Small amounts (usually 1 percent by weight) of hydrated lime or of Portland cement were incorporated into 1 in. thick layers of soil by laboratory mixing, followed by standard Proctor compaction and curing in a humid chamber. The resulting specimens were tested for resistance to raindrop impact erosion in a laboratory rainfall simulator, using a standard rainstorm sequence of 3-1/4 in/hr intensity applied for 1 hr on each of two successive days. For three Indiana soils tested, such treatments reduced erosion loss to almost zero; higher additions seemed to be required to stabilize a heavy montmorillonite clay soil. Application of both lime and Portland cement to the surface of specimens in slurry form was found to be reasonably effective. Cement treatments did not interfere with germination or growth of grass. A brief survey of comparative costs was made.
