玄武岩纤维沥青混合料的冻融损伤演化规律
|
摘要
为研究寒区玄武岩纤维改性沥青路面的抗冻融性能,本文借助可靠度和损伤理论,建立了玄武岩纤维沥青混合料冻融损伤演化的三维模型,并讨论了参数的实际意义。根据冻融循环下的混合料劈裂强度和劲度模量试验结果,建立各自的损伤演化模型,采用增强因子k来评价掺加玄武岩纤维对沥青混合料抗冻融性能的增强效果。结果表明:掺加玄武岩纤维后,沥青混合料的劈裂强度和劲度模量对冻融损伤的抵抗能力均有所提高;玄武岩纤维沥青混合料受到均匀的冻融损伤;劈裂强度受冻融循环的影响更为显著,可用于预估冻融损伤残余寿命。
To investigate the freeze-thaw resistance of basalt fiber-modified asphalt pavement in cold regions,this study established a three-dimensional model of freeze-thaw damage evolution of basalt fiber-modified asphalt mixture by using reliability and damage theory. The corresponding algorithm was also proposed to analyze model parameters.According to the test results of splitting tensile strength and stiffness modulus of the ordinary asphalt mixture and basalt fiber-modified asphalt mixture under freeze-thaw cycles,damage evolution models were established to analyze the influence of basalt fiber on the model parameters. The enhancement factor k was used to evaluate the effect of additive basalt fiber on the freeze-thaw resistance of the asphalt mixture. Results indicate that the addition of basalt fiber increases the splitting tensile strength and stiffness modulus of the asphalt mixture and improves its freeze-thaw resistance. The freeze-thaw damage of the basalt fiber-modified asphalt mixture is uniform. The performance of splitting tensile strength is more obvious than the stiffness modulus. Thus,this method can be applied to prediction of freeze-thaw damage life of basalt fiber-modified asphalt mixture.
