EVD Hand-Held Falling Weight Deflectometer is used to measure the deflection value of the subgrade under dynamic loads,thereby evaluating the bearing capacity and deformation of the subgrade.
EVD Hand-Held Falling Weight Deflectometer is used to measure the deflection value of the subgrade under dynamic loads, thereby evaluating the bearing capacity and deformation of the subgrade. It simulates the impact effect of a high-speed train on the subgrade. Compared with static load tests, it can better reflect the actual stress conditions of the subgrade soil. It can quickly measure the dynamic deformation modulus Evd value.
