摘要
以中石化金陵炼化厂生产的90#A级沥青为基质沥青,以岳阳石化厂生产的SBS791-H为改性剂,一种糠醛抽出油作为相容剂制备了改性沥青,研究了不同糠醛抽出油添加量下,改性沥青在RTFOT老化前后四组分和性能的变化情况,探讨了糠醛抽出油对SBS改性沥青的作用机理以及适宜添加量。
The asphalts modified by SBS as the basic asphalts,which were made from A grade 90# asphalt made by Jinling Petrochemical Corporation of Sinopec,SBS 791-H as modifier,made by Yueyang Petrochemical Corporation of Sinopec,and furfural extract oil as compatibilizer,the modified asphalts was made as the basic asphalts,which four components and performance of the modified asphalt fore and after RTFOT aged test were studied.The mechanism of action and proper additive ratio of furfural extract oil to asphalt modified by SBS were researched.
