摘　　要：通过弯曲疲劳试验,对比分析研究了玄武岩纤维道面混凝土和普通道面混凝土的弯曲疲劳性能,并得出疲劳方程。试验结果表明:掺入玄武岩纤维后能明显提高普通道面混凝土的抗弯曲疲劳性能,玄武岩纤维道面混凝土的疲劳寿命是普通道面混凝土的2.15～5.95倍,且疲劳寿命均服从两参数威布尔分布。本文的试验研究结果为玄武岩纤维在机场道面混凝土中的实际应用提供了依据。Analyze and compare with the bending fatigue properties of basalt fiber reinforced concrete for airport pavement and plain pavement eoncrete by bending fatigue testing in laboratory, and obtains the fatigue equation. Test results indicate that the anti-fatigue property of pavement concrete can be improved evidently by the basalt fiber being mixed into, fatigue life of basalt fiber reinforced pavement concrete is 2. 15 ~ 5.95 times of those of plain pavement eoncrcte, both fatigue life can be described by two parameters WeiBull distribution. The study results in the paper provide the experimental basis for the application of basalt fiber in airport pavement engineering construction practice.
