Portable penetrometer correlation with STP
Portable penetrometer correlation with STP
(OP)
I'm seeking a correlation between portable penetrometer (specifically, a Porta-Pen) and standard penetration testing. The CPT-SPT correlation is not applicable. I've requested the 1966 G.F. Sowers paper from ASTM Special Technical Publication 399. Does anyone know of any other resources? Thank you.

The DCP does not work well below the water table unless the borehole is stabilized to prevent inflow and soil softening. The DCP is of limited use in evaluating alluvial soils of Piedmont or Blue Ridge origin (which includes the Upstate of South Carolina and western North Carolina) in that the calibration ratios vary without specific pattern.
