BITUMEN-RUBBER BINDER (EMBODIMENTS) FOR ASPHALT CONCRETE AND METHOD FOR PRODUCTION THEREOF USING MICROWAVE (EMBODIMENTS) Russian patent published in 2020 - IPC C09D195/00 C08L95/00 C04B26/26 C09D5/08

Abstract RU 2731176 C1

FIELD: chemistry; construction.

SUBSTANCE: invention relates to construction materials for motor roads and can be used in producing binder in asphalt concrete to improve physical and mechanical properties. Problem, which is solved by the proposed invention, consists in creation of a method of obtaining bitumen-rubber composite for use as binder in high-quality asphalt concrete. Bitumen-rubber binder, as embodiments of binder, contains bitumen, oil pitch, oil fuel oil and rubber crumbs at their various ratios. Binder is obtained by stirring the components using microwave heating.

EFFECT: invention increases physical and mechanical properties of the binder, such as softening temperature, brittleness temperature and extensibility.
