The prevention of reddish soil loss in Kunigami Maaji areas is very important in environmental conservation for the coral reef region in Okinawa, Japan. In this paper, the mechanical properties and erosion loss characteristics of cement-stabilized soil were investigated in order to provide material for soil structures such as embankment. Erosion tests for stabilized soils were carried out in field to examine the effects of cement content on soil loss. The stabilized soils having cement contents more than 2.5% were significant for preventing soil loss. For clarifying out the mechanical properties of cement-stabilized soil, soil compaction tests, slaking tests, unconfined compression tests and CBR tests were carried out. Furthermore, from the results obtained the effects of cement content and drying-wetting on those properties were discussed. Cement treatment is a useful method to improve those mechanical properties and control the soil loss in surface layer of soil structures
