AASHTO T207
Full Name
AASHTO T207 – Standard Method of Test for Thin-Walled Tube Sampling of Soils
Scope
This method covers a procedure for using a thin-walled metal tube to recover relatively undisturbed soil samples suitable for laboratory tests of engineering properties, such as strength, compressibility, permeability, and density.
Thin-walled tubes used in piston-, plug-, or rotary-type samplers, such as the Denison or Pitcher, must comply with the portions of this practice that describe the thin-walled tubes.
