铧本公路半刚性基层表面弯沉试验研究

Hua-Ben Highway Semi-rigid Base Course Surface Deflection Experiment Study

在对铧尖子至本溪二级公路不同计量水泥、石灰稳定砂砾基层表面不同龄期弯沉的跟踪测定试验基础上 ,分析对比水泥、石灰稳定砂砾基层表面弯沉及其模量随龄期发展变化的规律 。

By tracing the deflection experiment of different cement lime stabilized sand gravel base course surface with different ages in the second class highway of Huajianzi-Benxi, the authors made comparison analysis of the surface deflection and its modulus development pattern along with its age. Regression formula and conclusions were got through the experiment.
