Plate Bearing Tester also known by a number of different names that include:

Static load plate bearing tester Static plate bearing test Plate bearing tester Static plate test Static plate bearing test Plate load test Static plate load test AX01

---

Ev1 – deformation modulus (static plate loading test) or strain modulus first loading cycle for the bearing capacity

---

Ev2 – deformation modulus (static plate loading test) or strain modulus second loading cycle for the bearing capacity

---

The ratio Ev2/Ev1 is a figure for the compaction level

---

Ev2 and Evd relationship – the relationship between the static deflection modulus Ev2, measured by the static plate bearing test, and the dynamic deflection modulus Evd depends on the kind of soil and the degree of compaction.

Experience shows that the ratio Ev2/Evd lies in the range 1.0 to 4.

For densely compacted soils Ev2/Evd ~ 2.3

On average the following relation between the dynamic deflection modulus Evd, and the static deflection modulus Ev2, can be used:

This relation does not hold for limiting values.
