Evaluation of Precast Patches on U.S. 60 Near the New Kent and James City County Line

Report No: 06-R22

Published in 2006

About the report:

This project evaluated the use of precast concrete patches for repairing jointed concrete pavement. Six patches were placed: three had dowels cast into them during fabrication, and three had dowels inserted in place (dowel bar retrofit). Fabrication and placement were documented. The load transfer efficiency at the joints and the ride quality were determined approximately 2 weeks after construction. After 1.5 years, the general condition of the patches was determined by a visual survey for cracks and spalls. In general, there were no distresses on the replaced slabs except for a few hairline cracks; however, there were failures in the joint area, mainly because of dowels, that were attributed to poor construction practices.
