| 摘 要： | 采用荧光显微镜和沥青基本性能测试分析的方法,研究了糠醛抽出油对SBS改性沥青性能的影响。结果表明,糠醛抽出油的掺入能显著改善SBS在沥青中的分散性,使得SBS溶胀得更为充分,提高了改性沥青的抗老化性能和高温存储稳定性。随着糠醛抽出油掺量的增加,针入度逐渐升高,软化点和延度先升高后下降。

| Abstract: | The influence of furfural extract oil on property of SBS modified asphalt （SMA） was investigated based on fluorescence microscope and basic properties measurement. The results suggested that the dispersity of SBS in asphalt was notably improved by the addition of furfural extract oil, which enhanced the age- ing resistance and the storage stability at high temperatures of modified asphalt, due to the more sufficient swelling of SBS. Moreover, with the adding of the furfural extract oil to SMA, the penetration of SMA gradually increased, while the softening point and the ductility exhibited the variation tendency of decline after an obvious increase. |
