【摘要】 沥青结合料的质量好坏直接影响到沥青路面的使用性能及使用寿命,通过对8种沥青结合料经PTFO老化前后进行动态剪切流变试验测定的车辙因子评价沥青结合料的高温性能,车辙因子越大,沥青结合料的高温性能就越好。更多还原

【Abstract】 Quality of asphalt binder directly influences the service performance and service life of asphalt pavement.By means of rut divisors determined by dynamic shear detrusion test of 8 kinds of asphalt binders around PTFO aging,the paper assesses the asphalt binder behaviors at high temperature.The rut divisor is the more,the behavior of asphalt binder at high temperature is the better.更多还原
