Bituminous mixture mixed with chopped and flocculent basalt fibers and preparation method of bituminous mixture
The invention relates to an asphalt mixture mixed with chopped and flocculent basalt fibers and a preparation method, and the asphalt mixture is prepared from the following components in percentage by mass: 93 to 95.4 percent of mineral aggregate, 0.3 to 0.45 percent of mixed fibers and 4.2 to 6.6 percent of SBS modified asphalt; the mineral aggregate comprises coarse aggregate, fine aggregate and mineral powder, and the coarse aggregate is basalt; the chopped basalt fiber and the flocculent basalt fiber are both modified by a coupling agent Si-69, KH350 or KH572; the chopped basalt fibers and the flocculent basalt fibers are mixed and doped into the prepared asphalt mixture, so that the high and low temperature performance and the water damage resistance of the asphalt mixture can be improved, the problems of ruts, cracks and other diseases of an asphalt pavement can be solved, and the asphalt mixture has great significance in improving the use quality of the pavement and prolonging the service life of the asphalt pavement; and the comprehensive performance is better, and the economic benefit is better.
本发明涉及混掺短切和絮状玄武岩纤维的沥青混合料及制备方法,以质量百分比计算,包括质量分数为93‑95.4%的矿料、质量分数为0.3‑0.45%的混掺纤维以及质量分数为4.2‑6.6%的SBS改性沥青;所述矿料包括粗集料、细集料和矿粉,粗集料材质为玄武岩;短切玄武岩纤维和絮状玄武岩纤维均通过Si‑69、KH350或KH572偶联剂改性;通过在所制备的沥青混合料中混合掺入短切玄武岩纤维和絮状玄武岩纤维,有利于提高沥青混合料的高、低温性能和抗水损坏性能,有利于解决沥青路面的车辙、裂缝等病害问题,对提高路面使用品质、延长沥青路面使用寿命具有较大意义,而且综合性能更好,经济效益更优。
