铧本公路半刚性基层表面弯沉变化试验研究

Laboratorial study on the change of semirigid base's Surface deflection in Huajianzi-Benxi highway

在铧尖子至本溪二级公路上，对不同剂量的水泥、石灰稳定砂砾基层表面的不同龄期的弯沉跟踪测定，在此试验基础上，分析对比了水泥、石灰稳定砂砾基层的表面弯沉及其模量随龄期发展变化的规律。

Based on measuring the deflection of cement and lime stabilized gravel bases in different ages in Huajianzi-Benxi highway,this pater analyses the surface deflection of cement and lime stabilized gravel base and the change regulation of modulus following the age,and presentes a corresponding regression formula.
