FIELD: chemistry.
SUBSTANCE: invention relates to field of road-building materials, in particular to recycling of wastes of soft roofing repair with obtaining bitumen astringent and can be applied in preparation of asphalt-concrete mixtures. Asphalt-concrete mixture contains road-metal, sand, mineral powder and bitumen astringent from wastes of soft roofing repair plasticised with straight run tar with the following component ratio, wt %: bitumen, containing to 15% of admixture of mineral filler and base fibres - 49…65, straight run tar - 51…35.
EFFECT: increase of strength limit with simultaneous reduction of receptivity of asphalt-concrete to temperatures.
