摘要
SBR胶粉对沥青延度提高比SBR胶乳明显,但对软化点改善效果不及SBR胶乳,应用中可以复配SBS以满足较高软化点要求。添加抗氧化剂可以提高SBR改性沥青的老化后性能。静止热储存时SBR改性沥青延度将下降。
softening point Compared wi was higher o enhance the softening point. FOT. Still hot storage led to th the asphalt modified by SBR latex, the ductibility was poorer and the f the asphalt modified by powdered SBR. The addition of SBS was able to The addition of anti-oxidant was able to enhance the ductibility after RTFOT. Still hot storage led to the reduction of ductibility.
