COMPOSITION OF MIXTURE FOR ASPHALT CONCRETE Russian patent published in 2015 - IPC C04B26/26 C08L95/00 B82B1/00 C04B111/20 

FIELD: construction.

SUBSTANCE: composition of mixture for asphalt concrete, which contains crushed stone, sand, bitumen and a carbon additive, contains crushed stone with particle size of 5-15 mm, bitumen BND 90/130, as sand - quartz feldspar sand with fineness modulus 3, as a carbon additive - carbon nanomaterials obtained as a by-product at plasma treatment of coal in a plasma reactor and having bulb-shaped and threadlike carbon structures, with their preliminary distribution in bitumen heated up to 130-140°C in the quantity of 0.03-0.06 wt % of the above mixture and additional mineral powder MP-1 at the following component ratio, wt %: above said crushed stone 42-44, above said sand 48-50, mineral powder MP-1 8-9, above said bitumen 5.4-5.6 (above mineral part).

EFFECT: increasing strength of asphalt concrete for compression, reducing flow rate of carbon nanomaterials as part of asphalt concrete.
