PROMISING MATERIALS AND METHODS FOR EROSION CONTROL

THE MAIN OBJECTIVES WERE TO DEVISE A SYSTEM OF METHODICAL EROSION CONTROL ON AIR FORCE INSTALLATIONS AND TO FORMULATE ACCEPTANCE SPECIFICATIONS BASED ON STANDARDIZED TESTING PROCEDURES FOR MATERIALS TO BE USED WITH THE SYSTEM. EROSION ON AND AROUND AIR FIELDS IS CREATED NOT ONLY BY WIND AND WATER BUT ALSO BY MANY OTHER FORCES SUCH AS DOWNDRAFT FROM AIRCRAFT (WHICH IS CONSIDERABLY MORE SEVERE THAN NATURAL WINDS), VEHICULAR TRAFFIC, FUEL SPILLAGE, AND OTHER MAN-MADE CAUSES. THE MAIN EMPHASIS WAS ON PREVENTION OF EROSION RATHER THAN A COSMETIC TREATMENT OF DAMAGE CUASED. IN REALIZATION OF THE FACT THAT NO SINGLE PRODUCT OR TREATMENT CAN SERVE ALL PURPOSES OF EROSION CONTROL BUT THAT, ON THE OTHER HAND, LOGISTICS REQUIRES A SIMPLE PROCEDURE AND A MINIMUM OF DIFFERENT MATERIALS, AN EFFORT WAS MADE TO FIND PRODUCTS THAT, EVEN IF USED FOR DIFFERENT EFFECTS, COULD BE APPLIED IN THE SAME MANNER, EITHER BY THEMSELVES OR IN COMBINATION. ANOTHER OBJECTIVE WAS TO TREAT THE EXISTING SOILS AS INTEGRAL PARTS OF THE EROSION-RESISTANT SURFACE RATHER THAN TO COVER THE SOILS BY A PROTECTIVE COATING. IN OTHER WORDS, SOIL MODIFICATION WAS THE OBJECTIVE RATHER THAN A "BAND-AID" APPROACH TO DAMAGED SOILS. THE PRODUCTS FOUND TO SATISFY THESE REQUIREMENTS ARE EMULSIONS THAT HAVE CHARACTERISTICS SUCH AS A SIMILARITY OF EMULSIFICATION SYSTEMS AND COMMON INGREDIENTS THAT MAKE THEM MUTUALLY COMPATIBLE. THE MAIN DIFFERENCE BETWEEN THE PRODUCTS IS THAT THEY WERE DEVELOPED TO BE COMBINED WITH SPECIFIC FORMS OF SOILS, I.E., ROCK, GRAVEL, SAND OR FINE PARTICLES IN LOOSE FORM OR EMBEDDED IN ARTIFICIAL SURFACES SUCH AS PAVEMENTS. THE PAPER DESCRIBES PROPERTIES, APPLICATIONS, FIELD EXPERIENCE, AND TENTATIVE SPECIFICATIONS AND TESTING PROCEDURES DEVISED FOR AIR FORCE USE. DATA, PHOTOGRAPHS, AND CASE HISTORIES ARE PRESENTED TO ILLUSTRATE THAT THE PRODUCTS SELECTED CONSTITUTE VERY PROMISING MATERIALS FOR FORTIFYING EARTH SURFACES AGAINST THE WIDEST VARIETY OF FORMS OF EROSION. /AUTHOR/
