road-building materials. SUBSTANCE: bitumen, diene-styrene bloc-copolymer, and industrial oil are mixed and homogenized at 110-200 C using recirculation of liquid medium in recirculation circuit comprising at least asphalt heater, pump, and caviation-cumulation treatment chamber, wherein hydrodynamic cavitation is accomplished within a frequency range of 10 to 80 Hz. EFFECT: increased degree of homogenization and extended working capacity temperature range (from melting point to brittle temperature). 2 dwg, 1 tbl
