The result shows it is feasible to measure and evaluate subgrade resilience modulus with PFWD.

同时,存在路基设计指标(回弹模量)与施工控制指标(压实度)不统一的问题。
At the same time, there is not uniform between subgrade design index (subgrade resilient modulus) and construction control index (compaction degree).

应用弹性层状理论,研究了不同等效方法对基层顶面当量回弹模量换算结果的影响。
The paper studied the calculation method of equivalent modulus of elasticity of foundation under principles of different equivalence by elastic multi-layer theory.
