摘　　要：鉴于目前低标号沥青已越来越成为国内研究的热点以及未来可能更广泛的应用,对四种国产AH-50沥青分别采用针入度和PG分级方法进行了试验检测,以分析目前AH-50沥青的现状,比较各沥青性能之间的差异,寻找各检测值与我国规范要求值之间的差距和存在的问题,从而提出我国关于沥青指标规定的适用性及其下一步进行改善的可能,为我国低标号沥青能够满足规范和工程应用的需要提供参考。Since the low grade asphalt has increasingly become a research hotspot at present and may be more widely applied in the future, Four kinds of domestic AH -50 asphalt had been test by penetration and PG classification method in this paper. The aim was to analyze the current status of AH -50 asphalt, compare the performance differences between them, and find the gap between each detected value and standard value in China and the existing problems. At last the applicability of China＇s asphalt specifications and the next step for the possible improvement were put forward, and the reference for China＇s low grade asphalt which met the specifications and engineering application was provided.
