摘要： Disclosed is a soil stabilizing agent consisting of a source of calcium, such as calcium carbonate, and a spent sulfuric acid, in a water solution and a method for applying the same. Certain chloride and sulfate materials, such as aluminum and ferric chloride and aluminum and ferrous sulfate, may be added to the soil with the stabilizing agent to provide enhanced results in particular soils. The stabilizing agent is applied with sufficient water to thoroughly wet the soil and thus disperse the agent through the soil and the treated soil is then worked to accomplish thorough mixing. An alternate method of application is also disclosed in which the calcium source material, and the chloride or sulfate materials if used, are applied dry in powdered or granular form to the soil surface, the soil and materials are treated with a solution of water and a spent sulfuric acid sufficient to thoroughly wet the soil to the desired depth of treatment and disperse the chemicals therein, and the chemicals and soil are then worked until thorough mixing is assured.
