摘要
为了考察SBS改性沥青生产过程中剪切时间、剪切温度、剪切速率对SBS改性沥青性能的影响，采用ESS090号沥青为基质沥青，4303SBS为改性剂进行试验研究。结果表明：剪切时间与SBS改性沥青的量有关，一般在45min至2h，剪切温度在170-175℃，剪切速率为6000r／min，此时，SBS改性沥青的路用性能指标最佳。
In order to investigate the effect of shearing time, shearing temperature, shearing rate on properties of SBS modified asphalt in the production process, the test was carried with No. 90 ESSO matrix asphalt and 4303 SBS modifier. The results showed that the shearing time related to the quality of SBS modified asphalt, generally varying from 45 minutes to 2 hours, shearing temperature was between 170 ℃ to 175℃, and the shearing rate was 6000 revolutions per minute. If so, the pavement performance index of SBS modified asphalt was best.
