摘　　要：SEAM是一种新型的沥青改性剂,同时也是一种沥青混合料添加剂,最近几年才引进我国并在天津进行首次应用,属于新材料、新工艺,因此有必要进行SEAM改性沥青的改性机理研究。通过一系列基准试验,比较分析了SEAM改性沥青的改性效果,结合相关化学理论知识,分析并总结了SEAM改性沥青的改性机理。SEAM is a new type asphalt modifier and also an additive used in asphalt mixture. Recent years it was introduced to our country and carry on in Tianjin apply for the first time, belong to the new material, the new craft, there{ore it has the necessity to carry on the research for the modified mechanism of SEAM modified asphalt. Through a series of datum experiment, comparatily analyze SEAM modified asphalts modified effect, with the union correlation chemistry theory; we have analyzed and summarized the SEAM modified asphalt modified mechanism.
