| Abstract: | As foamed mixture light-weight soil embankment-fill technology has been of such characteristics as small unit weight, high mobility and self-standing after solidification. It has played an important role in solving such problems as the une- ven settlement and lateral displacement of new and old roadbeds as well as the stability of high-filling embankment in the process of road widening. On the basis of the extension project of Maba section of Jingzhu Expressway, the application of foamed mixture light-weight soil embankment-fill technology in the road widening process has been introduced so as to provide reference for similar projects. |
