Abstract:
Precast concrete pavements (PCPs) have been shown to be promising alternatives for repair and rehabilitation of the aging highway infrastructure in the United States. The article presents details on technical considerations related to design, fabrication, and installation of PCPs, especially concrete requirements, joint spacing, support conditions, load transfer at joints, panel reinforcement and prestressing, and panel production and installation rates.
