Abstract

According to the subgrade construction in Nandeng expressway, this paper systematically elaborates the strength formation mechanism and construction techniques of lime stone as a kind of subgrade embankment material in processing expansive soil subgrade. It also illustrates the operation techniques of key working procedures, providing some guidance for the expressway construction in the expansive soil region.
