| 摘 要： | 通过测力延度试验分别对SBS、SBR、EVA、PE四种改性沥青的低温拉伸性能进行了测试分析，研究了各种聚合物的种类、掺量、基质沥青、热老化等因素对聚合物改性沥青测力延度性能的影响。试验结果表明，测力延度试验可以比较全面的反映改性沥青的低温拉伸性能，是评价改性沥青低温性能的简单有效的方法。

| Abstract: | The low temperature tension performances of SBS, SBR, EVA, PE polymer modified asphalts were studied by force ductility tests. The effects of polymer characteristic, polymer content,based asphalt properties and heat aging on force ductility performances of polymer modified asphalts were investigated. Test results indicate the force ductility test is a simple and effective mean of characterization of low temperature tension properties of polymer modified asphalt. |
