Regenerated anti-aging asphalt mixture as well as preparation method and application thereof

The invention relates to the technical field of road engineering construction, and particularly discloses a regenerated anti-aging asphalt mixture as well as a preparation method and application thereof. The regenerated anti-aging asphalt mixture comprises aggregate, an old asphalt mixture, matrix asphalt, a regenerant, an anti-aging agent and mineral powder, wherein the regenerant comprises aromatic hydrocarbon oil, waste rubber powder, walnut oil, an anti-stripping agent and auxiliary materials; the anti-aging agent is a mixture of thiocarbamate modified mica and polyphosphoric acid. The regenerated anti-aging asphalt mixture which is excellent in anti-aging effect, stable in performance and long in service life is successfully prepared by utilizing the synergistic effect of the raw materials. The method effectively solves the problems that in the prior art, after the aged asphalt in the old asphalt mixture is regenerated, the performance is unstable, the raw materials of the modifier are difficult to obtai
