Large Corrugated Metal Pipe Repair Techniques: A Survey of Practice and Related Resources

Status:  Complete
Report Date:  12/31/2015


Much of the research-oriented literature on rehabilitation methods for corrugated metal pipe culverts is focused on smaller-diameter pipes. MnDOT is interested in learning more about the effective practices and costs to structurally rehabilitate bridge-size large‐diameter (10 feet or greater) CMP. Of particular interest are current practices for extending the life of a deteriorating CMP by performing a repair or rehabilitation that provides continued structural support for traffic. This Transportation Research Synthesis uses a literature review and a survey of cold-weather states to gather information about repair techniques, potential environmental concerns, structural issues to consider before and after repair, and the life-cycle cost-effectiveness of various repair techniques used for large-diameter CMP.
