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 wear resistance of the pavement surface layer are improved, the mechanical properties of the asphalt mixture are also improved, and the driving safety of highways is improved.
本发明提供一种煅烧铝矾土/陶粒复合集料的抗滑表层沥青混合料及其制备方法和应用。以体积百分比计，沥青混合料包括：粒径4.75‑9.5mm的陶粒10‑40％、粒径4.75‑9.5mm的煅烧铝矾土10‑40％、粒径4.75‑9.5mm的石料10‑40％、粒径0.075‑4.75mm的石料30‑50％和粒径0‑0.075mm的矿粉3‑8％，以及占上述原料总质量5.5‑7.5％的改性沥青。本发明将煅烧铝矾土/陶粒材料复合，在长期车辆轮胎作用下沥青路面仍能保持良好的表面纹理和构造，形成再生纹理，提高路面表面层的长期抗滑能力和抗磨损能力，同时兼顾提高沥青混合料的力学性能，有利于改善高速公路的行车安全。
