The invention relates to the technical field of asphalt concrete, in particular to an anti-crack asphalt mixture and a preparation method thereof. The anti-crack asphalt mixture is prepared from the following components in parts by weight: 250 to 300 parts of fine aggregate; 1400 to 1600 parts of coarse aggregate; 300 to 600 parts of a recycled asphalt material; 150 to 250 parts of mineral powder; 130 to 140 parts of asphalt; 3 to 5 parts of a binder; 0.6 to 1.1 parts of an anti-stripping agent; and 50 to 80 parts of a modified fiber filler. The modified fiber filler is prepared by the following steps: a, mixing basalt fiber and glass fiber, performing heating, and freeze-drying to obtain mixed fibers; and b, performing surface treatment on the mixed fibers, and mixing the mixed fibers with a modification liquid to prepare the modified fiber filler, wherein the modification liquid is composed of molten resin and filler; and the molten resin is composed of epoxy resin, amino resin and saturated polyester resin. The asphalt mixture disclosed by the invention has the advantage of high crack resistance.
本申请涉及沥青混凝土技术领域，尤其涉及一种抗裂沥青混合料及其制备方法。一种抗裂沥青混合料，由如下重量份数的组分组成：细骨料250‑300份；粗骨料1400‑1600份；再生沥青料300‑600份；矿粉150‑250份；沥青130‑140份；粘结剂3‑5份；抗剥落剂0.6‑1.1份；改性纤维填料50‑80份；改性纤维填料由以下步骤制得：a、将玄武岩纤维与玻璃纤维混合加热后，冷冻干燥，制得混合纤维；b、对混合纤维进行表面处理后，与改性液混合，制得改性纤维填料；所述改性液由熔融树脂和填料组成；所述熔融树脂由环氧树脂、氨基树脂、饱和聚酯树脂组成。本申请的沥青混合料，具有高抗裂性的优点。
