FIELD: road, industrial and civil building, in particular sealing and hydraulic insulating material. ^ SUBSTANCE: invention relates to industrial method for production of modified bitumen mastic. Claimed bitumen-polymer material contains (mass %) oil bitumen 60-70; synthetic resin 2-10; oil solvent and/or black oil 18-30; sulfur-containing compounds 0.5-5.0; and additionally oxyethylated alkylphenol as surfactant 0.1-5.0. Sulfated mixture of oil bitumen, synthetic resin, oil solvent and/or black oil treated for sulfitation at 140-2300C is used as sulfur-containing compounds. Method for production of said material also is disclosed. ^ EFFECT: polymer-modified bitumen mastic and sealing of improved quality; method for production of increased capability; inexpensive raw materials; energy-conversation technology. ^ 6 cl, 3 ex, 4 tbl, 1 dwg |
