Graphene-basalt fiber composite modified asphalt mixture and preparation method thereof
The invention provides a graphene-basalt fiber composite modified asphalt mixture and a preparation method thereof, and belongs to the technical field of building materials. According to the invention, the asphalt mixture is modified by adopting the graphene and the basalt fiber together, and the graphene can improve the high-temperature stability and the water stability of the asphalt mixture and has an adverse effect on the low-temperature crack resistance of the asphalt mixture, so that the basalt fiber is adopted to improve the low-temperature crack resistance of the asphalt mixture. According to the graphene-basalt fiber composite modified asphalt mixture and the preparation method thereof, the graphene and the basalt fiber are simultaneously adopted to perform composite modification on the asphalt mixture, so that complementary advantages can be realized, the pavement performance of the asphalt mixture is greatly improved, and the graphene-basalt fiber composite modified asphalt mixture has excellent pavement performance such as high-temperature stability, low-temperature crack resistance and water stability; the additive can be used for asphalt pavement engineering in seasonal frozen areas, and overcomes the defect that the performance of an asphalt mixture is improved by a single additive.
本发明提供了一种石墨烯‑玄武岩纤维复合改性沥青混合料及其制备方法，属于建筑材料技术领域。本发明采用石墨烯和玄武岩纤维共同改性沥青混合料，石墨烯能够提高沥青混合料的高温稳定性和水稳定性，而对于沥青混合料低温抗裂性则存在不利影响，因而采用玄武岩纤维提高沥青混合料的低温抗裂性。本发明同时采用石墨烯和玄武岩纤维对沥青混合料进行复合改性可实现优势互补，极大地改善了沥青混合料的路用性能，所述石墨烯‑玄武岩纤维复合改性沥青混合料具有优异的高温稳定性、低温抗裂性和水稳定性等路用性能，可用于季冻区沥青路面工程，克服了单一外掺剂对沥青混合料性能改善的不足。
