FIELD: road building materials.
SUBSTANCE: ground polymer and rubber solution are introduced into binder, such as bitumen, under heating up to working temperature and stirring. As polymer polyethylene therephthalate waste is used, wherein said waste is preliminary heat destructed at 265-289°C for 15-20 min followed by melt conditioning at 295-315°C for 25-35 min, cooling, drying and solid melt grinding to produce powder with particle size of 0.001-0.071 and followed by introducing thereof into binder in amount of 1.0-5.0 mass % based on binder mass. Solution of polybutadiene rubber as plasticizer is used in amount of 1.6-1.9 mass % based on binder mass.
EFFECT: composition of improved working characteristics.
