Abstract:Researching on the characteristics of expansion and shrinkage of expansive soil modified by lime,the increment of strength of lime treat soil.The relation of ratio of added lime and unconfined compressive strength is obtained.The idea that during the construction of subegrade through expansive-soil area different optimal ratios of added lime should be ascertained respectively in different segments is proposed.It will be beneficial to subgrade consruction.
