The invention discloses an application of known flyash-compounded channel seam permeation resistant material on preparing a road asphalt mixed material. A modified asphalt mixing material using flyash-compounded channel seam permeation resistant material as a cementation material comprises normal pulverized stone, stone crumb, sand, slag, mineral powder and the asphalt mixing material used as thecementation material. The asphalt mixing material used as the cementation material in the asphalt mixing material accounts for 30 to 100 weight parts of the asphalt weight, and is replaced by the flyash-compounded channel seam permeation resistant material and the like of the same weight parts. The asphalt mixing material prepared by using the flyash-compounded channel seam permeation resistant material as the cementation material increases the using ways of the high additional value of the flyash, reduces the economic cost of the asphalt mixing material and improves the using performance of the asphalt mixed material
