摘要
基于聚合物改性沥青的原理和分类,详细总结了低温延度、测力延度、弗拉斯脆点、玻璃化转变温度和弯曲梁流变试验对于均质聚合物改性沥青的适用情况,评价了非均质聚合物改性沥青体系的研究现状,为后续聚合物改性沥青低温性能评价方法提供借鉴。
Based on the principle and classification of polymer modified asphalt,the applicability of evaluation methods to homogeneous polymer modified asphalt is summarized,such as low temperature ductility,force-ductility test,Fraass breaking point test,glass transition temperature and bending beam rheological test.Subsequently,the research status of heterogeneous polymer modified asphalt system is evaluated,which provide reference for further research on the evaluation method of polymer modified asphalt low temperature performance.
