Industrialized heat regeneration asphalt mixture and preparation method thereof

The present invention discloses a factory thermal regeneration asphalt mixture, including the components of the following weight percentages: 44 to 92 percent of novel collection material, 1 to 3 percent of mine powder, 5 to 50 percent of old asphalt mixture, and 1.7 to 3.0 percent of novel asphalt binder; therein, the weight ratio between the thin material with the particle diameter between 0 and 15 mm and the rough material with the particle diameter between 15 and 25 mm in the old asphalt mixture is from 0.5 to 2 to 1. The present invention also discloses the preparation method. The factory thermal regeneration asphalt mixture of the present invention uses no regeneration agent, which can save a large amount of asphalt and gravel material, save the project investment, change the waste into the valuable materials, and save energy; the mixture is not inferior to the fresh asphalt mixture in the high and low temperature performance and the prevention performance to the water damage; in addition, the preparati
