【摘要】 针对聚乙烯改性沥青高温储存不稳定的缺点,采用等密度法研完了炭黑添加量对聚乙烯改性沥青常规性能及稳定性的影响,并对改性沥青的结构进行了分析,发现聚乙烯中一定含量的炭黑可获得储存稳定的改性沥青,并且对改性沥青性能影响不大。更多还原

【Abstract】 Polyethylene modified asphalt is unstable during hot storage. The effect of carbon black on the classical and storage properties was investigated; the structure of the modified asphalt was also investigated. The result showed that a certain content of carbon black can give stable polyethylene modified asphalt,and have little effect on classical property.更多还原
