摘　　要：对新型改性剂路孚8000进行了路用性能研究。进行了不同路孚8000掺量的沥青胶结料的针入度试验、软化点试验,对加入路孚8000改性剂后的沥青混合料进行了车辙试验、弯曲破坏试验、疲劳试验和冻融劈裂试验,并对基质沥青混合料、SBS改性沥青混合料和加入路孚8000的沥青混合料进行了模糊评判分析和经济分析。结果表明,路孚8000对于沥青胶结料的感温性、高温性能有较大的提高;加入路孚8000后,沥青混合料的各项路用性能都得到了较大程度的提高,尤其是高温稳定性得到了极大的提高;并且,路孚8000具有较好的经济性。因此,路孚8000适用于高温地区重交通高等级公路沥青路面,具有优良的性价比。Systemic researches were done to the new type additive LF8000.Some tests including penetration and softening point on asphalt binders modified with new type additive LF8000 were presented. Rutting test, fatigue test, beam bending test and moisture damage test were carried out on asphalt mixtures with LF8000. All the tests indicated that LF8000 can improve high temperature stability, moisture stability, low temperature performance and fatigue life, especially the high temperature stability. Fuzzy mathematic judgement and economic analysis were done to control asphalt mixture, SBS modified asphalt mixture and Lufu8000 modified asphah mixture. The results indicated that Lufu8000 can be used in areas with high temperature and heavy traffic load, and LF8000 is cost effective.
