摘要
文章采用显微镜手段和DSC微观表征手段分别对干法和湿法工艺的北美岩沥青改性机理进行了研究,并对这两种不同工艺生产的沥青混合料性能进行了比较分析。研究结果表明:干法改性的沥青混合料有更好的路用性能。
By using the moans of microscope and DSC microscopic characterization, this article respectively studied the modification mechanism of American gilsonite under dry process and wet process,and conducted the comparative analysis for the properties of as- phalt mixture produced through these two different processes.The results showed that the asphalt mixtures modified by dry technology have better road performance.
