ROLLED SELF-ADHESIVE BITUMEN-CONTAINING MATERIAL AND METHOD OF ITS PRODUCTION Russian patent published in 2011 - IPC C08L95/00 C09D195/00 D06N5/00 

FIELD: construction.

SUBSTANCE: method of rolled bitumen-containing material production includes impregnation of a base with a bituminous composition, prepared by melting and dehydration of the mixture of oil road viscous bitumen with oil construction or insulating bitumen, softening temperature of which is at least 70°C. The melt is cured at the temperature of 120-170°C for 4-8 hours. In process of the composition preparation its softening temperature is evaluated, results of which are used to correct the composition of by addition of one of the components, which provides the composition softening temperature corresponding to the range from 50°C to 71°C. At the same time the bituminous composition is characterised by the following ratio of components, wt %: oil road viscous bitumen - 5-88, oil construction or insulation bitumen - 9-80, plasticising oil - 1-28, such as industrial oil or flax polymerised oil. Also a rolled material is proposed.

EFFECT: finished self-adhesive rolled bitumen-containing material is characterised by improved physical and mechanical properties.
