摘　　要：研究了路孚8000沥青改性剂的各项性能。对路孚8000不同掺量下的沥青胶结料进行了基本性能试验,并对掺加路孚8000后的改性沥青混合料进行了高温车辙、低温弯曲、冻融劈裂和疲劳试验。结果表明:路孚8000沥青改性剂可以改善沥青的感温性和抵抗荷载变形的能力;加入路孚8000改性剂后,沥青混合料高温稳定性、低温抗裂性、水稳定性及抗疲劳性等性能军得到了增强,尤其是高温抗车辙性能得到了较大的提高。Performances of asphalt modified by LF8000 were tested. The basic tests such as the rutting tests, low temperature bend tests, frost thawing split tests and fatigue tests were dnne. The results showed that LF8000 could enhance the temperature susceptibility and the ability to resist the force deformation. After being added with LF8000, every performance of asphah mixture had been improved especially its stability of high temperature.
