FIELD: construction.
SUBSTANCE: invention relates to production of bitumen compositions containing polymer additives and intended for use in road construction. Composition of bitumen composition for asphalt concrete pavements includes mixture of bitumen and maleinized syndiotactic 1,2-polybutadiene, one uses maleinized 1,2-SPB at following ratio of components, wt%: bitumen is 100, maleinized 1,2-SPB is 1-8.
EFFECT: high adhesion properties and improved heat resistance, which increases service life of asphalt concrete pavement.
