DRAINAGE PIPE STUDY

THE PRIMARY OBJECTIVE WAS TO DETERMINE ESTIMATED LIFE EXPECTANCIES OF SEVERAL TYPES OF DRAINAGE PIPE SUBMERGED IN VARIOUS TYPES OF SOIL FOUND IN LOUISIANA. A CORRELATION WAS THEN ATTEMPTED BETWEEN THE STUDY RESULTS AND THOSE OF CALIFORNIA'S "METHOD OF ESTIMATING SERVICE LIFE OF METAL CULVERTS," TEST METHOD NO. CALIFORNIA 643-B, 1963. THE FINDINGS SHOW THAT THE CALIFORNIA METHOD IS APPLICABLE TO CONDITIONS FOUND IN LOUISIANA. THUS, BY EVALUATION OF SOIL CHARACTERISTICS IN THE LABORATORY, THE EXPECTED LIFE OF METAL PIPE CAN BE PREDICTED. THE LIFE OF A METAL PIPE CAN BE EXTENDED BY USE OF A ZINC COATING AND BY USE OF AN ASPHALT COATING. THE ASPHALT COATING ADDS AN ESTIMATED 8 YEARS TO THE LIFE OF THE PIPE. TABLES WERE PREPARED SHOWING THE RELATIONSHIP BETWEEN ESTIMATED LIFE AND VARIOUS SOIL CONDITIONS. THESE TABLES ARE ARRANGED ON A DISTRICT BASIS SO THAT EACH DISTRICT WILL BE ABLE TO READILY DETERMINE THE APPROPRIATE TYPE OF PIPE FOR THE EXISTING SOIL CONDITION. /AUTHOR/
