Asphalt mixture based on buton rock asphalt-nano material composite modification and preparation method thereof
The invention provides an asphalt mixture based on buton rock asphalt-nano material composite modification and a preparation method thereof, and aims to solve the technical problems of poor pavement performance of an existing asphalt mixture and serious high and low temperature diseases and water damage of a formed asphalt pavement. The composite modified asphalt mixture is prepared from the following raw materials in parts by weight: 80 to 120 parts of mineral aggregate, 4 to 6 parts of asphalt, 1 to 1.5 parts of buton rock asphalt, 0.02 to 0.03 part of nano carbon fiber, 0.2 to 0.3 part of nano titanium dioxide and 0.01 to 0.015 part of coupling agent. The composite modified asphalt mixture provided by the invention belongs to an environment-friendly, non-toxic and non-corrosive composite asphalt mixture, is excellent in pavement performance, can enhance the high-temperature stability, low-temperature crack resistance and water stability of an asphalt pavement, also can enhance the mechanical strength, impact resistance and stability of the asphalt mixture, has great significance in prolonging the service life of the asphalt pavement, and is worthy of popularization and application. The raw materials are non-toxic and harmless and wide in source, the production process is free of pollution and low in price, and good economic benefits are achieved.
本申请提供一种基于布敦岩沥青‑纳米材料复合改性的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差及所形成的沥青路面的高低温病害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4～6份，布敦岩沥青1～1.5份，纳米碳纤维0.02～0.03份，纳米二氧化钛0.2～0.3份，偶联剂0.01～0.015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，可以增强沥青路面高温稳定性、低温抗裂性、水稳定性，同时加强沥青混合料的机械强度、抗冲击性和稳定性，对延长沥青路面使用寿命具有重大意义，且原料无毒无害，原材料来源广泛，生产过程无污染且价格低廉，具有良好的经济效益。
