Asphalt mixture doped with flocculent basalt fibers
The invention provides an asphalt mixture doped with basalt flocculent fibers. The asphalt mixture comprises the following components in percentage by mass: SBS (styrene-butadiene-styrene) modified asphalt with the amount accounting for 4.2-6.6% of the specific gravity of the mixture, basalt flocculent fibers with the total doping amount accounting for 0.3-0.45% of the specific gravity of the mixture, and a mineral aggregate with the amount accounting for 93-95.4% of the total weight of the mixture, wherein the mineral aggregate comprises coarse aggregate, fine aggregate and mineral powder, and the coarse aggregate and the fine aggregate are basalt. The invention also provides a preparation method of the asphalt mixture, the basalt flocculent fiber is doped into the prepared asphalt mixture, so that the asphalt-aggregate ratio of the asphalt mixture is increased, the low-temperature performance of the asphalt mixture is improved, the problems of ruts, cracks and other diseases of an asphalt pavement are solved, the asphalt mixture has great significance in improving the use quality of the pavement and prolonging the service life of the asphalt pavement, the comprehensive performance is good, and the economic benefit is excellent.
本发明提供一种掺加玄武岩絮状纤维的沥青混合料，以质量百分比计，所属混合料包括如下组分：SBS改性沥青占混合料比重的比例4.2～6.6％、玄武岩絮状纤维总掺量占混合料比重的比例0.3～0.45％；矿料占混合料总重的比例93～95.4％，所述矿料包括粗集料、细集料和矿粉，粗细集料材质为玄武岩。还提供了其制备方法，是通过在所制备沥青混合料中掺入玄武岩絮状纤维，有利于提高沥青混合料的油石比，提高沥青混合料的低温性能，有利于解决沥青路面车辙、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有较大意义，而且综合性能好，经济效益优。
