摘要
Sasobit与Sasowam改性剂是两种新型的温拌沥青改性剂,研究结果表明,两者均能有效降低沥青运动粘度,并提高沥青高温稳定性,改性效果良好,在推荐掺量范围内,Sasowam改性效果较Sasobit好。但两种改性剂的改性效果均受其与基质沥青的配伍性影响,使用时还需进行混合料试验确定施工温度。
Sasowam and Sasobit are two new kind of warm mix asphalt modifying agents, which could reduce as phalt＇ s kinematic viscosity, increase asphalt＇s high temperature stability, and in the range of recommended con sumption, Sasowam is better than Sasobit. Their modification effects could be influenced by the compatibility of it and asphalt, and mixture tests should be done for selecting construction temperature.
