DUST-REDUCING COMPOSITIONS FOR TREATING DRY SOIL

摘要

A dust-reducing composition for treating dry soil that includes a hygroscopic compound together with a hydrophobic compound in relative amounts sufficient to form a water­ repellant surface on the soil. Also, a. process for treating dry soil to reduce dust generation due to movement of traffic or air thereover. This process includes applying onto the soil a hygroscopic compound and subsequently applying a hydrophobic compound onto the hygroscopic compound containing soil. Alternatively, the process includes applying onto the soil an aqueous solution of a mixture of a hygroscopic compound and a hydrophobic compound. In either case, the hygroscopic and hydrophobic compounds are applied in relative amounts sufficient to form a water-repellant surface on the soil.
