Abstract Modified carboxymethyl cellulose sodium exhibits the strong dialysis cementation and adsorption behavior on the surface of soils and rocks. When the slope surface is covered with a layer of soil mixed with the modified CMC of an appropriate concentration，a protective soil layer against the erosion with the thickness of 12–15 cm is created. Silty sand samples taken from the surface of excavation slopes alongside a highway were mixed with the modified CMC of different concentrations. The shear strength tests，the disintegration tests，the permeability tests and the tests under freezing-thawing cycles were carried out to obtain the basic physical and mechanical characteristics of the mixture. The test results show that，with the increase of the concentration of the modified CMC，the hydraulic stability and shear resistance increase and the permeability decreases. When the soil is mixed with 1.1% of the modified CMC，the disintegration phenomenon disappears，and the cohesion and the friction angle are respectively，1，2 and 0.8 times greater than the samples without the modified CMC. The permeability coefficient changes from 2.17×10－4 cm/s to 1.0×10－5 cm/s，and the loss of the strength due to the freezing-thawing is less than 25%. The erosion gully of 13 cm wide and 9.0 cm deep appears on the slope without the modified CMC and the erosion area occupies 30% of the surface area. For the slope with the modified CMC，no erosion phenomenon appears after one hour of rainfall. The modified CMC has already been applied to serval construction site successfully.

Key words： slope engineering soil slope modified carboxymethyl cellulose sodium(modified CMC) erosion control
