Anti-skid surface asphalt mixture of calcined bauxite/ceramsite composite aggregate as well as preparation method and application of anti-skid surface asphalt mixture

The invention provides an anti-skid surface asphalt mixture of calcined bauxite/ceramsite composite aggregate as well as a preparation method and application of the anti-skid surface asphalt mixture. The asphalt mixture is prepared from the following raw materials in percentage by volume: 10 to 40 percent of ceramsite with the particle size of 4.75 to 9.5 mm, 10 to 40 percent of calcined bauxite with the particle size of 4.75 to 9.5 mm, 10 to 40 percent of stone with the particle size of 4.75 to 9.5 mm, 30 to 50 percent of stone with the particle size of 0.075 to 4.75 mm, 3 to 8 percent of mineral powder with the particle size of 0 to 0.075 mm and modified asphalt which accounts for 5.5 to 7.5 percent of the total mass of the raw materials. According to the invention, the calcined bauxite/ceramsite material is compounded, so that the asphalt pavement can still keep good surface texture and structure under the long-term action of vehicle tires, regenerated texture is formed, the long-term skid resistance and w
