Applications of Precast Concrete in Repair and Replacement of Civil Works Structures

The objective of this study was to develop, review, and analyze selected case histories involving applications of precast concrete in the repair or replacement of civil works structures. Information was obtained through literature searches; discussions with designers, precasters, and contractors; visits to project sites; and discussions with project personnel. Each case history includes a description of the project, the cause and extent of the deficiency that necessitated repair or replacement, design details, descriptions of materials and precasting procedures, construction techniques, costs, and performance to date of the precast concrete. Based on a review and analysis of these case histories, recommendations for future applications of precast concrete were developed, and areas that could benefit from research were identified. (MM).
