Supervisor: Mike Sprague - (208) 334-8297           The Soils Laboratory performs tests to determine physical and mechanical properties of soils, such as gradation, Atterberg limits, specific gravity and permeability for classification and R-value and resilient modulus for pavement design. The Geotechnical Laboratory performs tests on both undisturbed or remolded samples to determine physical and mechanical properties of soils, such as shear strength and compressibility, for design of slopes and structure foundations. The Geotechnical Laboratory also performs tests to determine physical and mechanical properties of rock cores and geosynthetics such as geotextiles and geogrids.
