摘　　要：从室内试验和理论分析两方面研究具有碎石上基层的半刚性沥青路面非线性特性和碎石上基层模量合理取值 ,研究结果表明碎石上基层具有比传统柔性基层高得多的弹性模量 。Through laboratory research and theory analysis, the nonlinear property of semi-rigid asphalt pavement with granular (upper) base is studied and the modulus values of granular (upper) base is suggested. It is proved that the modulus of traditional flexible base is further smaller than granular (upper) base. In addition, the nonlinear property of granular (upper) base is advantageous to the fatigue of pavement.

关 键 词：碎石上基层 半刚性沥青路面 非线性 模量
