国内外对MiberⅠ型矿物复合纤维沥青混合料的性能尚未有研究。鉴于此,采用车辙试验、低温弯曲试验和冻融劈裂试验研究了MiberⅠ型矿物复合纤维沥青混合料的高温稳定性、低温抗裂性和水稳定性,并与木质素纤维沥青混合料和玄武岩纤维沥青混合料的路用性能进行对比。结果表明:掺入适量MiberⅠ型矿物复合纤维可有效提高沥青混合料的路用性能;与木质素纤维和玄武岩纤维相比,MiberⅠ型矿物复合纤维在改善沥青混合料性能方面具有一定优越性;可为MiberⅠ型矿物复合纤维在沥青混合料中的应用提供依据。
Domestic and foreign Miber I-type mineral composite fiber asphalt mixture performance has not been studied. In view of this, the use of rutting test, low temperature bending test and freeze-thaw splitting test Miber Ⅰ mineral composite fiber asphalt mixture high temperature stability, low temperature crack resistance and water stability, and lignin fiber asphalt mixture and basalt Road asphalt fiber asphalt performance comparison. The results showed that MiberⅠ mineral composite fiber could improve the road performance of asphalt mixture with appropriate amount of MiberⅠ mineral composite fiber. Compared with lignin fiber and basalt fiber, Miber Ⅰ mineral fiber had some advantages in improving the performance of asphalt mixture; It provided the basis for the application of Miber Ⅰ mineral composite fiber in asphalt mixture.
