A complete site characterization of the subsoil conditions down to 10 meters 32 feet was conducted at White Sands Missile Range, New Mexico. This included testing 54 borehole samples and 6 trench bulk samples for grain-size distribution Atterberg Limits, natural and hygroscopic moisture contents, moisture contents, and specific gravities. Trench bulk samples were also tested for Standard Proctor maximum dry densities and optimum water contents, unconfined compressive strengths, and triaxially-confined compressive strengths. Additional tests were performed in the field to include downhole nuclear density gauge measurements, standard penetration tests, and seismic refraction surveys. Atomic Absorbance tests and X-ray diffraction tests were conducted in the laboratory to determine concentrations and nature of calcium and magnesium in the soil. Correlations between strength values and cementation of soil particles was established as well as correlations between strength properties and seismic refraction measurements.
