摘　　要：针对浇筑式沥青混凝土具有拌合温度高,沥青用量高的特点,以及浇筑式沥青混凝土在国内应用中出现的疲劳早期开裂病害,通过应变控制下的疲劳试验方法,分析研究了三种沥青结合料在不同拌合温度下浇筑式沥青混凝土疲劳特性,并确定了浇筑式沥青混凝土的配合比及拌合温度,对工程施工具有重要意义。The high mixing temperature and high asphalt content are the main characteristic of gussasphalt, which result in early cracking on the gussasphah pavement of domestic bridge. The fatigue characteristic was research due to three different asphalt under different mixing temperature of gussasphah with strain control. The mixing proportion and mixing temperature of gussasphah were fixed, it has important meaning for engineering construction.
