[0002] As road traffic continues to increase, asphalt road damage is becoming increasingly prominent. The renovation of old asphalt roads generates a large amount of waste material, which still has high value as road materials. Therefore, asphalt pavement recycling is becoming increasingly important. Cold asphalt pavement recycling involves milling and breaking up the old pavement structure, including the surface layer and part of the base layer, at room temperature, adding recycled materials, mixing them, and then resurfacing the road surface.
