FIELD: construction industry; bituminous products.
SUBSTANCE: bituminous product (1) for protecting and sealing surfaces contains bitumen (3) and mineral filler. The mineral filler contains unmilled blown perlite granules (2) with closed porous surface (4), bulk density from 90 to 550 kg/m3 and particle size from 5 to 2000 microns, and blown perlite granules (2) with open porous surface (5).
EFFECT: reduced specific gravity, improved heat-insulating and mechanical properties of the bituminous product.
