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

Minnesota Department of Transportation (MnDOT) is interested in learning about effective practices and costs to structurally rehabilitate bridge-size large‐diameter (10 feet or greater) corrugated metal pipe (CMP). Of particular interest are current practices of other northern cold-weather states for extending the life of a deteriorating CMP by performing a repair or rehabilitation that provides continued structural support for traffic. Examples of such repairs are the use of epoxy or cementitious sprayed‐on liner, sliplining, or cured‐in‐place pipe. Any repair techniques found to be effective could be considered as alternatives to excavation and replacement of the deteriorating pipe. To support this effort, CTC & Associates conducted a survey of transportation agencies and a literature search to identify practices for repairing large-diameter CMP. This document includes a summary of findings from the email survey, related documents, the full text survey responses, and three of the related documents in the appendices.
