Definitions

  • This invention relates to a method of soil stabilization and dust control utilizing aliphatic and cyclic organic compounds, specifically blends of resin acids, fatty acids and their esters with solvents that act as plasticizers and carriers.
  • Magnesium chloride, calcium chloride, and sodium chloride used in solution or solid form act as humectants when added to soil. These products work well in areas of sufficient moisture or require watering for humectants action. The problems with these products are their solubility in water and effects on ground water and plant life. In addition, as strong electrolytes they are highly corrosive to metal equipment.
  • Lignins have been employed as a low-cost means of dust control for several decades. Recently lignins have come under considerable attack by environmental, health, and safety organizations that have identified dioxin and dioxin forming compounds in lignin. This problem is compounded by lignins solubility in water and it's ability to contaminate ground water. Lignins also have a limited working life because they are water soluble they tend to be washed away with rain, melting snow, or other moisture.
  • our invention has several benefits over traditional chemical dust and erosion control, and soil stabilization agents, it can be applied neat or undiluted eliminating the chances of collateral runoff, it remains active over long periods of time requiring fewer maintenance applications, is insoluble in water resisting rain and inclement weather, contains no electrolytes thus inhibits corrosion.
  • FIG. 3 is a particle size distribution curve from a test conducted according to an alternate preferred method of this invention.
  • Aliphatic organic compounds refers to saturated and unsaturated hydrocarbons derived from petroleum, coal, or synthetic manufacturing including paraffins or alkanes, olefins, alkenes, and alkadienes. Alcohols, ethers, aldehydes, ketones, carboxylic acids, and carbohydrates. The invention is comprised 0-95% by weight of these compounds.
  • Carrier refers to any organic compounds in which carboxylic acids are miscible in and serve as a vehicle to aid in the dispersion and penetration of plasticized carboxylic acids into the soil.
  • Heterogeneous mixtures refer to mixtures or solutions comprised of two or more substances, whether or not they are uniformly dispersed.
  • Application of the chemical agent to the soil is also accomplished by the use of conventional spray equipment.
  • the agent is gravity fed or pumped through hoses, spray nozzles, or fixed sprayers and evenly applied to the soil or material to be treated.
  • Motor-graders, asphalt grinders, mixers, pug mills, compactors, rollers, and other conventional construction equipment may be utilized to blend, set grade, and compact stabilized base if desired.
  • the liquid penetrates into the soil where two mechanisms for dust control and stabilization contribute to the effect.
  • the first is a particle weighting and loading mechanism achieved through the processes of adsorption, adherence of molecules to the surface of particles and absorption, penetration of the substance into the inner structure of the particles.
  • the second mechanism is produced by the plasticized higher polymeric carboxylic acids which act as binders.
  • the fatty acids and resins bind particles into a tightly cohesive base when subjected to compactive forces.
  • the plasticized fatty acids and resins remain active even through severe wet weather and mechanical disturbances from heavy tracked vehicles and steel-chained tires.
  • Our invention displays a unique and unexpected ability to be recompacted into a tightly cohesive base when disturbed, dramatically extending the working life of the chemical agents.
  • This example discloses a formulation for producing a heterogeneous mixture depicted in our invention.

  • a 5,000 square meter test plot was prepared to test the effectiveness of the invention as a dust control agent and soil stabilizer. A severe test in an intensely utilized area was required. A slag reclamation area in the continuous caster process of a large Cleveland, Ohio steel mill was chosen for the test. The plot selected operates 24 hours/day, 5-7 days/week and averages over 100 vehicle passes per day with the majority of vehicles large pot haulers, front-end loaders with steel-chained tires, and tractor-trailers.
  • test plot was treated with the material disclosed in Example 1 over a six-week period. Three applications over the six week period were made using a conventional spray truck with a computerized spray output at an application rate of 0.39 liters/square meter each application.
  • the invention described herein consists of aliphatic and cyclic organic compounds utilized as plasticizers and carriers that are blended with materials composed primarily of thermoplastic polyolefin compounds and applied in a manner to produce improved levels of dust and erosion control, and soil stabilization.
