Abstract: It has been established that the rational mass concentration of butadiene-methylstyrene rubber SKMS-30 in bitumen of the third structure rheological type should be 2…3 % wt., industrial sulfur 30…40 % wt., and the optimal mass concentration on the surface of the mineral powder of synthetic rubber SKMS-30 is 0.5...1.0 % wt. DTA and IR spectroscopy thermograms indicate that there is no chemical interaction at the interface between the bitumen-polymer binder and activated SKMS-30 mineral powder. The adsorption-solvation layer of butadiene-methylstyrene rubber provides effective wetting and sorption of the activated mineral powder by the bitumen polymer binder. Asphalt polymer sulfur concrete mixtures are characterized by a wide compaction range of 60…130 °С, and asphalt polymer sulfur concretes have the following quality indicators: compressive strength, MPa, at 0 °С R0 = 8...10; at 20 °C R20 = 5.0...6.5; at 75 °C R75 = 1.2...1.4; swelling, % of volume – 0; water saturation, % of volume 1.5...2.0; coefficient of thermal aging at 75 °C for 1 200 hours, Kst = 1.25. The coefficient of water resistance at water saturation for 90 days is Kvd = 0,87.

Keywords: road asphalt polymer sulfur concrete, technological and operational properties, rational areas of application.
