Evaluation of Drainage Pipe By Field Experimentation and Supplemental Laboratory Experimentation. Final Report July 1972-November 1984

摘要

The study represents an investigation of the durability properties of coated and uncoated, corrugated, galvanized steel and aluminum drainage pipe in Louisiana. The highly corrosive environments in some areas of the state make durability requirements of metal pipe as critical as strength requirements. Department personnel installed ten types of metal drainage pipes at each of ten locations in 1973. An eleventh type of drainage pipe was added to each location for evaluation in 1975. In 1977 the investigators installed the battery of test culverts at another test site where the environment differed from that of the previous ten locations. In 1979 additional pipe types were added to several of the test sites. The test sites were selected based on geographical location and on the pH and electrical resistivity of the soil and effluent.
