INVESTIGATION OF ENZYMATIC MATERIALS FOR SOIL STABILIZATION

A NEED EXISTS FOR SOIL-STABILIZING MATERIALS CAPABLE OF IMPROVING SOILS BY PROVIDING STRENGTH, WATERPROOFING, AND ALLEVIATION OF DUST IN SUPPORT OF MILITARY ROAD AND AIRFIELD OPERATIONS. LABORATORY AND FIELD INVESTIGATIONS WERE CONDUCTED ON TWO PROPRIETARY ENZYMATIC MATERIALS. LABORATORY TESTS SHOWED THAT NEITHER OF THE TWO ENZYMATIC PRODUCTS WAS CAPABLE OF SATISFYING REQUIREMENTS AS A DUST PALLIATIVE WHEN APPLIED AS A SURFACE-PENETRATION TREATMENT. SUBSEQUENT TESTS OF ONE OF THE PRODUCTS AS A SOIL-COMPACTION AID SHOWED NO BENEFITS TO A CLAYEY SILT WITH RESPECT TO DENSIFICATION, STRENGTH, WATER REQUIREMENTS FOR COMPACTION, WATER-RETENTION PROPERTIES, OR SOIL WATERPROOFING. TWO ROADWAY TEST SECTIONS, ONE UNTREATED FOR CONTROL AND ONE TREATED WITH ONE OF THE ENZYMATIC PRODUCTS, WERE CONSTRUCTED AND TRAFFICKED BY A MILITARY VEHICLE. MEASUREMENTS AND OBSERVATIONS MADE DURING CONSTRUCTION AND TRAFFIC TESTING SHOWED NO SIGNIFICANT DIFFERENCE BETWEEN THE TREATED AND UNTREATED SECTIONS WITH RESPECT TO STRENGTH BOTH AS-CONSTRUCTED AND THAT WHICH DEVELOPED WITH TIME, SURFACE ABRASION AND DUST GENERATION UNDER TRAFFIC ON DRY SURFACES, OR ABILITY TO SUPPORT TRAFFIC UNDER WET CONDITIONS. IT IS CONCLUDED THAT THESE ENZYMATIC MATERIALS HAVE NO POTENTIAL FOR MILITARY SOIL-STABILIZATION PURPOSES. /AUTHOR/
