| 摘 要： | 采用高速剪切工艺制备了ＳＢＳ改性沥青，并应用凝胶渗透色谱法测试了ＳＢＳ改性沥青在不同发育时间下的分子量分布特征，探讨了ＳＢＳ改性沥青的机理，提出适合于ＳＢＳ改性沥青的工艺条件是高温剪切后低温充分发育的二阶段工艺。 |
| 关 键 词： | 凝胶渗透色谱法 改性沥青 高速剪切 改性机理 |

| Abstract: | In this paper by Gel Permeation Chromatography(GPC) characteristic of the molecular weight distribution is determined, and the SBS(Styrene-Butadiene-Styrene) modified mechanism is probed. Through systemic tests the optimal technology conditions of SBS modified asphalt is defined, that is, by following steps shearing SBS by high-speed shear equipment, and then, developing in lower temperature. |
| Keywords: | Gel Permeation Chromatography modified asphalt high-speed shear modified mechanism |
