| 摘 要： | 采用针入度、软化点、延度和弹性恢复等常规性能试验以及粘度、DSR和BBR等SHRP性能试验对SBS改性沥青的性能老化规律进行了系统评价,结果表明,SBS改性沥青的老化包含了两个部分,基质沥青的老化和SBS改性剂的劣化,但是二者的相互保护作用也有效的提高了SBS改性沥青的抗老化性能。

| Abstract: | The paper has the systematic evaluation on the performance aging law of SBS modified asphalt by adopting the regular performance tests by adopting the penetration,the softening points,the ductility and the elastic recovery,and the SHRP performance experiments of the viscosity,DSR and BBR,and proves by the results the aging of SBS modified asphalt consists of two parts,that is,the aging of the base asphalt and the deterioration of the SBS modifier,but the mutual protection of the two can improve the anti-aging performance of SBS modified asphalt. |
