Asphalt regenerant and preparation method thereof

The invention discloses an asphalt regenerant and a preparation method thereof, the asphalt regenerant comprises the following components in parts by mass: 90-95 parts of vacuum gas oil, 1-10 parts of oil slurry and 0.5-3 parts of an anti-aging agent, the wax content of the vacuum gas oil is lower than 2%, and the aromatic content of the vacuum gas oil is greater than 35%; the chemical components of the vacuum gas oil are basically the same as those of the asphalt, so that the vacuum gas oil and the aged asphalt have good compatibility; secondly, by controlling the content of wax and aromatics in the vacuum gas oil, the temperature sensitivity of the asphalt is remarkably reduced, so that the influence of the external environment temperature on the property of the asphalt is reduced, the performance of the regenerated asphalt can be recovered to the non-aging level, and the regenerated asphalt has excellent low-temperature performance; besides, a small amount of additive is added, so that excessive introducti
