分析了玄武岩纤维的特性，并与常用纤维进行了比较。通过动态剪切流变试验和反复蠕变试验研究了玄武岩纤维增强沥青玛蹄脂的流变行为。结果表明，玄武岩纤维具有优异的增强性能，如高沥青吸收率、低吸水率、高拉伸强度、高弹性模量和高温稳定性等。纤维增强沥青玛蹄脂的车辙系数比普通沥青玛蹄脂高，高温下增强效果更加显着。沥青玛蹄脂的流变性能表现出不同温度和加载频率之间良好的线性关系。不同加载时间下沥青玛蹄脂的蠕变刚度模量可用幂函数表示。采用改进的Burgers模型来表征玄武岩纤维沥青玛蹄脂的流变行为，并对模型参数进行了估计。
The characters of basalt fiber are analyzed and compared with commonly used fibers. The rheological behaviors of the basalt fiber reinforced asphalt mastic are investigated by the dynamic shear rheological tests and the repeated creep tests. The results show that basalt fiber has excellent reinforced performances, such as high asphalt absorption ratio, low water absorption ratio, high tensile strength, high elastic modulus and high temperature stability. The rutting factor of the fiber reinforced asphalt mastic is higher than the plain asphalt mastic and the reinforced effects are more remarkable under high temperature. The rheological performances of the asphalt mastic demonstrate a good linear relationship between different temperature and loading frequency. The creep stiffness modulus of the asphalt mastic at different loading time can be expressed by power function. Improved Burgers model is used to represent the rheological behaviors of the asphalt mastic with basalt fiber and the model parameters are estimated.
