Novel steel slag asphalt pavement structure

The utility model discloses a novel steel slag asphalt pavement structure which sequentially comprises a surface layer and a base layer from top to bottom, a sealing layer is further arranged between the surface layer and the base layer, the surface layer is an asphalt mixture layer, and the base layer is a steel slag asphalt mixture layer. The asphalt mixture layer sequentially comprises an upper surface layer asphalt mixture, a middle surface layer asphalt mixture and a lower surface layer asphalt mixture from top to bottom, the base layer sequentially comprises a graded broken stone layer and a cement stabilized broken stone layer from top to bottom, aggregate of the surface layer and aggregate of the base layer are both doped with steel slag aggregate, and the surface layer and the base layer are both steel slag mixture layers. Starting from the function of each layer of the asphalt pavement, the characteristics of the steel slag aggregates with different particle sizes are fully utilized, the steel slag
