Multi-dimensional composite modified asphalt mixture and preparation method thereof
The invention provides a multi-dimensional composite modified asphalt mixture and a preparation method thereof, and aims to solve the technical problems that the pavement performance of an existing asphalt mixture is poor, and an asphalt pavement prepared from the asphalt mixture is difficult to be poor in high and low temperature performance and is seriously damaged by water. The composite modified asphalt mixture is prepared from the following raw materials in parts by weight: 80 to 120 parts of mineral aggregate, 5 to 6 parts of asphalt, 0.03 to 0.07 part of nano organic bentonite, 0.0005 to 0.0015 part of acorn, 0.004 to 0.008 part of graphene oxide and 0.10 to 0.14 part of polyurethane. The composite modified asphalt mixture provided by the invention belongs to an environment-friendly, non-toxic and non-corrosive composite asphalt mixture and has excellent pavement performance, and the tensile strength, compressive strength, shear strength, aging resistance, rutting resistance and fatigue resistance of the asphalt mixture can be remarkably improved; the mixing uniformity, the compaction property, the pavement flatness and the like of the asphalt mixture are improved, and the service life of the asphalt pavement can be prolonged; and the raw materials are wide in source, non-toxic and harmless, pollution-free in production process, low in price and good in economic benefit.
本申请提供一种多维复合改性沥青混合料及其制备方法，旨在解决现有沥青混合料的路用性能不佳及由其制成的沥青路面难高低温性能差及水损坏严重的技术问题。该复合改性沥青混合料由以下重量份的原料制成：矿料80～120份、沥青5～6份、纳米有机膨润土0.03～0.07份、橡维联0.0005～0.0015份、氧化石墨烯0.004～0.008份、聚氨酯0.10～0.14份。本申请提供的复合改性沥青混合料属于环保无毒无腐蚀类复合沥青混合料，路用性能优良，可以显著提高沥青混合料的抗拉强度、抗压强度、抗剪强度、抗老化性能、抗车辙性能、抗疲劳性能；改善沥青混合料的拌合均匀性、压实性和路面平整度等，能延长沥青路面使用寿命；且原料来源广泛、无毒无害，生产过程无污染且价格低廉，经济效益良好。
