Coal gangue-powder sepiolite fiber-nano aluminum nitride composite modified asphalt mixture and preparation method thereof
The invention provides a coal gangue-powder sepiolite fiber-nano aluminum nitride composite modified asphalt mixture and a preparation method thereof, and aims to solve the technical problem that the pavement performance is difficult to improve when coal gangue waste materials are applied to asphalt mixtures. The composite modified asphalt mixture is prepared from the following raw materials in parts by weight: 100 parts of mineral aggregate, 3 to 7 parts of asphalt, 0.05 to 0.12 part of coal gangue powder, 0.02 to 0.08 part of sepiolite fiber, 0.09 to 0.21 part of nano aluminum nitride and 0.013 to 0.032 part of modifier. The composite modified asphalt mixture belongs to environment-friendly, non-toxic and non-corrosive composite asphalt, has excellent pavement performance (can improve the high-temperature stability, low-temperature crack resistance and water stability of an asphalt pavement) and is simple in preparation process, the raw materials are non-toxic, harmless and wide in source, and the service life of the asphalt pavement can be prolonged; the production process is pollution-free, the price is low, the cost is low, good economic and social benefits are achieved, and resource utilization of green and environment-friendly materials in asphalt pavement engineering is further widened.
本申请提供一种煤矸石‑粉海泡石纤维‑纳米氮化铝复合改性沥青混合料及其制备方法，旨在解决煤矸类废弃材料应用于沥青混合料路用性能难以改善的技术问题。该复合改性沥青合料由以下重量份的原料制成：矿料100份，沥青3～7份，煤矸石粉0.05～0.12份，海泡石纤维0.02～0.08份，纳米氮化铝0.09～0.21份，改性剂0.013～0.032份。本申请复合改性沥青混合料属于环保无毒无腐蚀类复合沥青，路用性能优良（可提高沥青路面的高温稳定性、低温抗裂性以及水稳定性）、制备工艺简单、原材料无毒无害且来源广泛，能延长沥青路面使用寿命；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，有利于进一步拓宽绿色环保材料在沥青路面工程中的资源化利用。
