SBS/炭黑共混物改性沥青高温贮存稳定性研究

Study on hot storage stability of SBS/carbon black blend modified asphalt

SBS改性沥青在高等级公路路面建设中发挥着重要作用,但其高温贮存不稳定一直是限制其发展的障碍。主要研究了SBS?炭黑复合改性沥青的结构与性能,特别是高温贮存稳定性。通过改变SBS?CB共混物中二者的比例,制备出了高温贮存稳定的改性沥青。

SBS modified asphalt has played an important role in the rapid development of highway. However, SBS modified asphalt is prone to unstable during hot storage, which present an obstacle to its development. SBS/CB blend modified asphalt and its high- temperature storage stability were studied in this paper. By changing the ratio of SBS to CB, the modified asphalt with high-temperature storage stability was prepared?
