FIELD: chemistry.
SUBSTANCE: invention relates to asphalt compositions and asphalt concrete. The invention relates to an asphalt compositions containing: naphthenic asphalt and a block-copolymer containing diene groups which form a block characterised by content of a 1,2-vinyl component of at least 15 wt % and less than 35 wt %. The invention also relates to asphalt concrete.
EFFECT: reduced cracking and creep rapture of the road surface.
