摘要
采用流变学理论分析改性沥青的高温性能,利用Burgers模型将沥青与混合料的粘性部分与弹性部分分开,通过模型参数变化评价改性剂对沥青及混合料的高温稳定性的影响,为其进一步的研究探讨提供了理论基础。
Utilizing theory of rheology the high-temperature properties of modified asphalt are analyzed. Based upon Burgers model the viscous part and elastic part of asphalt and mixture are separated. Through analysis of the change of model parameters the influences of modifier on stability of asphalt and mixture at high temperature are evaluated, which provide theoretical references for further study.
