Composite modified asphalt mixture and preparation method thereof
The invention provides a 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 poor in high and low temperature resistance and serious in water damage. The composite modified asphalt mixture is prepared from the following raw materials in parts by weight: 80 to 120 parts of mineral aggregate, 3 to 8 parts of asphalt, 0.08 to 0.15 part of nano boron nitride, 0.05 to 0.10 part of sepiolite fiber, 0.16 to 0.32 part of high styrene rubber and 0.002 to 0.009 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, has excellent pavement performance, can enhance the high-temperature stability, low-temperature crack resistance and water stability of an asphalt pavement, can prolong the service life of the asphalt pavement, and is wide in raw material source, non-toxic and harmless, free of pollution in the production process and low in price; and good economic benefits are achieved.
本申请提供一种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差及由其制备得到沥青路面的抗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3～8份、纳米氮化硼0.08～0.15份、海泡石纤维0.05～0.10份、高苯乙烯橡胶0.16～0.32份、偶联剂0.002～0.009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，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，具有良好的经济效益。
