Energy saving and consumption reduction asphalt concrete modifier and preparation method thereof

The present invention belongs to the technical field of asphalt modification, and relates to an energy saving and consumption reduction asphalt concrete modifier and a preparation method thereof. The asphalt concrete modifier comprises the following component in parts by mass: 65-90 parts of sulfur, 5-10 parts of a polymer, 10-25 parts of filler, 1-5 parts of a tackifier, 0.5 -1 part of a plasticizer, 0.1-2 parts of a hydrogen sulfide inhibitor, 0.1-0.5 part of carbon powder, 0.05 to 0.1 part of an antioxidant and 30-40 parts of asphalt. Compared with the prior art, the mixing temperature is low, the sulfur is used for modifying asphalt, is energy saving and environmentally-friendly, and has very significant economic and social benefits; the process method is simple in process, a lot of processing procedures are reduced, operability is strong; equipment and raw material costs are inexpensive; operating technical conditions are mild, in the whole process, the temperature is greatly reduced, security risks during production are effectively reduced, and the asphalt concrete modifier is suitable for industrial production.
