The invention discloses a foam warm mixing recycled asphalt mixture, a preparation method and a performance evaluation method. The mixture is a mixture formed by recycled waste and a foam modified asphalt mixture. A lower milled material of an asphalt pavement is used as a raw material, no additional recycling agent is needed, the construction temperature can be reduced by 20 to 30 DEG C by utilizing foam asphalt and warm mixing technology, the energy consumption during the construction process is reduced, the resource is saved, the environment is protected, the finally prepared mixture can be reused for the lower layer of the asphalt pavement, various technical indexes can meet the requirement, and the preparation cost is reduced.
