摘　　要：为了分析多重老化作用下温拌橡胶沥青的流变特性及微观性能,通过动态剪切流变试验、原子力显微镜试验、红外光谱试验和热重分析试验对Sasobit橡胶沥青和Evotherm橡胶沥青进行了研究。结果表明,Sasobit橡胶沥青的抗变形能力、抗老化性能、抗滑性能及热稳定性均优于Evotherm橡胶沥青。In order to study the rheological and microscopic properties of warm mixed rubber asphalt under multiple aging effects,Sasobit rubber asphalt and Evotherm rubber asphalt were investigated by dynamic shear rheology test,atomic force microscopy test,fourier transform infrared spectroscopy test and thermogravimetric analysis test.The results showed that Sasobit rubber asphalt was better than Evotherm rubber asphalt in terms of deformation resistance,aging resistance,slip resistance and thermal stability.
