FIELD: chemistry.
SUBSTANCE: invention relates to additives for asphalt concrete composite mixtures for road surfaces, particularly surfactants - adhesive bitumen additives. The amphoteric adhesive bitumen binder additive comprises synergistic mixtures of phospholipids isolated from vegetable oils and synthetic amphoteric surfactants in the following ratios: phospholipids from vegetable oils - 50-100%, synthetic amphoteric surfactants - 0-50%.
EFFECT: disclosed additives are equally suitable for mineral rocks with an acidic, basic or mixed type of surfaces, which enables asphalt pavements to retain their quality for a long period of time.
