FIELD: road building materials.
SUBSTANCE: invention relates to preparing sealing compositions based on petroleum road bitumen and polymer used for waterproofing in road building. The proposed bitumen composition comprises the following components, wt.-%: road petroleum bitumen, 59.2-62.0; styrene butadiene-styrene thermoelastoplastic, 1.5-2.0; organic solvent, 13.5-18.0; solid residue after pyrolysis of car tires, 10.0-12.0; rubber crumbs, 10.0-12.0, and adhesion addition agent BP-KSP, 0.8-1.0. Invention provides preparing high-quality material for sealing cracks in asphalt concrete coatings that shows enhanced values of thermal stability, increases stretch ability and elasticity at low temperatures and enhanced resistance against atmosphere factors.
EFFECT: improved and valuable properties of composition.
