span Precasting for Light-Rail Transit and High-Speed Railway Bridges

In this article, the author assesses the organization of full-span precasting facilities for light-rail transit and high-speed railway prestressed concrete bridges. Full-span precasting is a rapid construction method that is repetitive and offers high-quality casting and year-round erection. Among the topics covered in this article are the loading, kinematics, support and launch systems, performance, productivity and structure-equipment interactions for equipment used in the transport and placement of full-span precast concrete beams.
