摘　　要：采用乳化SBS改性沥青和在乳化沥青中掺入SBR胶乳两种方式,研究了改性方式对乳化沥青性能的影响,试验结果表明:随着改性剂掺量的增加乳化沥青的软化点、延度和恩格拉黏度增大,针入度降低,且SBS和SBR作用效果有所不同;乳化沥青的平均粒径随着SBS掺量增加而增大,而SBR的掺入对平均粒径的影响较小。We selected SBS modified asphalt emulsion and emulsion asphalt incorporated SBR latex, to study the effect of different modification methods on the performance of asphah emulsion. The test resuhs show that the sogening point, ductility and Engela viscosity increase as modifier increasing, and the penetration reduces ; but SBS and SBR took different effect. The average particle diameter of emulsified asphalt： increases as SBS content increasing, yet SBR has less impact.
