Non-Nuclear Density Gauges

Model No. NND-0004 · Geotechnical Field Testing Equipment

Soil Stiffness Gauge

土壤刚度仪

Pavement design uses modulus, so measuring stiffness directly in the field avoids converting from density. This gauge vibrates a 114 mm ring foot at 25 frequencies between 100 and 196 Hz, measuring stiffness of 3–70 MN/m and Young's modulus of 26–610 MPa. Each test takes about 75 s and reaches roughly 230–300 mm deep.
