Basalt fiber reinforced asphalt concrete and preparation method thereof
The invention provides basalt fiber reinforced asphalt concrete and a preparation method thereof. The basalt fiber reinforced asphalt concrete comprises the following components in percentage by mass:13-25% of matrix asphalt, 53-65% of a coarse aggregate, 11-20% of a fine aggregate, 1-2% of silica fume, 2-5% of mineral powder and 6-13% of modified basalt fibers. The modified basalt fibers are basalt fibers coated with nano titanium dioxide, the modified basalt fibers are used as a reinforcing agent of the asphalt concrete, and the prepared asphalt concrete has excellent mechanical propertiesand ultraviolet aging resistance when used for asphalt pavements, and can help to absorb and degrade automobile exhaust.
本发明提供一种玄武岩纤维增强沥青混凝土及其制备方法，以质量百分比计，包括以下组分：基质沥青13～25％、粗骨料53～65％、细骨料11～20％、硅灰1～2％、矿粉2～5％、改性玄武岩纤维6～13％，所述改性玄武岩纤维为纳米二氧化钛包覆玄武岩纤维，将改性后的玄武岩纤维作为沥青混凝土的增强剂，制得的沥青混凝土用于沥青路面具有优异力学性能以及抗紫外线老化性能，并且可以帮助吸收降解汽车尾气。
