EVALUATION OF DRAINAGE PIPE BY FIELD EXPERIMENTATION AND SUPPLEMENTAL LABORATORY EXPERIMENTATION

This study investigates the durability of metal drainage pipe in Louisiana, where durability of such pipe is as important as strength because of harsh environs which promote corrosion. Since 1973, eleven types of galvanized steel and aluminum test culverts have been installed at test sites. The test sites were based on geographical location and on the pH and electrical resistivity values of the soil and effluent. This interim report relates field and laboratory observations concerning the condition of the test pipes after four years of in-service exposure. It was found that the asbestos-bonded, asphalt-coated, galvanized steel pipe was performing better than the other ten types of culverts in resisting corrosion. All of the coatings on the various test culverts are showing signs of distress at the highly corrosive test sites.
