Environment-friendly composite additive modified cement stabilized macadam mixture and preparation method thereof
The invention discloses an environment-friendly composite additive modified cement stabilized macadam mixture. The environment-friendly composite additive modified cement stabilized macadam mixture is prepared from the following raw materials in parts by weight: 75 to 90 parts of macadam, 0.3 to 1.5 parts of modified rubber powder, 0.3 to 1.0 part of nano graphene microchip, 3 to 8 parts of cement, 0.02 to 0.10 part of retarder, 9 to 16 parts of ceramic fragment, 0.3 to 2.2 parts of coconut fiber and 0.5 to 1.9 parts of salix mongolica fiber. The addition amount of the water accounts for 4.2-6.5% of the mass of the dry materials. The environment-friendly composite additive modified cement stabilized macadam mixture has the advantages of excellent pavement performance, simple preparation process and non-toxic and harmless raw materials, can improve the anti-freezing property and dry shrinkage property of a road base, and plays a significant role in prolonging the service life of an asphalt pavement; the environment-friendly composite additive modified cement stabilized macadam mixture is environment-friendly, low-carbon, wide in raw material source, free of pollution in the production process, low in price and low in cost, and has good economic and social benefits.
本发明公开了一种环保型复合外加剂改性水泥稳定碎石混合料，由下列重量份的原料制成：碎石75～90份、改性橡胶粉0.3～1.5份、纳米石墨烯微片0.3～1.0份、水泥3～8份、缓凝剂0.02～0.10份、陶瓷碎片9～16份、椰壳纤维0.3～2.2份、沙柳纤维0.5～1.9份；所述水的加入量占干料质量的4.2～6.5%。本发明环保型复合外加剂改性水泥稳定碎石混合料路用性能优良、制备工艺简单、原料无毒无害，同时可以提高道路基层抗冻性能和干缩性能，对延长沥青路面使用寿命具有重大作用；本发明环保型复合外加剂改性水泥稳定碎石混合料环保低碳，且原材料来源广泛，生产过程无污染且价格低廉、成本低，具有良好的经济、社会效益。
