Abstract :Activity index insert ignore into journalissuearticles values(AI); value characterizes the relationship between the plasticity index and clay content. In this study, AI value was investigated to determine whether it might be used as an indicator of soil structural stability or not. The AI values of 75 soil samples gave the significant negative correlations with their dispersion ratio insert ignore into journalissuearticles values(DR);, soil erodibility factors insert ignore into journalissuearticles values(K); and erosion ratios insert ignore into journalissuearticles values(ER);. Also, the AI values of the soils including clay and sandy clay loam textural class showed significant positive correlation with soil structural stability index insert ignore into journalissuearticles values(SSI);. It seems that the AI value may be used as an indicator of soil structural stability.
Keywords : AI value, erosion ratio, soil erodibility, structure stability index
