SOIL EROSION, DUST CONTROL RESEARCH

THE ARIZONA HIGHWAY COMMISSION HAS AUTHORIZED A RESEARCH PROJECT BY THE UNIVERSITY OF ARIZONA ON SOIL EROSION AND DUST CONTROL. THE 18-MONTH PROJECT IS INTENDED TO SEARCH FOR, DETERMINE AND IDENTIFY STABILIZING AGENTS THAT ARE BEST CAPABLE OF CONTROLLING SOIL EROSION DUE TO WIND AND TRAFFIC FORCES, WHICH CAN RESULT IN EFFECTIVE DUST CONTROL MEASURES. SUCH STABILIZERS MUST BE ECONOMICAL, EASY TO APPLY IN THE FIELD AND DURABLE TO WITHSTAND VARIOUS ENVIRONMENTAL CONDITIONS IN ARID AND SEMI-ARID REGIONS OF THE STATE. IN ADDITION TO CONTROLLING SANDY SOIL PARTICULATES THAT GET PICKED UP BY THE WIND, RESEARCHERS WILL BE INTERESTED IN STABILIZING TREATMENTS TO UNPAVED SECONDARY ROADS WHICH ARE A CONTINUOUS MAINTENANCE EXPENSE BECAUSE OF THE NECESSITY FOR FREQUENT GRADING AND REPLACING GRAVEL LOST THROUGH EROSION BY TRAFFIC. STUDIES HAVE INDICATED THAT ANNUAL LOSSES OF ROAD MATERIAL CAN REACH ABOUT 200 CUBIC YARDS PER MILE FOR GRAVEL ROADS AND LOSS OF AIR-BORNE SILT AND CLAY PARTICULATES CAN RUN FIVE TONS PER MILE PER YEAR ON ROADS WHERE TRAFFIC VOLUMES REACH 250 VEHICLES PER DAY.
