POLYMER STABILIZATION OF SANDY SOILS FOR EROSION CONTROL

The usefulness of a number of polymeric materials in increasing the resistance of cohesionless sandy soils to wind and water erosion was studied. Erosion resistance, compressive strength, and permeability of treated soil samples were measured. Film properties of individual polymers were also studied. These properties were then related to the performance of the polymer in controlling erosion. The optimum dilution of polymer with water and the quantity of polymer required to provide a nonerosive surface were determined for three different soils. A copolymer of butadiene-styrene is suggested as an ideal polymer for controlling erosion without significantly reducing the permeability of the treated soil. Other polymers such as polyvinyl acetate and acrylic polymers were found to be water sensitive in various degrees and consequently did not perform well. From a practical viewpoint, the application of polymers to soils by spraying has an obvious advantage over mechanically mixing polymers and soils. In the study it was found that less polymer is required to provide nonerosive surface if spraying is used. In addition, aqueous-base polymers have numerous advantages over solution-base polymers.
