摘　　要：改性沥青的流变特性较为复杂,简单的常规试验方法不能很好地测出其特性.文中通过对基质沥青、SBS改性沥青、APAO和SBR改性沥青胶结料进行大量测力延度试验,分析了基质沥青、改性沥青的拉伸特性,证明了测力延度试验是评价改性沥青胶结料性能的一种有效方法,它可以作为一种简单、快捷判定沥青胶结料种类的方法,并有助于选择出性能优良的沥青胶结料.As the normal testing method can not correctly measure the complex rheologic characteristics of modified asphalt, a great number of force-ductility tests were performed to analyze the tension characteristics of the original asphalt binder, SBS-modified asphalt binder, APAO-modified asphalt binder and SBR-modified asphalt binder. It is proved that the force-ductility test is an effective method to evaluate the performance of modified asphalt binder, as well as a simple and expedient method to identify the type of asphalt binder. And it also helps a lot in selecting asphalt binder with excellent performance.
