采用动态剪切流变仪、弯曲梁流变仪对国创90号，SK 90号和 Shell 90号3种基质沥青制备的橡胶改性沥青的常规技术性能、高低温流变性能、抗老化性能和存储稳定性进行研究。结果表明，SK 90号橡胶改性沥青的常规技术性能优于其他两种橡胶改性沥青。64℃时 SK 90号橡胶改性沥青的高温抗变形性能最优，但其对温度的敏感性更大，随着温度继续升高，其高温性能劣于国创90号橡胶改性沥青和Shell 90号橡胶改性沥青。国创90号、SK 90号和Shell 90号橡胶改性沥青的高温分级分别为76，82和82℃，而低温分级均为－28℃。但劲度模量和蠕变速率的变化趋势表明，低温抗裂能力由强到弱依次为 SK 90号橡胶改性沥青...

Dynamic shear rheometer and bending beam rheometer were used to research rheological properties,anti-aging performances and storage stabilities of the three rubber modified asphalt.The results indicate that conventional indexes of SK90# rubber modified asphalt are better than the other two asphalts.When the temperature is 64 ℃,the high temperature deformation resistance of SK90#rubber modified asphalt is the optimal,while its high-temperature performance becomes worse than the other two asphalts as temperature rises.The high-temperature PG deg...
