PCI eLearning Course T215: Design and Detailing of Full-Depth Precast Concrete Deck Panels-Field Performance of Full Depth Precast Panels in Bridge Deck Reconstruction

Field Performance of Full Depth Precast Panels in Bridge Deck Reconstruction

Pdf Summary

The study evaluates the use of precast concrete panels for bridge deck replacement. While they have been successful, there are issues with joint performance, leakage, and overlay cracking. Post-tensioning in the longitudinal direction and proper joint configuration improve performance. Various overlays are discussed, with silica fume being more cost-effective than latex modified concrete. Attention to design and construction details is crucial for successful implementation. Precast panels are a reliable solution for bridge deck replacement, with regular maintenance necessary for longevity.
