摘要
本文阐述了FWD在检测路基路面材料动弹性模量中的应用,并计算分析了均质体与层状体两种情况下半圆和双圆荷载弯沉盆的关系,介绍了路基、路面强度的无损快速检测与评定的经验。
The evaluation of the dynamic elastic modulus of subgrade and flexible pavement by FWD method is presented in this paper.The different deflection basins on the homogeneous material and the layered materials under single-wheeled and dual-wheeled loading respectively are compared and analyzed based on field observations in order to provide a quick and non-destructive method for evaluating the strength of the subgrade and fle- xible pavement.
