Plant fiber-nano titanium carbide composite modified asphalt mixture and preparation method thereof
The invention provides a plant fiber-nano titanium carbide composite modified asphalt mixture and a preparation method thereof, and aims to solve the technical problem of reducing high and low temperature diseases and water damage of an asphalt pavement while ensuring the pavement performance of the asphalt mixture. The composite modified asphalt is prepared from the following raw materials in parts by weight: 100 parts of mineral aggregate, 3 to 7 parts of asphalt, 0.02 to 0.08 part of cotton straw fiber, 0.09 to 0.21 part of coconut fiber, 0.03 to 0.07 part of nano titanium carbide, 0.013 to 0.032 part of modifier and 0.12 to 0.28 part of stabilizer. The composite modified asphalt mixture is excellent in performance, simple in preparation process and non-toxic and harmless in raw materials, can improve the high-temperature stability, low-temperature crack resistance and water stability of the asphalt pavement, and has great significance in prolonging the service life of the asphalt pavement; the composite modified asphalt mixture belongs to environment-friendly, non-toxic and non-corrosive composite asphalt, has the advantages of wide raw material source, no pollution in the production process, low price and low cost, and has good economic and social benefits.
本申请提供一种植物纤维‑纳米碳化钛复合改性沥青混合料及其制备方法，旨在解决保证沥青混合料的路用性能的同时减少沥青路面的高低温病害及水损坏的技术问题。该复合改性沥青由以下重量份的原料制成：矿料100份，沥青3～7份，棉秸秆纤维0.02～0.08份，椰壳纤维0.09～0.21份，纳米碳化钛0.03～0.07份，改性剂0.013～0.032份，稳定剂0.12～0.28份。该复合改性沥青混合料性能优良、制备工艺简单、原料无毒无害，同时可以提高沥青路面的高温稳定性、低温抗裂性以及水稳定性，对延长沥青路面使用寿命具有重大意义；该复合改性沥青混合料属于环保无毒无腐蚀类复合沥青，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。
