摘　　要：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。No research has been done on the performance of MiberⅠmineral composite fiber reinforced asphalt mixture at home and abroad.In view of that,by analyzing the technical characteristic of MiberⅠmineral composite fiber,the feasibility of the fiber＇s application in asphalt mixture is evaluated.Through the rutting test,low temperature bending test and freeze-thaw splitting test,the performance of MiberⅠmineral composite fiber asphalt mixture are investigated,along with the comparsion of the improvement effects of lignin fiber and basalt fiber on the asphalt mixture.The results show that adding appropriate dosage of MiberⅠmineral composite fiber can improve the road performance of asphalt mixture effectively.Compared with lignin fiber and basalt fiber,MiberⅠmineral composite fiber demonstrates certain advantages in the improvement effect on the road performance of asphalt mixture.The research results can provide a basis for the application of MiberⅠmineral composite fiber in the asphalt mixture.
