FIELD: construction production.
SUBSTANCE: invention relates to the field of construction production in the road industry and can be used in the manufacture of asphalt concrete, including the use of nanotechnology. The granular modifying additive includes a modifying mixture and a binder. Wherein the modifying mixture consists of single-walled carbon nanotubes in the amount of 0.01-15 wt.%, multi-walled carbon nanotubes in the amount of 0.01-15 wt.%, graphene in the amount of 0.01-15 wt.%, carbon nanofibers in the amount of 0 01-15 wt.% and mineral powder - the rest, and a low-paraffin bituminous binder is used as a binder, in the following ratio, wt.%: modifying mixture 50 and binder 50. In this case, the obtained granules are dusted with cement or mineral powder, where the mass cement or mineral powder is not more than 2.5% by weight of the granules.
EFFECT: reducing the time to obtain modified asphalt concrete, as well as the convenience of transporting the modifying additive.
