Abstract: As a ground treatment technology, the soil solidification method has been widely used in the road and the embankment construction. In this study, the small-scale direct shear tests, the unconfined compression tests and the CBR tests were carried out on the cured waste soil mixed with different agents. The results showed that the strength of all solidified soil samples increased with the increase of age, and the soil strength strengthened with the KZJ-F type agent increased most rapidly. Field tests were also performed in this study. The KZJ-F type agent was used to treat the in-situ soil, and vane plate shear tests and plate loading tests were performed at different depths. The results show that the shear strength of the solidified soil was greater than than 150kpa at all depths, and the ultimate bearing capacity was greater than 350kpa at the age of 7d to 28d, which fully met the engineering requirements.
