Freeze-thaw-resistant and water-erosion-resistant cold patch asphalt mixture and preparation method thereof
The invention discloses a freeze-thaw-resistant and water-erosion-resistant cold patch asphalt mixture and a preparation method thereof, and relates to the technical field of asphalt materials. When the cold patch asphalt mixture resistant to freeze thawing and water erosion is prepared, epoxy resin core polyester fibers and maleic anhydride core polyester fibers are mixed and then sequentially react with thionyl chloride and aminopropyltrimethoxysilane to prepare modified mixed polyester fibers, and the modified mixed polyester fibers and ethyl alcohol are mixed to prepare a fiber solution; and mixing the asphalt, the asphalt additive, diesel oil, the fiber solution and the limestone mineral aggregate to prepare the freeze-thaw-resistant and water-erosion-resistant cold patch asphalt mixture. The freeze-thaw-resistant and water-erosion-resistant cold patch asphalt mixture prepared by the invention has excellent waterproof performance and frost resistance.
本发明公开了一种抗冻融耐水侵蚀的冷补沥青混合料及其制备方法，涉及沥青材料技术领域。本发明在制备的抗冻融耐水侵蚀的冷补沥青混合料时，先将环氧树脂芯聚酯纤维和马来酸酐芯聚酯纤维混合后依次和氯化亚砜、氨丙基三甲氧基硅烷反应制得改性混合聚酯纤维，将改性混合聚酯纤维和乙醇混合制得纤维溶液，将沥青、沥青添加剂、柴油、纤维溶液和石灰岩矿料混合制得抗冻融耐水侵蚀的冷补沥青混合料。本发明制备的抗冻融耐水侵蚀的冷补沥青混合料具有优异的的防水性能和抗冻性能。
