摘　　要：玄武岩纤维具有天然的与沥青混凝土的亲和力和耐碱性,能更有效地参与矿料和沥青混合料之间的结合。通过约束应力和冲击韧性试验,研究玄武岩纤维加筋沥青混凝土的低温抗裂性能,为玄武岩纤维在沥青路面中的推广应用提供理论依据。The basalt fiber has a natural affinity and alkali resistance with asphalt concrete. It can more effectively participate in the union between mineral aggregate and asphalt mixture. By the test of restraint stress and impact ductility, study the low temperature anti cracking performance of basalt fiber reinforced asphalt concrete, and provide a theoretical basis for the promotion and application of basalt fiber in asphalt pavement.
