EVALUATION OF PACZYME AS A STABILIZING AGENT FOR UNPAVED SECONDARY ROADS

A STUDY WAS CONDUCTED TO EVALUATE THE EFFECTIVENESS OF PACZYME, A COMMERCIALLY MANUFACTURED AND MARKETED CHEMICAL ENZYME MATERIAL, IN STABILIZING THE SURFACE AND SUBGRADE OF UNPAVED, SECONDARY ROADS. FIVE TEST SECTIONS WERE SELECTED ON FOUR PROBLEM ROADS THAT WARRANTED STABILIZATION BECAUSE OF PHYSICAL CHARACTERISTICS OR THE EFFECTS OF ADVERSE WEATHER CONDITIONS. THESE ROADS INCLUDED BOTH SILTY SOIL AND CLAY SOIL TYPES. TEST SECTIONS WERE PREPARED ACCORDING TO RECOMMENDATIONS OF THE PACZYME DISTRIBUTOR AND/OR THE MANUFACTURERS' REPRESENTATIVE. AFTER OBSERVING THESE SECTIONS OVER A SEVEN TO NINE MONTH PERIOD, IT WAS CONCLUDED THAT PACZYME STABILIZATION IS OF NO APPARENT BENEFIT. /AUTHOR/
