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。
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.
