摘要: 采用添加硬沥青、 石油树脂和助剂的方法制备了I - C级克拉玛依S B S改性沥青, 考察了硬沥青、 石油树脂以及助剂对S B S改性沥青软化点、 针入度以及储存稳定性的影响。结果表明, 当改性剂S B S质量分数为4%、 硬沥青质量分数为3%、 石油树脂质量分数为3%、 助剂质量分数为2%时, S B S改性克拉玛依沥青的软化点为5 5. 6℃,针入度为6 0. 7( 0. 1mm) , 5℃时延度达到3 1. 2c m , 在1 6 3℃的温度下储存4 8h时, 上、 下层软化点之差为1. 2℃,符合I - C级改性沥青标准要求。

Abstract: Karamay SBS modified asphalt was prepared to meet the requirements of the specifications for SBS (IC) asphalt by adding hard asphalt, petroleum resin and additives. The effects of hard asphalt, petroleum resin and additives on the softening point, penetration and storage stability of SBS modified asphalt were investigated. When the dosage of modifier SBS, hard asphalt, petroleum resin and the additives were 5%, 3%, 3%, and 2% respectively, SBS modified Karamay asphalt's softening point was 55.6 ℃, the penetration was 60.7 (0.1 mm), ductility at 5 ℃ was 31.2 cm, and the difference of softening point from the top and the bottom of storage tube was 1.2 after 48 h of storage at 163 ℃.The properties of said modified asphalt met the requirements of the specifications for SBS (IC) asphalt.

Key words: SBS, Modified asphalt, Hard asphalt, Petroleum resin, Additive
