摘要
由于沥青和改性剂的相互作用，改变了沥青的成分及结构，使沥青的流变性能发生了变化。采用DSR和BBR两种仪器，通过试验研究了温度与沥青的复数剪切模量、相位角、车辙因子、疲劳开裂因子、蠕变劲度及蠕变速率的关系，并分析了SBS改性剂对沥青流变性的改善效果。
Interaction between asphalt and modifier changes the composition and structure of asphalt as well as rhcologic behaviors. In this paper utilizing two instruments the relationships of temperature between complex shear modulus, phase angle, rut factors, fatigue cracking factor, creep stiffness tension and creep rate are studied. In the end the effect of SBS modifier in modifying rheologic properties of asphalt is analyzed.
