Regenerant adding system for asphalt regenerating stirring equipment

The utility model discloses a regenerant adding system for asphalt regenerating stirring equipment. The system is characterized by comprising a regenerant storing tank, a metering device, a milling material metering bin and a system control device, wherein a conveying pipeline is arranged between the regenerant storing tank and the metering device; a pumping device, a pneumatic three-way valve and a return pipeline are arranged on the conveying pipeline; and the metering device is connected with the milling material metering bin through a flexible pipe. Compared with the prior art, the regenerant adding system disclosed by the utility model has the advantages that old asphalt pavement milling materials high in aging degree can be effectively recycled; through regenerant adding, the quality performance of new asphalt mixture pavements is increased and the service life of the pavements is prolonged; the quality performance of the new asphalt mixture pavements is avoided being influenced by the aging of the old
