Drainage type asphalt pavement mixture and preparation method thereof
The invention belongs to the technical field of drainage pavements, and provides a drainage type asphalt pavement mixture and a preparation method thereof. The product is prepared from the following raw materials in parts by mass: 2-10 parts of modified asphalt, 55-95 parts of aggregate, 2-10 parts of mineral powder, 1-6 parts of water-based resin and 1-6 parts of a titanium dioxide-graphene composite material. The modified asphalt has high bonding strength with other raw materials, so that the water damage resistance, scattering resistance and rutting resistance of the drainage asphalt pavement mixture can be greatly improved; the aggregate with specific gradation forms an embedded skeleton structure, so that the water permeability of the mixture is improved, and the overall crushing value and abrasion value are improved at the same time; the water-based resin enables a protective layer to be formed outside the mixture during use; the titanium dioxide-graphene composite material can adsorb automobile exhaust. The drainage type asphalt pavement mixture with excellent comprehensive performance is obtained by selecting the raw materials of specific types and using amounts and enabling the raw materials to cooperate with one another.
本发明属于排水路面技术领域，提供了一种排水型沥青路面混合料及其制备方法。该产品由包含下列质量份数的原料制备得到：改性沥青2～10份，集料55～95份，矿粉2～10份，水性树脂1～6份和二氧化钛‑石墨烯复合材料1～6份。改性沥青与其它原料的粘合强度高，能够大幅提高排水沥青路面混合料的抗水损害、抗飞散和抗车辙性能；特定级配的集料形成嵌挤骨架结构，在提升混合料透水性能的同时提高整体的压碎值和磨耗值；水性树脂使混合料在使用时外部形成保护层；二氧化钛‑石墨烯复合材料能够吸附汽车尾气。本发明通过选取特定种类和用量的原料，使得各原料之间相互协同，得到了一种综合性能优异的排水型沥青路面混合料。
