摘要
介绍改性沥青相容性的基本理论,研究了热塑性弹性体SBS的结构和用量、沥青的种类及化学稳定剂对SBS改性沥青相容稳定性的影响。结果表明线型SBS较星型SBS与沥青有更好的相容性;芳香分及软沥青质含量高的沥青与SBS的相容性较好;化学稳定剂对SBS改性沥青的相容稳定性有很好的改善作用。
The basic theory of interblend stability of modified asphalt is introducd in this paper.The influence of the structure and dose of thermoelastic SBS kinds and chemical stability of asphalt on the interblend stability of modified asphalt with SBS was studied.The result is the linear SBS has better interblend ability than the star-like one.The chemical stabilizing agent contributes to a better interblend stability of SBS modified asphalt.The higher con-tent of aromatic phenol has better interblend ability with SBS.
