FIELD: construction.
SUBSTANCE: method to produce a modifying additive includes mixing and joint mechanical activation of mineral powder from marble, SBS polymer, adhesive additive and mineral oil at the following ratio of components, wt %: adhesive additive - 0.35-0.5, mineral oil - 3.5-5.0, SBS polymer - 1.5-3.5, marble powder - balance.
EFFECT: production of an additive of homogeneous composition, with the possibility of its storage and transportation, provision of even distribution of polymer component volume in bitumen binder and in asphalt concrete mixture, when using the additive, production of asphalt concrete mixture of homogeneous solution, increased quality indices of a road surface made using the mixture.
