In highway and railway foundation projects, the mechanical properties of foundation materials are one of the main indicators of construction process control. The elastic modulus of foundation directly affects road surface deflection and must be tested. The falling ball test method and the K30 plate load method are widely used in engineering, In order to explore the relationship between the two methods and guide the engineering application, the falling ball test method and the K30 plate load method are applied to homogeneous materials (homogeneous fine-grained material layers) and layered materials(Old foundation).Through comparative test, we found that there is a strong correlation between the falling ball test method the K30 plate load method in some scenarios,which can be used for mutual reference in engineering experiments.
