Feb 01, 2012 · subgrade or subbase for highway and runway design and construction. Field plate load test is commonly used to pre-dict the deformations and failure characteristics of the soil/subgrade and modulus of subgrade reaction (k. s). Modulus of subgrade reaction (k. s) is used in foundation design, soil-structure interaction studies and design of
