Basalt fiber reinforced iron tailing high-performance cold patch asphalt mixture and preparation method thereof
The invention discloses a basalt fiber reinforced iron tailing high-performance cold patch asphalt mixture, which is prepared from the following components in percentage by weight: 15 to 35 percent of matrix asphalt, 30 to 65 percent of coarse and fine aggregate, 0.01 to 0.03 percent of silica fume, 0.01 to 0.04 percent of mineral powder, 3 to 21 percent of iron tailing mixed sand, 0.01 to 0.05 percent of antistatic agent, 0.2 to 0.3 percent of SBS modifier, 0.3 to 0.55 percent of TLA asphalt and 3 to 9 percent of diluent, 0.3-1.2% of a cold patch additive and the balance of basalt fiber; the prepared asphalt mixture can be constructed in extreme weather and is high in adaptability, the matrix asphalt, the SBS modifier, the antistatic agent, the coarse and fine aggregate, the silica fume, the mineral powder and the like are strictly prepared according to the proportion, the quality of the asphalt mixture is superior to that of other cold patch asphalt mixtures, and through the modification effect of the SBS modifier, the cold patch asphalt mixture can be applied to the field of asphalt pavement construction. Therefore, the cold patch asphalt mixture has better strength and durability, can be tightly combined with the periphery of a pit slot, and is not easy to cause secondary diseases such as loosening and falling off.
本发明公开了一种玄武岩纤维增强铁尾矿高性能冷补沥青混合料，该破乳剂包括以下组分且各组分的占比为：基质沥青15‑35％、粗细集料30‑65％，硅灰0.01‑0.03％，矿粉0.01‑0.04％，铁尾矿混合砂3‑21％，抗静电剂0.01‑0.05％，SBS改性剂0.2‑0.3％，TLA沥青0.3‑0.55％，稀释剂3‑9％，冷补添加剂0.3‑1.2％，玄武岩纤维补充余量；本发明制备的沥青混合料可以在极端天气下施工，适应能力强，通过基质沥青、SBS改性剂、抗静电剂、粗细集料、硅灰、矿粉等严格按照配比进行制备，质量优于其他冷补沥青混合料，通过SBS改性剂的改性作用，使得冷补沥青混合料具有较好的强度和耐久性，可以与坑槽四周紧密结合，不易产生松散、脱落等二次病害。
