ENCASEMENT OF PIPELINES THROUGH HIGHWAY ROADBEDS: SYNOPSIS OF FINAL REPORT FOR NCHRP PROJECT 20-7, TASK 22

Warrants for providing increased protection to pipelines crossing highways are discussed. The practice of using casing pipes to protect crossing pipelines is examined. Problems encountered with this practice, particularly related to interference with induced-current cathodic protection systems for pipelines, are presented. Two failures of pipelines, which the National Transportation Safety Board attributed to the use of casings, are documented. Results of a survey of state transportation departments, railroads, trade associations, utility companies, and pipeline operators are included.
