摘要
本文采用薄片剪切流变仪研究了 SBS 改性沥青的流变特性。结果表明:经 SBS 改性的沥青,其流变模型由 Burgers 模型(四元件模型)转变为更为复杂的五元件模型,其瞬时弹性和推迟弹性均匀明显增大,而粘性显著减少。
This paper studies the rheological characteristics of SBS modified bitumen by using asheet shear rheometer.The results indicate that rheologic model of bitumen which is modified by SBSchanges from Burgers model(model of four elements)to more complicated model of five elements,both the instantaneous elasticity and retarded elasticity evidently increase and the viscosityremarkably decreases.
