California is geologically active and a wide variety of soil types occur across the state. A thorough understanding of these subgrade soils in any pavement project area is essential to appropriately engineer the construction, rehabilitation, or widening of a highway facility. Subgrade is defined in the California Department of Transportation (Caltrans) Standard Specifications as “Roadbed portion on which pavement, surfacing, base, subbase, or a layer of any other material is placed.” It is the soil or rock material underlying the pavement structure, and unlike base and wearing course (surfacing) materials whose characteristics are relatively uniform, there is often substantial variability of engineering properties of subgrade soils over the length of a project.
