PCI eLearning Course T220: Production and Construction Details of Full-Depth Precast Concrete Deck Panels-Bridge Deck Report

Bridge Deck Report - Production

Pdf Summary

This report discusses various wearing and protection systems for precast concrete bridge deck panels. The report highlights five common types of systems: low permeability concrete panels, monolithic sacrificial concrete overlays, thin bonded polymer concrete overlays, thin bonded concrete overlays, and waterproof membrane overlays with asphalt. Each system is described in detail, including their construction steps, costs, and performance. The low permeability concrete panels are recommended as the most practical and economical option, providing a smooth riding surface and enhanced protection against the intrusion of chlorides. The monolithic sacrificial concrete overlays are also a good option, providing long-lasting protection and allowing for surface grinding when necessary. On the other hand, the thin bonded polymer concrete overlays, thin bonded concrete overlays, and waterproof membrane overlays with asphalt are more expensive and may require future maintenance and replacement. The report also discusses the importance of proper surface preparation and profile grinding for a successful overlay system. Overall, the report suggests that the choice of wearing and protection system should be based on factors such as cost, durability, and ride quality, and should be evaluated on a case-by-case basis.
