Drainage asphalt mixture and preparation method thereof
The invention belongs to the technical field of road materials, provides a drainage asphalt mixture and a preparation method thereof, and solves the problems of poor drainage and low performance of an asphalt pavement. The mixture comprises the following components: modified asphalt, mineral powder, basalt fiber, C9 petroleum resin, terpene resin and skeleton aggregate. By adding the two resins, a network structure can be formed in the asphalt mixture, so that the mechanical property of the mixture is improved; and the basalt fiber plays a role in reinforcing in the mixture. The particle size of the mineral powder is extremely small, the mineral powder can be attached to the surface of an asphalt film when being added into the mixture, water flow is discharged from basalt fibers in an accelerated mode, and the phenomenon of internal water damage is avoided. The invention also provides a preparation method of the drainage asphalt mixture, which comprises the following steps: mixing the basalt fiber and the skeleton aggregate to obtain a dry mixed material; mixing the dry mixing material, the modified asphalt, the C9 petroleum resin and the terpene resin to obtain an aggregate; and mixing the aggregate with mineral powder to obtain the drainage asphalt mixture.
本发明属于道路材料技术领域，提供了一种排水沥青混合料及其制备方法，解决了沥青路面排水差、性能低的问题。该混合料包含下列组分：改性沥青、矿粉、玄武岩纤维、C9石油树脂、萜烯树脂和骨架集料。两种树脂的加入可以在沥青混合料中形成网络结构，从而提升混合料的机械性能；玄武岩纤维在混合料中发挥加筋的作用。矿粉的粒径极小，在添加进混合料中会依附在沥青膜的表面，水流加速从玄武岩纤维上排出，避免了内部水损现象的发生。本发明还提供了排水沥青混合料的制备方法，将玄武岩纤维和骨架集料混合，得到干拌料；将干拌料、改性沥青、C9石油树脂和萜烯树脂混合，得到集合料；将集合料和矿粉混合，即得所述排水沥青混合料。
