DCP Australia (9kg, 30 degrees) for bearing capacity

[Alvinz]

A task was given to use DCP Australia (9kg, 30 degrees, blows for every 100mm ) to test for bearing capacity. The test is carried out for crane pad purposes.

The question is how to workout the bearing capacity based on the dcp results? Thank you

Sounds a bit like the Mackintosh Probe - but the Machintosh uses a 5 kg hammer. In any event, I've attached a couple of web sites for you to look at and see how they develop "supposedly" safe bearing pressures.
