In this paper, we consider the possibility of joint use of polystyrene, its block copolymers and transformer oil to produce polymerasphaltconcrete. It is established that the properties of bitumen change when different polymers and their quantity are introduced into its composition. It was found that the introduction of polystyrene together with a plasticizer expands the temperature range of operation, which leads to an improvement in the physical-mechanical and hydrophysical properties of polymerasphaltconcrete. The regularities of the influence of the composition and quantity of polymers on the physical, mechanical and operational properties of asphalt concrete based on modified binders are revealed. It was found that the optimal amount of polymers and plasticizer is 3.5% and 10% of the mass of bitumen.
