FIELD: construction.

SUBSTANCE: multi-layer bitumen-polymer material contains a base, upper and lower layers. The base is a nonwoven polyester linen or glass tissue or glass-fibre mat. The upper layer contains mixed roof bitumen or a mixture of roof and road bitumens, a polymer modifier, a fire retardant and a mineral filler. The lower layer includes a mixture of roof bitumen, a polymer modifier and a mineral filler. The method consists in the fact that the base is pulled, processed with an impregnation composition, squeezed, then upper and lower layers are applied separately from each other onto the base. The upper layer is applied onto the base by means of a diffuser. The formed material is sent via calibrating shafts to produce required density and thickness of a material.

FIELD: construction.

SUBSTANCE: method consists in formation of layer from liquefied composition on the basis of bitumen and thermoplastic elastomer, which is realised at least in three stages. At the first stage and at least at the second stage, onto the first tape substrate and accordingly the second tape substrate, processed with silicon anti-adhesive composition, mastic on the basis of bitumen and thermoplastic elastomer is applied.
