FIELD: construction.
SUBSTANCE: invention relates to a modified binder for production of asphalt-concrete mixtures, including road oil bitumen according to GOST 22245-90, produced in processing of a pipeline mixture of high-gravity oils and an additive, the additive in the binder for production of asphalt-concrete mixtures is a natural pyrobitumen with ring-and-ball softening point (RandB) within the limits of 118-160°C and with depth of needle penetration at 25 °C, equal to 0×0.1 mm at the following ratio, wt %: road oil bitumen according to GOST 22245-90 85-99, natural pyrobitumen 15-1.
EFFECT: improved dynamic properties of asphalt concretes, expansion of resource base for production of binders, having all complexes of properties put forth to bitumens.
