提高Ⅲ级湿陷性黄土路基的施工质量

Improvement of Construction Quality of Class ⅢCollapsible Loess Subgrade

路基为道路的基础,路基的强度和稳定性是保证路面强度和稳定性的基本条件,因此提高路基施工质量显得尤为关键。通过对湿陷性黄土路基施工过程中出现的质量缺陷的调查、详细分析出现质量缺陷的主要因素,从而制定相应对策以提高湿陷性黄土路基的施工质量。

The subgrade is the road foundation. The subgrade strength and stability are the basic conditions to guarantee the pavement strength and stability. Therefore, it is the special key to improve the subgrade construction quality. According to the investigation and detailed analysis of quality faults existing in the construction process of collapsible loess subgrade, the main factors of quality fault are found so as to formulate the relative measures taken for improving the construction quality of collapsible loess subgrade.
