Multi-scale nano-material composite diatomite modified drainage asphalt mixture and preparation method thereof
The invention discloses a multi-scale nano-material composite diatomite modified drainage asphalt mixture. The asphalt mixture is prepared from the following raw materials: mineral aggregate, asphalt,ceramic fibers, a diatomite modifier, an improver, a stabilizer, a coupling agent, organic vermiculite (OEVMT), organic montmorillonite (OMMT), nanometer silicon dioxide and nanometer aluminum oxide.The asphalt mixture has the advantages of excellent pavement performance, simple preparation process and usage of nontoxic and harmless raw materials, can enhance the high-temperature stability, low-temperature crack resistance, water stability and fatigue property of a drainage asphalt pavement, and has important meanings for prolonging the service life of the drainage asphalt pavement. The drainage asphalt mixture belongs to environment-friendly non-toxic non-corrosive materials, has the advantages of wide raw material source, no pollution in the production process and low price, and produces favorable economic and social benefits.
本发明公开了一种多尺度纳米材料复合硅藻土改性排水性沥青混合料，由下列原料制成：矿料、沥青、陶瓷纤维、硅藻土改性剂、改善剂、稳定剂、偶联剂、有机蛭石OEVMT、有机蒙脱土OMMT、纳米二氧化硅、米三氧化二铝。本发明沥青混合料路用性能优良、制备工艺简单、原料无毒无害，同时可以提高排水沥青路面高温稳定性、低温抗裂性、水稳定性以及疲劳性能，对延长排水沥青路面使用寿命具有重大意义；本发明排水性沥青混合料属于环保无毒无腐蚀类材料，且原材来源广泛，生产过程无污染，价格低廉，具有良好的经济和社会效益。
