“…can also be calculated [5] . According to the Hertz impact theory, when a sphere with known rigidity collides with an object with unknown rigidity, the greater the rigidity of the object will lead to the shorter the contact time (T c ) during the collision [6] . However, Hertz impact contact theory is only applicable to linear elastic materials, while geomaterials are typical elastoplastic materials.…”

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.

The detection of the deformation characteristics of geotechnical materials is very important for improving the safety of highways. With the improvement of the detection technology, the falling ball test (FBT) method has been gradually applied to measure mechanical properties of the geomaterials. In order to determine the reliability and the stability of the FBT method, the results of using the FBT method to detect the deflection value of the cement stabilizing layer are compared in this paper with the results of using a falling weight deflectometer (FWD), which is recognized worldwide as an ideal non-destructive detection equipment for the road mechanical performance. It is found that FBT method has high stability and reliability during the test.

In filling engineering, the mechanical properties of geomaterials are the most important mechanical indicators. With the improvement of the measurement technology, the falling ball test (FBT) method has been gradually popularized and applied to the testing of geomaterials mechanical properties. In order to verify the testing accuracy of the FBT method, experimental results of the deformation modulus tested for the homogeneous fine-grained materials and the layered structures using the FBT method are compared with the K 30 plate load test, which is the earliest and the most widely used in-situ test method. And some conclusions are drawn in this present paper.
