摘　　要：【目的】为改善沥青路面整体路用性能,选用玄武岩纤维、木质素纤维对AC-13C沥青混合料进行复合改性。【方法】根据课题组前期的研究成果,确定纤维总掺量为0.4%,并拟定复掺方案。通过对AC-13C沥青混合料进行配合比设计,确定不同纤维复掺方案下的最佳油石比;通过开展高温抗车辙、低温抗开裂、抗水损害等试验评价复掺纤维AC-13C沥青混合料的路用性能。【结果】玄武岩纤维与木质素纤维掺配比例为2∶3时,高低温性能最优;掺配比例为3∶2时,混合料水稳定性能最优。【结论】玄武岩纤维、木质素纤维的掺入能够改善沥青路面的路用性能。[Purposes]To improve the overall road performance of asphalt pavement,basalt fiber and lignin fiber were selected for composite modification of AC-13C asphalt mixture.[Methods]Based on the research results of the previous research group,the total fiber content was determined to be 0.4%,and a composite blending plan was proposed.By designing the mix proportion of AC-13C asphalt mixture,the optimal asphalt aggregate ratio under different fiber blending schemes were determined;by conducting tests such as high-temperature resistance to rutting,low-temperature resistance to cracking,and water damage,the road performance of composite fiber AC-13C asphalt mixture was evaluated.[Findings]When the ratio of basalt fiber to lignin fiber is 2∶3,the high and low temperature performance is optimal,and when the ratio is 3∶2,the water stability performance of the mixture is optimal.[Conclusions]The addition of basalt fiber and lignin fiber can improve the road performance of asphalt pavement.
