FIELD: household chemical goods.
SUBSTANCE: invention relates to rubber-bitumen mastic containing bitumen, rubber crumb, plasticizer, and extender and is characterized by that mastic further contains butadiene-nitrile rubber (92.5-4.0%) and maleic anhydride (2.0-2.5%) and by that, as plasticizer, liquid fraction of liptobiolite coal resin with boiling temperature above 230°C and, as extender, talc are used in concentrations 20.0-30.0% and 22.5-35.0%, respectively, while bitumen represents the rest of the mastic.
EFFECT: enabled achieving elevated values of elasticity and strength of mastic and its adhesion to protected material at temperature and fragility characteristics ensuring effective "operation" of mastic under severe climatic conditions.
