Abstract

A method for the surface stabilization of sand and/or soil is provided. The method is comprised of applying an aqueous polymer dispersion to the surface layer of soil. The aqueous polymer dispersion is comprised of triesters of glycerol with lower aliphatic monocarboxylic acids, citric acid triesters with lower aliphatic monohydric alcohols and/or epoxidized triglycerides of at least partly olefinically unsaturated fatty acids as biodegradable plasticizers in aqueous polyvinyl acetate dispersions.
