This document reviews the use of precast concrete panels for improving pavements. It discusses several precast panel systems that have been used internationally and in India, including precast prestressed concrete pavement systems, the Kwik slab system, the Michigan method, the Roman Road system, the Uretek method, and the Fort Miller super slab system. The review found that precast panels allow for controlled, off-site fabrication and rapid construction or repair of pavements. However, their use has been limited in flexible pavements. Available analysis and design methods can be adapted to improve different pavement types using precast panels.
