Regenerated composite fiber asphalt mixture and preparation method thereof
The invention relates to the technical field of asphalt, and particularly discloses a regenerated composite fiber asphalt mixture and a preparation method thereof.The regenerated composite fiber asphalt mixture comprises a matrix asphalt mixture and regenerated composite fibers, the mixing amount of the regenerated composite fibers is 0.3%, the asphalt-aggregate ratio of the matrix asphalt mixture is 4.8%-4.95%, and the mixing amount of the regenerated composite fibers is 0.3%. The regenerated composite fiber is one of regenerated polyester fiber, regenerated tire curtain fiber and regenerated paper fiber. According to the invention, the regenerated composite fibers are uniformly distributed in the asphalt mixture, so that bridging and reinforcement effects are well achieved, and the high-temperature stability, low-temperature crack resistance, water damage resistance and fatigue resistance of the asphalt mixture are integrally improved.
本发明涉及沥青技术领域，具体公开了一种再生复合纤维沥青混合料及其制备方法，该再生复合纤维沥青混合料，包括基质沥青混合料和再生复合纤维，其中，再生复合纤维的掺量为0.3％，基质沥青混合料的油石比为4.8％‑4.95％，所述再生复合纤维为再生聚酯纤维、再生轮胎帘子纤维以及再生纸纤维中的一种。本发明将再生复合纤维均匀分布在沥青混合料中，很好地起到桥接和加筋作用，整体提高了沥青混合料的高温稳定性、低温抗裂性、抗水损害能力、抗疲劳性能。
