摘　　要：沥青稳定碎石基层可以显著减少沥青路面一些早期损害,通过采用ABAQUS三维有限元方法,对设置沥青稳定碎石基层的沥青路面结构进行力学性能分析,分析路面结构应力和应变的影响。从结构角度提出对沥青稳定碎石基层材料的性能的要求,并且对设置排水基层的半刚性基层沥青路面结构设计提出相应建议。Asphalt stabilized gravel base course can significantly reduces the number of early damage to asphalt pavement.Through using three-dimensional finite element method,the mechanical performance of asphalt pavement structure added asphalt stabilized gravel base is analyzed,and stress and strain of asphalt pavement structure is also analyzed.Performance requirement of drainage base materials is proposed from the point of structural,and the structure design recommendation of semi-rigid base of the asphalt pavement added asphalt stabilized gravel base course is put forward

关 键 词：路面结构 沥青稳定碎石基层 力学特性
