Technical Field

[0001] The utility model relates to the field of blending devices, in particular to a matrix asphalt additive blending device. Background Art

[0002] Base asphalt is a black or dark brown colloidal substance, composed of asphalt and mineral filler. It is one of the commonly used materials in road construction and can be used to pave road surfaces or make asphalt concrete. Before using the base asphalt, it is necessary to use a blending device to add an appropriate amount of additives to the base asphalt and blend the additives with the base asphalt to improve the stability of the base asphalt. The existing blending device, during use, usually uses a screw to stir the base asphalt in the blending chamber. Since the screw has less contact with the base asphalt during the stirring process, the blending and stirring of the base asphalt is not sufficient. Therefore, we propose a base asphalt additive blending device to solve the above problems. Utility Model Content
