Cold-mixed asphalt and cold-mixed cover-face mixture based on waste asphalt pavement material

The invention discloses cold-mixed asphalt and a cold-mixed cover-face mixture based on a waste asphalt pavement material, and belongs to the field of road engineering. The cold-mixed asphalt is prepared by mixing an active regeneration additive and 90# pavement petroleum asphalt according to a weight ratio of 1:(0.9-1.1). The aggregate of the cold-mixed cover-face mixture is mainly the waste asphalt pavement material. Compared with the prior art, the cold-mixing asphalt provided by the invention can activate the activity of old asphalt in the waste asphalt pavement material, has a good bonding effect, and exerts an active effect on the use durability of the mixture. The cold-mixed cover-face material has good elasticity and self-healing capability and can reduce the reflection cracks of pavement construction, and the material has good waterproof capability, can reduce the invasion of road-surface water on the base course, and can prolong the service life of roads. 本发明公开了种冷拌沥青及基于废旧沥青路面材料的冷拌罩面混合料，属于道路工程领域。所述冷拌
