| 摘 要： | 通过考察老化过程中软化点的变化,建立以沥青软化点为参数的老化动力学模型,计算得到了有关动力学参数.实验以欢喜岭AH-90沥青为基质沥青,以SBS为改性剂,制备改性沥青,采用旋转薄膜烘箱试验,使改性沥青老化,然后通过掺入再生剂得到再生改性沥青,分别测改性沥青和再生改性沥青的软化点.实验表明,废旧SBS改性沥青可以通过添加...

| Abstract: | In this study,the kinetic parameters have been calculated to establish an aging dynamic model based on softening point.The theoretical value and the actual experimental data were well consistent.The modified asphalt was prepared by using Huanxiling AH-90 as base asphalt and SBS as modifier.Then rotating thin film oven test was conducted to make it aged.Regenerated modified asphalt was obtained by adding certain amount of self-made regenerant.The softening point was determined.The Test showed that waste SBS ... |
