Cleveland County District 1 crews partnered with Oklahoma City public works to reconstruct SW164th Street between Santa Fe and Western. Cleveland County used a new cement slurry to stabilize the road base. Previous practices have used Portland cement, lime, or class C fly ash. Chemical stabilization consists mainly of adding an alkaline binder, which is a reagent containing calcium oxide, for improving the geotechnical properties of soil. In short, it keeps water from remaining in the roadbed making it weak and spongy.
Using the dry materials would take several days of preparation and application. Thousands of gallons of water has to be used to mix in the dry materials into the soil. These dry materials are very fine.
The cement-modified soil is a soil or aggregate material that is treated with less cement than in case of hardened soil-cement. The goal is to alter properties of soils or other materials so that they are suitable for use in road construction. The cement-modified soil is usually used to improve subgrade soils or in situ aggregates to serve as a base and to substitute more costly ex-situ aggregates.
