摘要
为解决"两高土"利用的难题,文章以灌阳(永安关)至全州(凤凰)高速公路为研究对象,对利用高液限、高塑性指数黏土掺灰改良路基填筑施工技术进行了介绍,阐述了施工技术特点、适用范围、工艺流程及操作要点,并分析了"两高土"掺灰改良的经济、生态、环境效益。
In order to solve the use problem of＂two-high soil＂,with Guanyang（ Yonganguan）-Quanzhou（ Fenghuang） Expressway as research object,this article introduced the filling construction technology of clay ashmixing improved subgrade by using the high liquid limit and high plasticity index,described the construction technology characteristics,application scope,process flow and operating points,and analyzed the economic,ecological,and environmental benefits of＂two-high soil＂ash-mixing improvement.
