Penetration resistance was measured in situ by the procedures of the ASTM standard penetration test. Selected horizons were tested at five sites of each of two soil series. Presumptive bearing value is shown to be influenced most strongly by soil moisture content, bulk density, and clay content. These variables explain 78% of the variation in presumptive bearing value. Soil strength as determined by this test and the vane shear tests were compared and found to be very similar; however, the penetration test is less sensitive to differences in soil moisture content. Determination of presumptive bearing value using the penetration test provides information useful to understanding the behavior of specific horizons of soil series.
