中文摘要：

为研究层间状态与上下层压实度差异对整体大厚度水泥稳定碎石基层耐久性能包括干缩、温缩和抗冲刷性能的影响，通过室内模拟不同层间状态和上下层不同压实度差异的方法进行研究。结果表明：层间状态与上下层压实度差异对整体大厚度水泥稳定碎石基层的干缩、温缩和抗冲刷性能具有较大影响；比较而言，上下层压实度差异对干缩性能影响更大，而层间状态对抗冲刷性能影响更明显，层间状态和上下层压实度差异对其温缩性能均有明显影响；提高层问状态的连续性、降低上下层压实度差异可提高整体大厚度水泥稳定碎石基层的耐久性能。

英文摘要：

For studying layer state and compactness difference about upper layer and lower layer had an influ- ence on durability of entirety large thickness cement stabilized macadam including drying shrinkage perform- ance, temperature shrinkage performance and anti-erosion performance. Research was processed by simulating layer state and compactness difference about upper layer and lower layer in the laboratory; The results showed that layer state and compactness difference about upper layer and lower layer had great influence on entirety large thickness cement stabilized macadam base drying shrinkage performance, temperature shrinkage perform- ance and anti-erosion performance; comparatively speaking, compactness difference about upper layer and lower layer had greater influence on drying shrinkage performance, but layer state had obvious influence on an- ti-erosion performance, both of them had obvious influence on temperature shrinkage performance; improving the layer state continuity and decreasing compactness difference about upper layer and lower layer can enhance entirety large thickness cement stabilized macadam base durability performance.
