Basalt fiber asphalt mixture with mixed length for improving road crack resistance
The invention discloses a basalt fiber asphalt mixture with mixed length for improving road crack resistance, which comprises the following components in percentage by mass: 0.3-0.4% of fibers, 95.3%-95.5% of mineral aggregates and SBS (styrene butadiene styrene) modified asphalt accounting for 4.7%-4.9% of the total weight of the mineral aggregates, and the fiber is composed of basalt fibers withthe lengths of 3mm, 6mm and 9mm according to the mass ratio of 1-3: 13: 1-3. The basalt fibers are doped into the prepared asphalt mixture, and the basalt fibers with the diameters of 3mm, 6mm and 9mm are mixed and doped according to different proportions, so that the crack resistance of the asphalt mixture can be improved, and the problem that asphalt pavements are easy to crack and other diseases can be solved.
本发明公开了一种提升道路抗裂性能的混合长度玄武岩纤维沥青混合料，以沥青混合料的质量百分比计，该沥青混合料包括纤维0.3~0.4%和矿料95.3%~95.5%，以及占矿料总重量4.7%~4.9%的SBS改性沥青，其中，所述的纤维是以长度为3mm、6mm、9mm玄武岩纤维按质量比1~3:1~3:1~3构成。本发明在所制备沥青混合料中掺入玄武岩纤维，将3mm、6mm、9mm玄武岩纤维按不同比例混合掺入，能够提高沥青混合料抗裂性能，有利于解决沥青路面易产生裂缝等病害问题。
