Anti-skid surface layer composite modified asphalt mixture for special road section and preparation method of anti-skid surface layer composite modified asphalt mixture
The invention relates to a special road section anti-skid surface layer composite modified asphalt mixture and a preparation method thereof, the asphalt mixture is composed of a filler, matrix asphalt, red mud, a high modulus additive, a first active component, a second active component and an aggregate, the first active component is composed of o-cresol formaldehyde epoxy resin, phenoxy resin and sepiolite; the second active component is prepared from terpene resin, polyether ketone, glass fibers and carbon fibers. According to the special road section anti-skid surface layer composite modified asphalt mixture provided by the invention, the high-temperature deformation resistance and low-temperature crack resistance of an asphalt pavement are greatly improved, and meanwhile, the pavement has excellent anti-skid and overall durability properties; the red mud asphalt pavement material can be applied to asphalt surface layer paving of special road sections such as sharp turns, S-shaped routes, long and large longitudinal slopes, tunnel entrances and exits, plane intersections and the like, meanwhile, the red mud is added, solid waste utilization can be promoted, resources are saved, and the environment is protected.
本发明涉及一种特殊路段抗滑表层复合改性沥青混合料及其制备方法，该沥青混合料由填料、基质沥青、赤泥、高模量添加剂、第一活性组分、第二活性组分和集料组成，其中第一活性组分由邻甲酚醛环氧树脂、聚酚氧树脂和海泡石组成；第二活性组分由萜烯树脂、聚醚酮、玻璃纤维和碳纤维组成。本发明提供的特殊路段抗滑表层复合改性沥青混合料在大幅提高沥青路面高温抗变形和低温抗裂性能的同时，能使路面具有优秀的抗滑以及整体耐久的性质，可应用于急转弯、S形路线、长大纵坡、隧道进出口、平面交叉口等特殊路段的沥青表层铺筑，同时加入赤泥还可以促进固体废料的利用，有利于节约资源，保护环境。
