Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a stirring device for preparing rubber asphalt. Background Art

[0002] Rubber asphalt is made by first processing the original material of waste tires into rubber powder, then combining them according to a certain coarse and fine gradation ratio, adding a variety of high polymer modifiers, and fully mixing them under high temperature conditions (above 180°C) to fully melt and swell with the base asphalt. Rubber asphalt has high temperature stability, low temperature flexibility, anti-aging, anti-fatigue, and water damage resistance. It is an ideal environmentally friendly pavement material and is mainly used in the stress absorption layer and surface layer of road structures.
