Typically, there is close relationship between the stiffness values measured with the Light Weight Deflectometer (LWD) and the field moisture content. The influence of moisture is much higher because of the capillary effect of water so the results are sensitive to...
Typically, stiffness values measured with the Light Weight Deflectometer (LWD) correlate poorly with density. Fundamentally, soil density and stiffness are two very different physical properties. Density is a static behavior depending on grain density, grain size...
This is based on the required minimum you set (Required minimum quantile:) and is a calculated value Q(Evd) = (Arithmetic average of spot-check Xm(Evd) – Required minimum quantile) / Standard deviation s (Evd) The test (Q>0,88) has failed. This comment identifies...
The wiggling shows that the material is VERY hard and the wiggling is like a vibration of the plate because of the hardness of the material (like a hammer hitting a piece of steel when you can feel the vibration).
