The quantit of erosed fine grained soils stabilized w ith inorganic binder increases with time linearl , while quantit of erosed coarse grained soils stabilized w ith inorganic binder increases rapidl in the earl stage and slowl later; as for soils stabilized with the same t pe of inorganic binder, its erosion is weaker when more binder is added; the degree of com- paction of samples affect its erosion greatl ; the relationship between ant-i erosion properties of base course materials and its compressive strength is not simple; short experimental time can t fairl reflect anti-erosion properties. The anti-erosion mechanism is also anal zed in this paper.
