Cement stabilizes soil in two ways. First, it reduces soil plasticity, especially for the soil in which there is high amount of clay particles.
A cement-modified soil cement pavement contains relatively small proportion of Portland cement. The result is caked or slightly hardened material, similar to a soil, but with improved mechanical properties - lower plasticity, increased bearing ratio and shearing strength, and decreased volume change.
A soil-cement base contains higher proportion of cement than cement-modified soil.
It is commonly used as a cheap soil cement pavement base for roads, streets, parking lots, airports, and material handling areas. A cement-treated base is a mix of granular soil aggregates or aggregate material with Portland cement and water.
soil cement pavement Acrylic copolymer Rhino Snot: Developed for the U. Military in desert conditions and commercially trademarked, "Rhino Snot" is a water soluble acrylic copolymer applied to soil or sand which penetrates and coats the surface.
Large paved areas must maintain their original grade and must not develop depressions or potholes if they are to drain freely during rains, 13 Stabilized Base vs.
Samples taken after 15 to 20 years show considerably greater strength than sample taken when the pavement was initially built. soil cement pavement
Review and Evaluation of Soil-Cement Pavements
It is similar in use and performance to soil-cement base. Acrylic copolymer Rhino Snot [ edit ] Developed for the U.
Military in desert conditions and commercially trademarked, "Rhino Snot" is a water-soluble acrylic copolymer applied to soil or sand which penetrates and coats the surface.
When dry, it forms a soil cement pavement, UV-resistant, solid bond which soil cement pavement the soil together, reducing dust.
In higher concentration it creates a durable surface that can withstand heavy traffic, allowing existing soil to be used for roads, parking lots, trails and other heavy traffic areas. If damage occurs from spikes or other point forces, it is repaired easily by filling the holes with a pourable mixture of PolyPavement and the natural soil or patching by spreading and compacting a drier PolyPavement and soil mix into the damaged area.
PolyPavement never needs to be removed and replaced as with asphalt and concrete.

Instead, after it wears, more PolyPavement can be applied on top of old PolyPavement inexpensively to extend the life of a Natural Soil Pavement soil cement pavement indefinitely. Environmentally Safe PolyPavement is non-toxic to plants and animals. It has been tested and proven safe for sensitive aquatic life.
