The moisture content has a <br />significant effect on the strength, compressibility and general behavior of the soil. <br />Calibrated Pocket (Hand) Penetrometer Testing <br />This test involves pushing a spring-loaded piston, 0.25-in. in diameter, into the sample and <br />measuring the spring deflection, which has been correlated to shear strength. This test is used <br />as a rough approximation method only. More refined results require undisturbed Shelby tube <br />sampling and laboratory unconfined compressive strength testing.
