BITUMEN-POLYMER PASTE Russian patent published in 2013 - IPC C08L95/00 C09D195/00 C08L23/12 C08K5/5415 C08K13/02

Abstract RU 2489463 C1

FIELD: chemistry.

SUBSTANCE: bitumen-polymer paste contains bitumen, a polymer additive, ethyl silicate and mineral filler. The polymer additive used is atactic polypropylene, the filler used is flue ash from Krasnoyarsk TPP-2, and the ethyl silicate is ethyl silicate-32. Components are in the following ratio, wt %: bitumen - 86-40; atactic polypropylene - 2-10; ethyl silicate-32 - 2-10; flue ash from Krasnoyarsk TPP-2 - the balance.

EFFECT: high heat resistance, frost resistance and low water saturation of the paste.
