Abstract
1. Амфотерная присадка к битумам для приготовления асфальтобетонных смесей с использованием кислых и основных пород и их смесей, отличающаяся тем, что в ее составе используются природные фосфолипиды, обладающие амфотерными свойствами по отношению к химической сорбции на кислых и основных породах в смеси с синтетическими ПАВ амфотерного типа в следующих соотношениях, %:фосфолипиды растительных масел 50-100синтетические амфотерные ПАВ 0-502. Амфотерные присадки к битумам по п.1, отличающиеся тем, что в качестве синтетических амфотерных ПАВ используют продукты последовательной этерификации жирных кислот с триэтаноламином и фосфорным ангидридом (или ортофосфорной кислотой) или продукты последовательной этерификации диглицеридов жирных кислот сначала с фосфорной кислотой и далее с триэтаноламином или продукты конденсации смоляных кислот - дистилляционных фракций хвойного талового масла с малеиновым ангидридом.1. Amphoteric additive for bitumen for the preparation of asphalt mixtures using acidic and basic rocks and their mixtures, characterized in that it uses natural phospholipids that have amphoteric properties with respect to chemical sorption on acidic and basic rocks mixed with synthetic amphoteric surfactants type in the following ratios,%: phospholipids of vegetable oils 50-100 synthetic amphoteric surfactants 0-502. Amphoteric bitumen additives according to claim 1, characterized in that the products of sequential esterification of fatty acids with triethanolamine and phosphoric anhydride (or phosphoric acid) or the products of sequential esterification of diglycerides of fatty acids first with phosphoric acid and then with triethanol are used as synthetic amphoteric surfactants condensation products of resin acids - distillation fractions of coniferous tall oil with maleic anhydride.
