REPORT TERMINOLOGY <br />(Based on ASTM D653) <br />Expansive The potential of a soil to expand (increase in volume) due to absorption of moisture. <br />Potential <br />Finished Grade The final grade created as a part of the project. <br />Footing A portion of the foundation of a structure that transmits loads directly to the soil. <br />Foundation The lower part of a structure that transmits the loads to the soil or bedrock. <br />Frost Depth The depth at which the ground becomes Frozen during the winter season. <br />Grade Beam A foundation element or wall, typically constructed of reinforced concrete, used to span <br /> between other foundation elements such as drilled piers. <br />Groundwater Subsurtace water found in the zone of saturation of soils or within fractures fn bedrock. <br />Heave Upward movement. <br />Lithologic The characteristics which describe the composition and texture of soil and rock by <br />observation. <br />Native Grade The naturally occurring ground surface. <br />Native Soil Naturally occurring on-site soil, sometimes referred to as natural soil. <br />Optimum Moisture The water content at which a soil can be compacted to a maximum dry unit weight by a <br />Content given compactive effort. <br />Perched Water Groundwater, usually of limited area maintained above a normal water elevation by the <br />presence of an intervening relatively impervious continuous stratum. <br />Scarify To mechanically loosen soil or break down existing soil structure. <br />Settlement Downward movement. <br />Skin Friction (Side The frictional resistance developed between soil and an element of the structure such as a <br />Shear) drilled pier. <br />Soil (Earth) Sediments or other unconsolidated accumulations of solid particles produced by the physical <br />and chemical disintegration of rocks, and which may or may not contain organic matter. <br /> <br />Strain The change in length per unit of length in a given direction. <br />Stress The force per unit_area acting within a soil mass. <br />Strip To remove from present location. <br />Subbase A layer of specified material in a pavement system between the subgrade and base course. <br />subgrade The soil prepared and compacted to support a structure, slab or pavement system. <br /> <br />
