Precast Repair of CRC Pavements

This report presents a summary of the results of an investigation into the design, fabrication and installation of precast concrete panels for the repair of continuously reinforced concrete (CRC) pavements. Factors affecting the design of precast panels for CRC repairs are presented. Problems associated with transporting and placing the panels are discussed. Two field installations using the method are presented and illustrated. Conclusions presented include: (1) The use of precast panels for the repair of CRC pavements is a viable alternative; (2) repairs can be made with less than a 6 hr lane closure time; and (3) the method is cost effective when user delay costs are included.
