摘要:
 为改进沥青路面的路用性能,把玄武岩和水镁石纤维以不同配合比加入到沥青混合料中。分别按照玄武岩:水镁石纤维质量比1∶4,2∶3,3∶2,4∶1设计试验,另外再设计只掺加玄武岩纤维、只掺加水镁石纤维和不掺加纤维三组试验作为对比。然后将这七组不同配合比的沥青混合料进行高温车辙试验,小梁弯曲试验,冻融劈裂试验,确定其高温稳定性、低温抗裂性、水稳定性。通过对这七组试验研究得出:玄武岩与水镁石纤维加入到沥青混合料中,对其性能有很大改善,当掺量60%玄武岩和40%水镁石纤维时沥青混合料的效果最好。
Abstract:
 In order to improve the pavement performance of asphalt pavement, basalt and brucite fibers are added into asphalt mixture at different ratios. Based on the basalt: brucite fiber mass ratio of 1:4, 2:3, 3:2, and 4:1, the experiments were designed respectively. In addition, the three groups of experiments with only basalt fiber, only brucite fiber and no fiber were designed for comparison. Then the wheel track test, trabecular bending test and frozen-thaw cycle test were carried out to determine the high temperature stability, low temperature cracking resistance and water stability of the asphalt mixture with different mix ratios in these seven groups. Through the seven groups of experimental study, it has found that when basalt and brucite fiber were added into the asphalt mixture, its performance has a great improvement, and when there are the content of 60% basalt and 40% brucite fiber asphalt mixture is the best effect.
