分别对掺入PR抗车辙添加剂、TLA湖沥青和SEAM的沥青混合料进行劈裂疲劳对比试验和老化后的疲劳试验,对比分析其疲劳性能的优劣。分析了添加抗车辙剂的沥青混合料疲劳作用机理。解释了添加不同抗车辙剂后,沥青混合料的疲劳性能形成差异的原因。
The asphalt mixture mixed with PR anti-rutting additive, TLA lake asphalt and SEAM was compared with the splitting fatigue test and the aging fatigue test, and the fatigue performance was compared and analyzed. The fatigue mechanism of asphalt mixture added with anti-rutting agent was analyzed. Explains the reasons for the differences in the fatigue properties of asphalt mixtures after adding different anti-rutting agents.
