Method and chemical composition for soil stabilization and dust control
Abstract
A heterogeneous mixture produced by blending aliphatic or cyclic organic compounds with carboxylic acids of chemical structure R-COOH and applied to soils in a manner to produce high levels of dust and erosion control, and soil stabilization. Alternatively, a heterogeneous mixture may be produced by blending aliphatic or cyclic organic compounds with polyolefins of chemical structure CnH2n or R-C2nH3n, and applied to soils in a manner to produce high levels of dust control and soil stabilization. The aliphatic and cyclic compounds act as plasticizers and carriers for the carboxylic acids or polyolefin compounds. When applied to soil the carrier provides a mechanism for the carboxylic acid or polyolefin to penetrate the soil and also acts as a dust suppressing weighting agent. The plasticized carboxylic acid and/or polyolefin provides a durable, reworkable binder that associates small particulates while stabilizing soil and aggregate.
