Experimental Study on Lightweight Subgrade Fill Mixed with Dredged Silt and Waste EPS Beads

For the purpose of effective waste disposal and widening the source of subgrade fill, the curing agent of “gypsum soda residue” was used to make the research and development on the key technology of mixing proportion and construction process for preparation of lightweight soil. The new technology and process for mixing lightweight soil with dredged silt and EPS grain are put forward. The result shows that this new kind of soil is light, high-strengthened, economic and friendly to environment; thus it has good performance in enhancement of waste disposal, and reduction of natural earth excavation, land occupation and environmental contamination.
