Plate Bearing Test
Summary
Plate Bearing Test - The plate bearing test is an in-situ soil test used to find the Modulus of Subgrade reaction k used in slab designs. The test should be carried out in accordance with EN 1997-2.
Technical Information
The plate bearing test involves the loading of a steel plate of known diameter whilst it is resting on the subgrade. The applied load is increased over time and the resultant deflection recorded.
The larger the plate the greater the accuracy of the results, it is preferred that the maximum plate diameter of 762mm is used.
The frequency of the plate tests should be no less than one per 2000m2 of floor.
