摘要
以90号A级重交道路沥青作为基质沥青,在不同的试验条件下,基质沥青与不同类型的SBS调制改性沥青后进行分析,结果表明,双嵌段结构线型的S4302 SBS与此种沥青的相容性最好。在发育温度170℃、发育时间为4h、相容剂含量为4.0%,采用缓慢匀速方法加入稳定剂,改性沥青质量及效果最佳。
The matrix asphalt of grade 90#A heavy traffic asphalt was taken as the matrix asphalt. Under different test conditions, the matrix asphalt was analyzed with different types of SBS modified asphalt. The results showed that the double-block structure type S4302 SBS had the best compatibility with this kind of asphalt. At 170℃, 4 h, and 4.0% of compatibilizer, stabilizer was added by slow and uniform method, and the quality and effect of modified asphalt were the best.
