Plate Bearing Test

This is for estimating the bearing capacity of shallow foundations in situ and for the design of flexible pavement. In the test procedure a steel plate is subjected to gradually increasing load and settlements of the plates recorded. Maximum bearing capacity is noted as that load at which the plate starts sinking rapidly.
