摘要
As transportation officials continue to focus on improving safety and reducing maintenance by producing fast, durable structures, the use of prestressed/precast concrete for the nation's bridges continues to grow - the material is employed in more than 50 percent of all bridges built each year. New technology is allowing increased spans, along with durability, design flexibility, aesthetics and myriad other advantages.
