Abstract This study is aimed to investigate the effect of polymer nanocomposite of Ultra-high-molecular-weight polyethylene and Nanoclay on rheological behavior of asphalt binder. Therefore, the dynamic shear rheometer and bending beam rheometer were used to determine the characteristics of control and modified asphalt binder at moderate, high and low temperatures. The results indicate that the use of nanocomposite, especially in the amount of 4% (by weight of asphalt binder), increases the resistance to rutting fatigue cracking. Also, Modified asphalt binder at low temperatures based on the two creep stiffness parameter and m-value has a better performance than control asphalt binder.

UHMWPE/纳米粘土对改性沥青结合料流变性能的影响

摘要 本研究旨在研究超高分子量聚乙烯和纳米粘土的聚合物纳米复合材料对沥青结合料流变行为的影响。因此，采用动态剪切流变仪和弯曲梁流变仪测定中、高、低温下控制和改性沥青结合料的特性。结果表明，纳米复合材料的使用，尤其是用量为 4%（以沥青粘合剂的重量计），提高了抗车辙疲劳开裂的能力。此外，基于两个蠕变刚度参数和 m 值的低温改性沥青结合料比对照沥青结合料具有更好的性能。
