摘　　要：对一种新型沥青混凝土添加剂(路孚8000)进行了研究。通过不同掺量下沥青胶结料的针入度、软化点、稠度、延度及测力延度、直接拉伸、弯曲梁蠕变和弹性恢复试验,表明该添加剂可以改善沥青的感温性和抵抗荷载变形的能力。对改性沥青混合料进行高温车辙、低温弯曲、冻融劈裂和疲劳试验,表明其各项性能尤其是高温抗车辙性能均得到了较大的提高。This article researched the performance of a new type of asphalt concrete additive named LF80 00 . The penetration, softening point, ductility＆force-ductility, DTT, BBR and flexibility resume tests with different amount of LF8000 were done, which showed that LF8000 could enhance the temperature susceptibility and the ability to resist the force deformation. Through the high-temp running tests, low-temp bending tests, frost thawing split tests and fatigue tests, it indicates that the performance of the asphalt mixture modified by LF8000 had been improved highly.
