FIELD: manufacture of building materials.
SUBSTANCE: invention relates to industrial construction and can be used for gluing dampproofing roll materials and dampproofing building units. Bitumen-polymer composition comprises asphalt obtained by dewaxing of goudron of West Siberian petroleum or goudron of West Siberian petroleum (92.5-94%), divinylstyrene thermoplastic elastomer with intrinsic viscosity above 1.0 dL/g (3.5-5.0%) and catalytic cracking waste (1.0-3.0%).
EFFECT: improved performance characteristics.
