Anti-freezing asphalt mixture and preparation method thereof
The invention relates to the technical field of pavement materials, and particularly discloses an anti-icing asphalt mixture and a preparation method thereof. The anti-freezing asphalt mixture is prepared from the following raw material components in parts by weight: 8 to 15 parts of butadiene styrene rubber modified asphalt, 50 to 72 parts of coarse aggregate, 8 to 24 parts of fine aggregate, 5 to 10 parts of nano silicon dioxide modified polyacrylonitrile fiber and 3 to 7 parts of a modified anti-freezing agent, the modified anti-freezing agent is sodium chloride coated with hydroxy propyl cellulose and white carbon black. By adding the modified anti-freezing agent, ice and snow on the asphalt pavement can be durably melted, and the anti-freezing performance of the asphalt pavement is improved.
本申请涉及路面材料技术领域，具体公开了一种抗凝冰沥青混合料及其制备方法。一种抗凝冰沥青混合料，按重量份计，沥青混合料的制备原料包括如下组分：丁苯橡胶改性沥青8‑15份、粗骨料50‑72份、细骨料8‑24份、纳米二氧化硅改性聚丙烯腈纤维5‑10份和改性抗凝冰剂3‑7份；所述改性抗凝冰剂为羟丙基纤维素和白炭黑包覆的氯化钠。本申请通过加入改性抗凝冰剂，能够持久地融化沥青路面的冰雪，提高了沥青路面的抗凝冰性能。
