将粘弹性相行为引入SBS改性沥青中以解释相形态演化，其粘弹性模式最近由Zhu和Kringos（2015）提出。通过形貌演化和粘弹性变化研究了动态不对称性和组分不对称性的耦合效应。结果表明，SBS与沥青质之间对轻组分吸收的竞争对SBS/沥青共混物相分离过程中的形态形成起着关键作用。(C)2015爱思唯尔有限公司版权所有。
Viscoelastic phase behavior is introduced into SBS modified bitumen for the interpretation of phase morphology evolution, whose viscoelastic mode is proposed very recently by Zhu and Kringos (2015). The coupling effects of dynamic asymmetry and compositional asymmetry are investigated by morphology evolution and viscoelasticity change. It is found that the competition between SBS and asphaltenes to absorb light components plays a key role in morphology formation during phase separation of SBS/bitumen blends. (C) 2015 Elsevier Ltd.
