摘要
比较了5种不同牌号乙烯/辛烯共聚物(POE)对沥青性能的改善效果,优选出最佳的POE改性剂;研究了不同加量的同种POE对沥青的改性效果;比较了相同加量下,POE、聚丙烯(PP)、聚乙烯(PE)改性沥青的性能指标。结果表明:POE能显著改善改性沥青的针入度、软化点和耐热性能等,较PP和PE对沥青的改性效果更为显著。
This paper studied modification effects of 5 kinds of polyolefin elastomer （POE） and different dosages of the same kind of POE on asphalt. The best POE was determined. The performances of asphalt modified by POE, PP and PE with the same amount were compared. The results showed that POE could significantly improve the penetration, softening point and heat resistance of asphalt, and its modification effect was better than that of PP and PE.
