semi-rigid pavement base

But the principles of stress equivalence could accurately reflect the influence on the cement concrete pavement stress by the modulus and thickness of semi-rigid type base.

而以板底拉应力等效为指标的基层顶面当量回弹模量值能较为真实地反映基层刚度和厚度变化对板底拉应力的影响。

Firstly, the paper analysed the formation mechanism of the fatigue crack in asphalt pavement with semi-rigid base.

首先，论文分析了半刚性基层沥青路面疲劳裂缝的形成机理。

In China, the bituminous pavement with semi-rigid base is widely used in freeway, in which the early damage phenomenon is popular.

我国高速公路的路面广泛采用半刚性基层沥青路面，而这种路面出现早期破坏的现象比较普遍。
