| 摘 要： | 研究了Sasobit（R）掺量对其改性沥青在不同温度下的物理和流变特性的影响。选择PG58-22沥青为基质沥青,然后掺加1%,2%,2.5%,3%和4%的Sasobit（R）进行改性。采用SHRP试验方法对改性沥青在高温、中温及低温下的特性进行评估。结果表明,Sasobit能够改善沥青的高温性能,而中温及低温性能并没有得到显著的改善。Sasobit（R）掺量对沥青粘度的影响结果表明,增加Sasobit（R）的掺量可以降低沥青的粘度。

| Abstract: | Studied Sasobit dosage effect on the physical and rheological properties of modified asphalt at different temperatures of. Select PG58 - 22 asphalt asphalt, then mixing 1%, 2% , 2.5% , 3% and 4% Sasobit modified. SHRP test methods using modified asphalt at high temperatures,the temperature characteristics and low temperature evaluation. The results show that,Sasobit can improve the high temperature performance of asphalt, while the temperature and low temperature performance is not significantly improved. Sasobit dosage affect the results show that the viscosity of the bitumen to increase the dosage Sasobit can reduce the viscosity of bitumen. |
