| Abstract: | A mass of sub-clay distributes in the flood retarding basin of S250 Highway. The sub-clay which is used as embankment filler must be improved, three methods such as adding cement, cement-fly ash and cement-lime are adopted to improve the sub-clay. Based on unconfined compressive strength tests, influence of compactness, type of stabilizer and dosage of stabilizer on the compressive strength of improved soils is analyzed and then the strategies of improving sub-clay and embankment filling is discussed. |
| Keywords: | embankment embankment filler silty clay improved soil unconfined compressive＇ str6ngth |
