DETRIMENTAL EFFECTS OF NATURAL SOIL AND WATER ELEMENTS ON DRAINAGE PIPE STRUCTURES IN ALABAMA

FIELD STUDIES WERE CONDUCTED IN ALABAMA ON SOIL AND WATER PARAMETERS TO DETERMINE THEIR RELATIONSHIP TO CULVERT PIPE CORROSION. THE TYPES OF CULVERT MATERIALS INVESTIGATED INCLUDED CONCRETE, GALVANIZED STEEL, BITUMINOUS-COATED GALVANIZED STEEL, ALUMINUM, BITUMINOUS-COATED ALUMINUM, PITCH-IMPREGNATED FIBER, CAST IRON, AND VITRIFIED CLAY. WATER PARAMETERS MEASURED INCLUDED PH, OXIDATION-REDUCTION POTENTIAL, DISSOLVED OXYGEN, AND RESISTIVITY. SOIL PARAMETERS DETERMINED WERE PH, OXIDATION-REDUCTION POTENTIAL, RESISTIVITY, AND GEOLOGIC CONDITIONS. SOIL PARAMETERS GENERALLY WERE LESS SIGNIFICANT THAN WATER PARAMETERS IN THE CORROSION OF CULVERTS. A GRAPHICAL METHOD BASED ON PH, RESISTIVITY, AND DISSOLVED-OXYGEN CONTENT OF WATER WAS DEVISED FOR ESTIMATING LIFE EXPECTANCY OF STEEL PIPE. GALVANIZED PIPE IS NOT RECOMMENDED FOR USE IN AREAS HAVING RUNOFF WATER OF LOW RESISTIVITY, LOW PH, OR HIGH DISSOLVED-OXYGEN CONTENT UNLESS IT IS EFFECTIVELY COATED WITH BITUMINOUS MATERIAL. ALUMINUM PIPE WAS FOUND TO BE LESS AFFECTED BY ACIDIC WATERS THAN GALVANIZED STEEL, BUT LESS RESISTANT TO ABRASION EFFECTS. CONCRETE PIPE WAS HIGHLY RESISTANT TO CORROSION EXCEPT IN AREAS AFFECTED BY ACID MINE DRAINAGE. PITCH-FIBER PIPE PERFORMED WELL EXCEPT FOR SEPARATION OF THE LAMINATE IN THE INVERT OF THE UP-GRADIENT END. CAST IRON AND VITRIFIED CLAY PIPE ARE NOT COMMONLY USED AS CULVERT MATERIAL IN ALABAMA, BUT THEY SHOULD BE CONSIDER- ED FOR USE IN VERY ACIDIC AREAS OR OTHER SPECIAL PROBLEM AREAS. RECOMMENDATIONS FOR USE OF PARTICULAR TYPES OF DRAINAGE STRUCTURE MATERIALS IN CERTAIN AREAS OF THE STATE ARE MADE ON THE BASIS OF WATER AND SOIL FACTORS. /AUTHOR/
