Helical Probe Test (HPT)
Helical Probe Test (HPT)
(OP)
I am searching for information on the HPT test. Some 3rd party engineers in my area of the SE use this test instead of DCP or SPT to determine soil bearing. I am looking for information on validity and experimental/empirical correlations on the equipment and sources.
