This UFC documents the standard practice for improving the engineering properties of soils used for operating surfaces, pavement base courses, subbase courses, and subgrades by the use of additives mixed into the soil to effect the desired improvement. It also provides criteria and guidance for the stabilization and modification of soils for pavements, operating surfaces, and construction platforms. This UFC is also applicable to roads, airfields, and construction
platforms having a stabilized surface layer. These soil improvements consist of applying a chemical such as lime, cement, or bitumen to a layer of soil or aggregate that will be included within a pavement area. Stabilization or modification measures discussed herein are useful to limit expansive soil's ability to expand and contract due to changes in moisture content, increase the soil's shear strength to prevent or minimize pumping, or to bind soils or aggregates.
