摘　　要：基于株洲市机场大道一期工程二标段全风化及强风化花岗岩土质路基,研究了全风化及强风化花岗岩的矿物成分、液塑性指标及加州承载比(C B R)值等,得出了全风化及强风化花岗岩不宜直接作为路基填料,必须经过改良才能使用的结论。提出了用石灰改良全风化及强风化花岗岩的处治方案,并进行了配合比设计,且对施工工艺提出了要求。Based on the whole and strong weathered granite subgrade of the two section of the first project on Zhuzhou city airport road, studied the soil mineral composition, fluid plasticity index and CBR（Califomia bearing ratio） value of the whole and strong weathered granite, and concluded that the whole and strong weathered granite was not suitable for the subgrade filling and it must be improved to use. Put forward the lime improved treatment scheme to solve the problem of whole and strong weathered granite, designed the mixture ratio and presented the construction technology requirements.
