semi-rigid pavement concrete

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。

The new cement concrete road pavement, glass fiber grid should be placed between semi-rigid base and rigid concrete seal.

对新建水泥混凝土道路路面，玻纤格栅应置于半刚性基层与刚性水泥混凝土封层之间。

The understanding of semi-rigid base is still not widely accepted. The erosion and pumping have already affected the application of cement concrete pavement on expressways.

对半刚性基层的认识仍然得不到统一，而冲刷唧泥已经影响到水泥路面在高速公路上的推广应用。
