Bearing Capacity of 95% compacted fill Soil testing

For a well graded crushed sand and gravel (road base) I''ve seen as much as 400 kPa used (assuming that there is no underlying softer material within the zone of influence). We''ve compacted residual clayey silt to silty clay at 95% standard Proctor and obtained an effective friction angle of 32deg. Could use that to estimate bearing capacity.

Estimation of bearing capacity of floating group of stone

The stone column derives its axial capacity from the passive earth pressure developed due to the bulging effect of the column and increased resistance to lateral deformation under superimposed surcharge load, . Several experimental studies have been proposed to predict the bearing capacity of stone columns.
