| 摘 要： | 与基质沥青相比,SBS改性沥青的低温性能更加复杂,因此,选用更合适的评价指标是必要的。采用测力延度试验,本文分析了不同SBS改性沥青在不同温度,不同改性剂掺量下的性能变化特点。选用柔量D/FZ,应力差值比(F1-FZ)/(F0-FZ)和能量比W2/W1作为评价指标并加以阐述,以更有效地评价SBS改性沥青的低温性能。

| Abstract: | Compared with unmodified asphalt,the low-temperature performances of modified asphalt are more complicated,therefore it is necessary to choose fitter appraisal indexes.Through lots of force ductility tests,the tensile performances of the different SBS modified asphalts in different temperatures are analyzed.Compliance D/F_Z,stress difference ratio(F_1-F_Z)/(F_0-F_Z)and energy-ratio W_2/W_1 are selected to appraise more effectively the low-temperature performance of SBS modified asphalt. |
