Asphalt pavement structure with uniform heat distribution and preparation method of each layer of material

The invention belongs to the technical field of pavement structures, and provides an asphalt pavement structure with uniform heat distribution and a preparation method of each layer of material. The asphalt pavement structure sequentially comprises an upper cooling surface layer, a middle high heat conduction surface layer and a lower heat absorption surface layer from top to bottom; the upper cooling surface layer is a colored drainage asphalt mixture layer with the thickness of 3-5cm, the middle high heat conduction surface layer is a high heat conduction structure layer containing broken copper slag and aluminum oxide, and the thickness is 5-7cm; and the lower heat absorption surface layer is a heat absorption structure layer containing a composite phase-change material, and the thickness is 7-9cm. Structural layers with different functions are combined to form linkage, a temperature field can be actively adjusted, heat is evenly distributed in the structure, the temperature difference of all the layers is
