The invention provides a cold-mixed and cold-laid asphalt mixture, and a cold-mixed and cold-laid asphalt mixture wearing layer, and belongs to the technical field of road engineering. The cold-mixedand cold-laid asphalt mixture comprises coarse aggregates, fine aggregates, high-performance modified emulsified asphalt, a mineral filler, water and a liquid additive. The asphalt mixture prepared from above cold-mixed and cold-laid material components according to a special mineral grading range can be closely bonded to an old asphalt pavement and a cement pavement; and compared with traditionalmicro-surfacing and super-sticky wearing layer materials, the mixture has higher resistance to crack, water and skid and lower driving noises.
