FIELD: chemistry.SUBSTANCE: invention relates to bitumen compositions and can be used for obtaining bitumen compositions, applied in road and airfield construction. Bitumen composition includes mixture of oxidised bitumen with unoxidised oil petroleum product, with application as unoxidised oil petroleum product of heavy gasoil of catalytic cracking with ratio, respectively, oxidised bitumen:heavy gasoil of catalytic cracking 95-99:5-1 wt %, with heavy bitumen having softening point equal or higher than softening point of final product.EFFECT: result consists in simplification of bitumen composition formulation with obtaining bitumen with improved quality characteristics, in particular penetration at 0°C, without losing resistance to ageing by index of change of softening point after warming-up.2 tbl, 5 ex |
