BITUMEN COMPOSITION CONTAINING A MIXTURE OF WAXES CONSISTING OF PETROLEUM CRUDE WAX AND FISHER-TROPSCH WAX, USE OF A MIXTURE OF WAXES IN BITUMEN COMPOSITIONS, USE OF A BITUMEN COMPOSITION IN ASPHALT COMPOSITIONS, ASPHALT COMPOSITIONS CONTAINING A BITUMEN COMPOSITION AND A METHOD OF PRODUCING ASPHALT COATINGS THEREFROM Russian patent published in 2020 - IPC C08L95/00 C08L91/08 

FIELD: chemical industry.

SUBSTANCE: invention relates to a bitumen composition containing a mixture of waxes, consisting of petroleum crude wax and Fischer—Tropsch wax, to use of a mixture of waxes in bitumen compositions, to use of bitumen composition in asphalt compositions, to asphalt compositions containing bitumen composition, and to method of producing asphalt coatings and structures from them. Bitumen composition containing at least one mixture of waxes consisting of: 20 to 80 wt % petroleum crude wax (PSW) and 20 to 80 wt % Fischer—Tropsch wax (FTW), in both cases in terms of total weight of at least one mixture of waxes.

EFFECT: technical result of claimed invention consists in creation of mixture of waxes, which would demonstrate better process properties in bitumen and in production of asphalt mixture, but would not have a significant effect on the physical properties of bitumen.
