MODULUS OF SUBGRADE REACTION - YouTube

WebThe modulus of subgrade r e a c t i o n — often called the subgrade modulus or k—is a soil property relat- ed to how the soil reacts to load. When a slab and the loads placed on the slab put pressure on the subgrade soil, the soil deforms. It’s assumed that the deformation is proportional to the pressure.
