中文摘要：
针对刚柔复合式路面层间沥青材料的特点和现有研究不够系统的问题，运用旋转流变仪对4种层间沥青材料进行了高温剪切性能和粘度测试，并进行了动态力学温度扫描和剪切疲劳试验。试验结果表明：作为层间粘结材料，橡胶沥青和SBS改性沥青的性能明显要优于基质沥青，其高温性能、力学性能、粘度和疲劳性能均优于A-50和A-70；改性沥青用作层间材料时，SBS改性剂需确定适宜的基质沥青以提高SBS改性剂与基质沥青的相容性，以便获得良好的疲劳性能；层间为洒布式结构时，推荐SBS改性沥青为层间材料，为铺装式结构时，建议层间采用橡胶沥青。
英文摘要：
Focusing on the characteristics and unsystematic existing studies of interlaminar asphalt material of rigid-flexible composite pavement, the high-temperature shear properties and viscosities of 4 kinds of interlaminar asphalt material are tested using rotational rheometer, and the dynamic mechanical temperature scanning and shear fatigue test are also conducted. The test results indicate that （ 1 ） as interlaminar bonding material, the performance of asphalt rubber and SBS modified asphalt are significantly better than that of base asphalt, the high temperature performance, mechanical property, viscosity and fatigue property of the first two kinds of asphalt are superior to A-50 and A-70; （2） when modified asphalt is used as interlaminar material, the appropriate base asphalt should be determined for SBS modifying agent for improving the compatibility of SBS modifying agent and base asphalt to obtain good fatigue property ; （3） it is recommended to use SBS modified asphalt for interlaminar asphalt material when the interlaminar structure is spraying type, and to use asphalt rubber when the interlaminar structure is pavement type.
