| 摘 要： | 级配碎石材料模量低，具有非线性的应力应变特性。将级配碎石层放置于半刚性底基层沥青路面后结构的受力形式发生了改变。通过使用KENLAYER程序对这一结构进行了受力计算。分析了结构的破坏类型并对结构的设计指标以及合理的结构设置提出了建议。

| Abstract: | It is generally known that unbound aggregate material used for base courses have a non- linear elastic stress-strain behavior. After unbound aggregate being settled in the semi-rigid pavement, there are great changes in structural stress distribution and form of structural default. Main form of structural default is found in semi-rigid asphalt pavement with unbound aggregate upper base through contrasting. And it suggests control index and proper structural design. |
