High-performance asphalt mixture and preparation method thereof
The invention relates to the technical field of highway pavement engineering, in particular to a high-performance asphalt mixture and a preparation method thereof. According to the invention, the aggregate is modified by the quaternary tetraol and the glycerol, so that the aggregate is endowed with a non-polar end group, and the aggregate has excellent adhesion performance with asphalt, so that the anti-stripping performance and the stability performance of the mixture are remarkably improved; according to the present invention, through the synergistic effect of the antioxidant, the accelerator, the dispersant, the fiber reinforcing agent and the tailing aggregate, the asphalt mixture is endowed with the excellent pavement performance, and the significant social benefit is provided.
本发明涉及公路路面工程的技术领域，尤其涉及一种高性能沥青混合料及制备方法。本发明其骨料经季成四醇和甘油进行改性，赋子了骨料非极性端基，与沥青具有优异的粘附性能，从而显著提高了混合料的抗剥落性能和稳定性能，在沥青中加入适量超高分子量聚乙烯和甲基硅油进行共混改性，显著提高了沥青混合料的抗冲击性、耐磨性和耐久性，同时通过抗氧剂、促进剂、分散剂、纤维增强剂和尾矿骨料的协同作用，赋予沥青混合料优异的路用性能，具有显著的社会效益。
