摘要
Abstract
In this paper,the expansive soil of a project in Mengzi City,Honghe was taken as the research object,and the road characteristics of plain soil,lime,fly ash and cement improved expansive soil were studied.The results show that the maximum dry density of lime,fly ash and cement improved expansive soil gradually decreases with the increase of content,the optimal moisture content of lime and cement improved expansive soil increases with the increase of content,and the optimal moisture content of fly ash improved expansive soil decreases with the increase of content.The swelling amount of the three improved expansive soils decreased with the increase of the incorporation ratio,and the CBR value was the opposite.In terms of increasing the CBR value,cement has a better effect,followed by lime,and fly ash has the worst effect.关键词
