Red mud-silicate composite anti-aging agent, asphalt mixture as well as preparation method and application of red mud-silicate composite anti-aging agent
The invention relates to the technical field of asphalt anti-aging agents. The invention relates to the technical field of asphalt, in particular to a red mud-silicate composite anti-aging agent, an asphalt mixture and a preparation method and application thereof, and the anti-aging agent is prepared from the following raw materials in parts by weight: 40-70 parts of red mud, 10-30 parts of silicate material, 1-10 parts of slaked lime, 1-10 parts of white mud and 10-20 parts of aromatic hydrocarbon oil. The performance characteristics of the red mud and silicate materials are combined, so thatthe red mud and silicate material compounded anti-aging agent can effectively improve the temperature rut resistance, the low-temperature crack resistance and the water stability of an asphalt mixture; the dynamic modulus is remarkably improved, diseases caused by aging of an asphalt pavement in the service period can be reduced, the service time of a road is prolonged, and the maintenance cost of the road is reduced.
本发明涉及沥青抗老化剂技术领域，尤其涉及赤泥‑硅酸盐复合抗老化剂、沥青混合料及其制备方法与应用，按重量份计，所述抗老化剂的原料组成包括：赤泥40‑70份，硅酸盐材料10‑30份，消石灰1‑10份，白泥1‑10份，芳烃油10‑20份。本发明结合赤泥与硅酸盐材料的性能特点，制备了赤泥与硅酸盐材料复配的抗老化剂，该抗老化剂可以有效提高沥青混合料的温抗车辙性、低温抗裂性和水稳定性，而且动态模量得到了显著提高，可以减少沥青路面在服役期间由于老化造成的病害，延长道路服役时间，降低道路维修成本。
