Abstract:
During the latter part of 1988, a short term research study was initiated to evaluate the performance of selected corrugated metal crossroad pipe (CMP) installed since 1974. Conflicting earlier reports on CMP performance created sufficient doubt that a followup study was initiated in 1989. The data in the report support the decision to prohibit the use of CMP for all crossroad installations in Districts 1, 2, 4, and 5 except for limited situations, and to consider the use of CMP in Districts 3 and 6 on a site specific basis.
