利用LDHs对沥青进行熔融共混改性，并利用动态剪切流变仪（DSR）研究了LDHs改性沥青的粘弹性。蠕变试验用于评估粘弹性行为。实验结果表明，由于LDHs的添加，改性沥青的粘弹性性能优于原始沥青。因此，LDHs将成为沥青中使用的改性剂的替代品，以提高沥青路面使用过程中的抗紫外线老化性能。
We applied LDHs to modify the bitumen by melt blending, and studied the viscoelasticity of LDHs modified bitumen by means of dynamic shear rheometer (DSR). The creep test was used to evaluate the viscoelastic behavior. The experimental results indicated that, due to the addition of the LDHs, the viscoelastic properties of modified bitumen were superior to those of pristine bitumen. Therefore, the LDHs would be an alternative to modifiers used in the bitumen to improve the UV-aging resistance during the service of asphalt pavement.
