  • Patent number: 10597838
    Abstract: A method is shown for reducing the adverse swelling action of sulfates in clay bearing soils during lime stabilization by treating soils having high sulfate content with a soluble aluminum compound that can react with the sulfate ions in the soil to form ettringite or other swelling species during the initial reaction with lime stabilization prior to compaction and paving of the lime treated soil. The amount of soluble aluminum ions added to the soil is determined by the concentration of sulfate in the soil and the other soil parameters such as the soils PI, clay type, etc.

  • Patent number: 7074266
    Abstract: A heterogeneous mixture produced by blending aliphatic or cyclic organic compounds with carboxylic acids of chemical structure R-COOH and applied to soils in a manner to produce high levels of dust and erosion control, and soil stabilization. Alternatively, a heterogeneous mixture may be produced by blending aliphatic or cyclic organic compounds with polyolefins of chemical structure CnH2n or R—C2nH3n, and applied to soils in a manner to produce high levels of dust control and soil stabilization. The aliphatic and cyclic compounds act as plasticizers and carriers for the carboxylic acids or polyolefin compounds. When applied to soil the carrier provides a mechanism for the carboxylic acid or polyolefin to penetrate the soil and also acts as a dust suppressing weighting agent. The plasticized carboxylic acid and/or polyolefin provides a durable, reworkable binder that associates small particulates while stabilizing soil and aggregate.

The endosperm comprises the carbohydrate and protein portions of grains, seeds, or tubers. The strong base is reacted with the endosperm in the presence of water added in order to ionize the carbohydrate and protein of the endosperm and render them more soluble or dispersible in water. The iron compound promotes an electrochemical reaction that assists in the formation of a silicate crystal matrix when applied to soil. The fibrous material softens and nourishes the soil in order to promote the emergence of plant life and/or seed germination. Seeds may optionally be added to further promote vegetation or revegetation of denuded soils.

  • Publication number: 20040208709
    Abstract: Embodiments of the present invention are methods and chemical compositions of polymers and crosslinking agents that are particularly suited to aggregate, including soil and other natural aggregates, stabilization via hydraulic application. The present invention is an improvement over existing methods as it provides effective stabilization for longer periods. The compositions, when in an aqueous solution and applied to soil or aggregate surfaces, penetrate the surface polymerize and form a crosslinked polymer film. Individual aggregate particles may bind to the polymer or may be entrapped by the polymer film. In the environment, the film is substantially resistant, in the near term, to biodegradation and natural, physical degradation due to weathering and exposure. The resultant polymer film and aggregate or bonded fiber matrix resists erosion by strong wind and heavy rain but readily allows seeds to germinate and grow.

  • Publication number: 20020026881
    Abstract: Physiologically acceptable and non-corrosive silicone compositions are used for treating surfaces such as glass, porcelain, ceramic, marble, granite, metal, coated metal, plastic, wood, painted wood, cement, leather, textile, cloth, and other hard or soft composite surfaces, to render them water and soil repellent. Volatile organic compound (VOC) free cream, paste, powder and solid compositions are provided by the inclusion of particulate stabilizers in the silicone compositions. Solventless silicone compositions provide numerous advantages with improved water and soil repellency qualities.

  • Patent number: 6280521
    Abstract: A method is disclosed for constructing, verifying, and maintaining underground vaults that isolate and contain radioactive burial sites. The method employs a buoyant lift technique to isolate a block of soil containing the contaminates from the surrounding soil. An impermeable synthetic liner is embedded in the vault to enhance the integrity of the system. The integrity of the vault is monitored by a system of sensors placed both inside and outside of the sealed vault. The method eliminates the need to excavate or drill in the contaminated areas.

  • Patent number: 6258160
    Abstract: The present invention provides improved methods and compositions for grouting heat exchange pipe in a hole or trench in the ground. The grouting compositions of the invention have quick set and high thermal conductivity properties and are basically comprised of an amorphous silica material, an alkaline earth metal oxide or hydroxide, a water swellable clay and water present in an amount sufficient to form a slurry. The compositions optionally also include a set retarder and a thermal conductivity increasing agent.

  • Patent number: 6065903
    Abstract: Methods are disclosed for preparation of chemically-stabilized emulsions of tall oil in water. Temperature and pH are controlled during preparation of the emulsions so as to prevent saponification and neutralization of acids in the tall oil component. The final emulsions have pHs in the range of from about 3.0 to 5.0 and remain phase stable for extended periods of time. Methods are disclosed for using the emulsions for soil treatment to improve soil stabilization and load bearing capacity for roadbed use, for treatment of reclaimed asphalt pavement for reuse as a stabilized base course for roadway construction and for remediation of heavy metal contaminated soil.
