FIELD: road building materials.
SUBSTANCE: bitumen of specified brands is subjected to post-oxidation using air blowing at 200-230°C to achieve desired binder softening temperature, after which 12-15% solution of butadiene/styrene or butadiene synthetic rubber in mixture of kerosene and mazut at ratio (0.3-0.4):(0.7-0.6) is added to post-oxidized bitumen at 180-190°C and oxidation is then continued at the same temperature until desired brand of binding agent is obtained.
EFFECT: simplified technology, improved environmental condition, and improved physicochemical characteristics of product.
