Description

A CHEMICAL METHOD AND COMPOSITION FOR SOIL IMPROVEMENT I. BACKGROUND

1. Technical Field

[0001] This invention relates to a method of soil improvement, erosion prevention, and dust control utilizing synthetic fluids having a substantially uniform, homogenous, engineered molecular structure, and various combinations of polyisobutylene, carboxylic acids, pour point depressants, esters, soil/ash, biodegradable fibers, wood chips, and/or synthetic fibers.

2. Background

[0002] Many methods of chemical dust and erosion control, and soil stabilization have been utilized over the years, with various detrimental effects on environment, health, and safety and varying degrees of success. Traditional products used for dust control and soil stabilization consist of used or recycled oil, virgin oils, chlorides, lignins, and emulsifications made with low- grade petroleum resins, asphalt, oil, and pitch.

[0003] Non-synthetic base oils can be volatile and change in a way that reduces the formulations stabilizing ability, may be harmful to the environment, and fail to deliver the uniform stability and strength required. These base oils have irregular, non-uniform, heterogeneous molecular structures; have double bonds, oxygen and sulfur, have weak links that volatilize under aging, compaction, and wet weather conditions, and become airborne as the base oil deteriorates. The double bonds, oxygen, and sulfur molecules are all sites for reaction and uncontrolled degradation. The products made of non-synthetic base oils can have the smaller molecules volatize and result in a changed chemical structure and changed chemical properties.

[0004] The use of used or recycled petroleum oils has long been employed as a dust control agent. In recent years legislation by most states has curtailed the use of these oils for dust control because of concerns with environment, health, and safety. This legislation has spawned an interest in virgin oils, some highly refined and very safe. The highly refined products may contain low or no aromatics but are generally cost prohibitive for most applications. In addition, petroleum oils have limited value as dust suppressants and virtually no value as soil stabilizers. They act as particle weighting agents by the processes of adsorption or absorption and do not have any significant cohesive action for soil stabilization and control of fine dust.

[0005] 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.

[0006] 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 compositions in lignin. This problem is compounded by lignins solubility in water and its 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.

[0007] Many types of emulsions of tall oil, petroleum resins, and asphalts and combinations can be prepared and have been exhibited in prior art. Typically these products are emulsified to reduce viscosity to sprayable levels and to aid in penetration of the product into the soil. One of the problems created is the use of excess liquid, which is sprayed onto the ground and can migrate into ground water. In addition, emulsions can also be severely damaged by rain and moisture when the moisture event occurs prior to the emulsion breaking and the active ingredients curing. When cured properly these products produce a bound soil layer, which is effective for dust control for short periods and under conditions where there is little mechanical disturbance. Examples of tall oil pitch emulsions that produce these results can be found in prior art. Doyle U.S. Pat. No. 5,895,347 discloses chemically stabilized emulsions of tall oil pitch, hydrochloric and stearic acids, and emulsifiers in water where temperature and pH are controlled during preparation. Additionally, Burch U.S. Pat. No. 4,822,425 discloses an emulsion comprising tall oil pitch, rosin, emulsifier, and water.

[0008] Different soil types are classified under the Unified Soil Classification System (USCS) with a two letter code. The first letter choices are G - gravel, S - sand, M - silt, C - clay, O - organic, and the second letter choices are P - poorly graded, W- well graded, H - high plasticity,

L - low plasticity. The group symbols are GW, GP, GM, GC, SW, SP, SM, SC, ML, CL, OL, MH, CH, and OH.

[0009] Binders are defined as additives to the material being agglomerated that produce bonding strength in the final product. A binder can be a liquid or solid that forms a bridge, film, or matrix filler or that causes a chemical reaction. Binders can be classified into four types. The first type is a matrix binder which is a solid or semi-solid, such as tar, pitch, asphalt, wax, or cement. Another type is a film binder, which includes water, solutions, dispersions, powders, silicate, gel, oil, alcohol, clay, and starch. The third type is a chemical binder, which reacts chemically with the material being agglomerated; these include silicate, acid molasses, lime, and lignosulphonate. The fourth type is a lubricant, which is used to reduce friction and induce flow of the material. Lubricants include oil, glycerin, stearate, and wax.

II. SUMMARY

[0010] Accordingly, several objects and advantages of the invention are superior dust control and soil improvement in areas of intense use and/or cold ground. Improved air and water quality through reduction of airborne particulates and soil erosion are achieved with use of our chemical agents formulated from safe aliphatic and cyclic organic compositions.

[0011] In addition, the invention has several benefits over traditional chemical dust and erosion control, and soil improvement 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.

[0012] A heterogeneous mixture produced by blending aliphatic or cyclic organic compositions with carboxylic acids of chemical structure R--COOH and applied to soils in a manner to produce high levels of dust control and soil stabilization. The aliphatic and cyclic compositions act as plasticizers and carriers for the carboxylic acids. When applied to soil the carrier provides a mechanism for the carboxylic acid to penetrate the soil and also acts as a dust suppressing weighting agent. The plasticized carboxylic acid provides a durable, reworkable binder that associates small particulates while stabilizing soil and aggregate. The chemical agent is manufactured and applied using conventional mixing and applied using conventional

construction equipment.

[0013] The present invention also encompasses a heterogeneous mixture produced by blending aliphatic or cyclic organic compositions with polyolefms of chemical structure C_ntl_2n or R— C_2nH_3n, and applied to soils in a manner to produce high levels of dust control and soil stabilization. The aliphatic and cyclic compositions act as plasticizers and carriers for the polyolefm to penetrate the soil and also act as a dust suppressing weighting agent. The plasticized polyolefm provides a durable, reworkable binder that associates small particulates while stabilizing soil and aggregate. The chemical agent is manufactured and applied using conventional mixing and applied using conventional construction equipment.

[0014] The present invention also incorporates a pour point depressant.

V. DETAILED DESCRIPTION

[0037] In one aspect of the present invention utilizes a composition for enhancing soil improvement characteristics in cold regions. The liquid soil improvement agent is comprised of a synthetic fluid in combination with a pour point depressant. By "synthetic" it is meant a substance, pure or a mixture, which has undergone at least one major chemical transformation (reaction) in its manufacture or processing. A simple physical separation, purification, or transformation (i.e. freezing or boiling) does not constitute a major chemical reaction. The synthetic fluid has a uniform molecular structure, and is devoid of double bonds, oxygen molecules, and sulfur molecules. The lack of these weak links means that there is a much lower probability that there will be volatilization of the reactive components and a change in the chemical structure of the synthetic fluid. With reference to FIGURES 1-3, instrumental analysis can scientifically identify both a synthetic product and a non-synthetic oil. FT-IR (Fourier transform infrared spectroscopy) and GC-MS (Gas chromatography-mass spectrometry) analysis of a product can help the user make an informed choice. FIGURE 1 is an FT-IR spectra of two synthetic fluids compared to an alkane baseline. FIGURE 2 is a prior art product Durasoil (available from Soilworks, LLC in Chandler, Arizona) compared with a fatty acid ester.

FIGURE 1 shows the match of synthetic base fluid products to the library scan of alkane, and FIGURE 2 shows a spectral match of an oil-based fluid product and fatty acid ester. With respect to FIGURE 3, GC-MS has the ability to separate and quantify unique carbon chain lengths in complex hydrocarbon mixtures. FIGURE 3 shows the population distribution of carbon chain lengths in a synthetic fluid versus and oil-based fluid. The oil-based fluid contains a wide range of carbon chain lengths averaging a much heavier weight (25.7 carbons) than the synthetic fluid (21.8 carbons). This difference of four carbons represents a chemical mass difference of 18%. On average, the synthetic alkanes are 18% lighter than comparable oil-based fiuids. As a result of their complex synthesis, synthetic fiuids contain only trace amounts of the high molecular weight carbons present in oil based fiuids. GC-MS tests were run on one aspect, and the synthetic fluid consisted of carbon chains between C9 and C41, wherein only 1.62% by weight of the fluid consisted of carbon chains above C29. Another synthetic fluid was tested, and the synthetic fluid consisted of carbon chains between C 16 and C31 , with only 0.03%> by weight of the fluid consisting of carbon chains above C29. Another synthetic fluid was tested, and the synthetic fluid consisted of carbon chains between C17 and C31, with only 2.11% by weight of the fluid consisting of carbon chains above C29.

[0038] In one aspect, a pour point depressant is added to the synthetic fluid, wherein the pour point depressant is chosen from acrylic, acrylic copolymer, polymethacrylate, ethylene vinyl acetate copolymers, vinyl acetate olefin copolymers, alkyl esters of styrene-maleic anhydride copolymers, alkyl esters of unsaturated carboxylic acids, polyalkylacrylates, alkyl phenols, alpha olefin copolymers, and polyakyl methacrylate. Incorporating the synthetic fluid and pour point depressant into soil and compacting it, will increase the soil bearing strength and other mechanical properties. The improvements in compacted soil characteristics can be achieved in cold weather environments at temperatures well below the freezing point of water. Typically, in warmer climates this soil improvement is accomplished by the use of water. This invention has the benefit over traditional methods by virtue of its ability to be dispersed and incorporated into soil at temperatures impossible for use with water due to the freezing point of water. It also remains in situ, gaining strength due to the water proofing ability, protection against freeze thaw, frost heave, and soil binding characteristics of the chemical composition. In one aspect of the invention, the synthetic fluid is about 98% to about 99.9% by weight (including, but not limited to, 98.0, 98.1, 98.2, 98.3, 98.4, 98.5, 98.6, 98.7, 98.8, 98.9, 99.0, 99.1, 99.2, 99.3, 99.4, 99.5, 99.6, 99.7, 99.8, and 99.9) and the pour point depressant is about 0.01%> to about 2% by weight (including, but not limited to, 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10, 0.11, 0.12, 0.13, 0.14, 0.15, 0.16, 0.17, 0.18, 0.19, 0.20, 0.21, 0.22, 0.23, 0.24, 0.25, 0.26, 0.27, 0.28, 0.29,

1.15, 1.16, 1.17, 1.18, 1.19, 1.20, 1.21, 1.22, 1.23, 1.24, 1.25, 1.26, 1.27, 1.28, 1.29, 1.30, 1.31, 1.32, 1.33, 1.34, 1.35, 1.36, 1.37, 1.38, 1.39, 1.40, 1.41, 1.42, 1.43, 1.44, 1.45, 1.46, 1.47, 1.48, 1.49, 1.51, 1.50, 1.52, 1.53, 1.54, 1.55, 1.56, 1.57, 1.58, 1.59, 1.60, 1.61, 1.62, 1.63, 1.64, 1.65, 1.66, 1.67, 1.68, 1.69, 1.70, 1.71, 1.72, 1.73, 1.74, 1.75, 1.76, 1.77, 1.78, 1.79, 1.80, 1.81, 1.82, 1.83, 1.84, 1.85, 1.86, 1.87, 1.88, 1.89, 1.90, 1.91, 1.92, 1.93, 1.94, 1.95, 1.96, 1.97, 1.98, 1.99, and 2.00. In another aspect, the synthetic fluid is between about 80%> to about 95%> by weight (including, but not limited to, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, and 95), the pour point depressant is between about 0.1 %> to about 0.9%> by weight (including, but not limited to, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, and 0.9), and a polyolefm is between about 5%> to about 20% by weight (including, but not limited to, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17,

18, 19, and 20). In one aspect, the application of the soil improvement composition does not require any water. The composition is a paraffin-based, hydrophobic, liquid material that can be applied at temperatures down to at least -40°F (-40°C). The composition binds and coats all contacted soil, making it water repellant while insuring compaction. The composition makes for a compacted, yet self-healing surface, in case damage at the base course occurs. It is

continuously active, therefore facilitating long-term compaction of base and sub-base soils, serving as both a densification and ballasting agent.

[0039] In another aspect of the present invention utilizes a composition for enhancing soil improvement characteristics in cold regions. The liquid soil improvement agent is comprised of a uniform molecular structure synthetic fluid, which meets EPA (Environmental Protection

Agency) standards for offshore drilling, in combination with a pour point depressant. In this aspect the synthetic fluid is defined as a fluid that meets the EPA standards for offshore drilling, including the static sheer requirement, the sediment requirement, the polyaromatic hydrocarbon requirement, and the toxicity requirement. In one aspect, the pour point depressant is chosen from acrylic, acrylic copolymer, polymethacrylate, ethylene vinyl acetate copolymers, vinyl acetate olefin copolymers, alkyl esters of styrene-maleic anhydride copolymers, alky esters of unsaturated carboxylic acids, polyalkylacrylates, alkyl phenols, alpha olefin copolymers, and polyakyl methacrylate. Incorporating the synthetic fluid and pour point depressant into soil and compacting it, will increase the soil bearing strength and other mechanical properties. The improvements in compacted soil characteristics can be achieved in cold weather environments at temperatures well below the freezing point of water. Typically, in warmer climates this soil improvement is accomplished by the use of water. This invention has the benefit over traditional methods by virtue of its ability to be dispersed and incorporated into soil at temperatures impossible for use with water due to the freezing point of water. It also remains in situ, gaining strength due to the water proofing ability, protection against freeze thaw, frost heave, and soil binding characteristics of the chemical composition. In one aspect of the invention, the uniform molecular structure synthetic fluid is about 98% to about 99.9% by weight (including, but not limited to, 98.0, 98.1, 98.2, 98.3, 98.4, 98.5, 98.6, 98.7, 98.8, 98.9, 99.0, 99.1, 99.2, 99.3, 99.4, 99.5, 99.6, 99.7, 99.8, and 99.9) and the pour point depressant is about 0.01% to about 2% by weight (including, but not limited to, 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10, 0.11, 0.12, 0.13, 0.14, 0.15, 0.16, 0.17, 0.18, 0.19, 0.20, 0.21, 0.22, 0.23, 0.24, 0.25, 0.26, 0.27,

1.13, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19, 1.20, 1.21, 1.22, 1.23, 1.24, 1.25, 1.26, 1.27, 1.28, 1.29, 1.30, 1.31, 1.32, 1.33, 1.34, 1.35, 1.36, 1.37, 1.38, 1.39, 1.40, 1.41, 1.42, 1.43, 1.44, 1.45, 1.46, 1.47, 1.48, 1.49, 1.51, 1.50, 1.52, 1.53, 1.54, 1.55, 1.56, 1.57, 1.58, 1.59, 1.60, 1.61, 1.62, 1.63, 1.64, 1.65, 1.66, 1.67, 1.68, 1.69, 1.70, 1.71, 1.72, 1.73, 1.74, 1.75, 1.76, 1.77, 1.78, 1.79, 1.80, 1.81, 1.82, 1.83, 1.84, 1.85, 1.86, 1.87, 1.88, 1.89, 1.90, 1.91, 1.92, 1.93, 1.94, 1.95, 1.96, 1.97,

1.98, 1.99, and 2.00). In another aspect, the uniform molecular structure synthetic fluid is between about 80% to about 95% by weight (including, but not limited to, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, and 95), the pour point depressant is between about 0.1% to about 0.9% by weight (including, but not limited to, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, and 0.9), and a polyolefm is between about 5% to about 20%> by weight (including, but not limited to, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20).

[0040] One aspect of the invention, utilizing synthetic fibers, gives the needed cohesion and adhesion to the treated soil, and helps prevent bulging at the heel or toe of the pad. In one aspect, the synthetic fibers are GeoFibers^® from Fiber Reinforced Soils, LLC in Baton Rouge, Louisiana. Synthetic fibers, when mixed into soil, open up to produce net, grid, and fiber configurations. These net, grid, and fiber configurations provide a mechanical means for reinforcement of the soil matrix. In this aspect, the fibers are made of polypropylene, and are between about one-quarter inch and about three inches in length (which includes, but is not limited to 0.25, 0.50, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, and 3 inches), with a tensile strength of about 40,000 psi, a tensile elongation of about 20%>, a Young's Modulus of about

600,000 psi, and a specific gravity of about 0.91 gr/cm³. In one aspect, the fibers have carbon black added as UV protection. Typically, there are three types of fibers: standard tape fibers, fibrillated fibers, and decomposing fibers. In this aspect, the fibers are added at about 0.15 pounds per square foot (0.072 millibar)-blended uniformly to about 6 inch (15.24 cm) depth and compacted.

[0041] In another aspect, uniform molecular structure synthetic fluid, a pour point depressant, and synthetic fibers are added to soil. The fluid and pour point depressant are about 5% by weight after addition to the soil, and the fibers are between about 0.3%> to about 0.5%> by weight (including, but not limited to, 0.3, 0.4, and 0.5) after addition to the soil. A treated and an untreated specimen were exposed to three subfreezing temperatures, 25°F (-3.9°C), -10°F (-

23°C), and -30°F (-34°C). Measurements were taken at ambient temperatures and after 24 hours of exposure to each temperature. The untreated specimen swelled by 7% volume at 25°F (- 3.9°C), and no more at the colder temperatures. The treated specimen shrank by 1.5% at 25°F (- 3.9°C) and did not change at the colder temperatures. It is to be understood that the synthetic fibers can be present in an amount between about 0.1% to about 5% by weight, which includes, but is not limited to 0.1 , 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1 , 1.2, 1.3, 1.4, 1.5, 1.6, 1.7,

1.8, 1.9, 2.0, 2.1 , 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1 , 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1 , 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, and 5.0. It is also to be understood that in one aspect, the synthetic fibers can be made of any plastic, elastomer, or rubber.

[0042] One method of application is that the fibers are dispersed at a certain ratio per cubic meter, blended into three lifts. The fiber length will be determined by laboratory testing. Fiber dispersing is through mechanical means and monitored for uniformity over the area. Each lift is blended uniformly with the tilling apparatus set to a specific profile. The final lift receives the fluid application along with the fiber as noted. At this point, the treated material is ready for compaction. The synthetic fluid and pour point depressant is applied to the final lift of material at a determined application rate based on the profile. About 50% of the fluid will be applied prior to the fiber application and blending. The remaining 50% is applied prior to compaction. Compaction of the treated material is done with a large compactor. The first pass is with a static roll, with the ensuing passes set for vibratory compaction. CBR values will increase over time as there is a cure time for the synthetic fluid.

[0043] In another aspect, the composition is a uniform molecular structure synthetic fluid, which in one aspect is severely hydrotreated synthetic isoalkane and binder, which in one aspect is polyolefm. The synthetic fluid can be between about 50%> to about 95% by weight (which includes, but is not limited to 50, 51 , 52, 53, 54, 55, 56, 57, 58, 59, 60, 61 , 62, 63, 64, 65, 66, 67, 68, 69, 70, 71 , 72, 73, 74, 75, 76, 77, 78, 79, 80, 81 , 82, 83, 84, 85, 86, 87, 88, 89, 90, 91 , 92, 93, 94, and 95) in this aspect and the binder can be between about 5%> and about 50%> by weight

(which includes, but is not limited to 5, 6, 7, 8, 9, 10, 1 1 , 12, 13, 14, 15, 16, 17, 18, 19, 20, 21 , 22, 23, 24, 25, 26, 27, 28, 29, 30, 31 , 32, 33, 34, 35, 36, 37, 38, 39, 40, 41 , 42, 43, 44, 45, 46, 47, 48, 49, and 50). In one aspect, the synthetic fluid/binder composition is applied as a sub-base to the soil, and on top of the sub-base, a surface course is applied, which is a combination of the synthetic fluid/binder composition and synthetic fibers. This combination of the sub-base and the surface course allows for strong impact resistance in the soil. [0044] In another aspect, uniform molecular structure synthetic fluid is combined with a pour point depressant and a thermoplastic polyolefin compound including: polyisobutylene, polyethylene, polypropylene, polybutenes, polyisoprene, and their copolymers. In another aspect, the synthetic fluid can be combined with the polyisobutylene without the pour point depressant. It is also to be understood that a binder can be added to any of the aspects as well.

In yet another aspect, synthetic fluid is combined with pitch rosin blend. Pitch rosin operates as a binder. In all of the above aspects, the synthetic fluid can be synthetic isoalkane, having an unsaturated hydrocarbon content of less that 1%, a saturate percentage of greater than 99% (although it is to be understood that the saturate percentage can also be 90, 91, 92, 93, 94, 95, 96, 97, 98, or 99%), is either a synthetic or semi-synthetic hydrocarbon, is either a hydrotreated synthetic isoalkane, a hydrocracked synthetic isoalkane, or a hydroisomerized synthetic isoalkane, has a viscosity of at least about 19 centistokes @ 68°F, a flame point greater than about 266°F, and has a flash point of about 350°F. The synthetic fluid combined with polyisobutylene helps give even distribution of the load.

[0045] In another aspect, the composition is a uniform molecular structure synthetic fluid, which in one aspect is severely hydrotreated synthetic isoalkane, and binder, which in one aspect is polyolefin. The synthetic fluid can be between about 50%> to about 95% by weight (which includes, but is not limited to 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, and 95) in this aspect and the binder can be between about 5% and about 50% by weight

(which includes, but is not limited to 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, and 50). In one aspect, the synthetic fluid/binder composition is applied as a sub-base to the soil, and on top of the sub-base, a surface course is applied, which is a combination of the synthetic fluid/binder composition and synthetic fibers. This combination of the sub-base and the surface course allows for strong impact resistance in the soil.

[0046] In another aspect, uniform molecular structure synthetic fluid is combined with a pour point depressant and a thermoplastic polyolefin compound including: polyisobutylene, polyethylene, polypropylene, polybutenes, polyisoprene, and their copolymers. In another aspect, the synthetic fluid can be combined with the polyisobutylene without the pour point depressant. It is also to be understood that a binder can be added to any of the aspects as well. In yet another aspect, synthetic fluid is combined with pitch. In all of the above aspects, the synthetic fluid can be synthetic isoalkane, having an unsaturated hydrocarbon content of less than 1%, a saturate percentage of greater than 99% (although it is to be understood that the saturate percentage can also be 90, 91, 92, 93, 94, 95, 96, 97, 98, or 99%), is either a synthetic or semi-synthetic hydrocarbon, is either a hydrotreated synthetic isoalkane, a hydrocracked synthetic isoalkane, or a hydroisomerized synthetic isoalkane, has a viscosity of at least about 19 centistokes @ 68°F (20°C) , a flame point greater than about 266°F (130°C), and has a flash point of about 350°F (177°C). The synthetic fluid combined with polyisobutylene helps give even distribution of the load.

[0047] In another aspect, uniform molecular structure synthetic fluid is combined with synthetic fibers. In this aspect, the fibers are made of polypropylene, and are between about one inch and about three inches in length, with a tensile strength of about 40,000 psi (2,758 bar), a tensile elongation of about 20%>, a Young's Modulus of about 600,000 psi (41,368 bar), and a specific gravity of about 0.91 gr/cm³. In one aspect, the fibers have carbon black added as UV protection. Typically, there are three types of fibers: standard tape fibers, fibrillated fibers, and decomposing fibers. In this aspect, the fibers are added at about 0.15 pounds per square foot (0.072 millibar)-blended uniformly to about 6 inch depth and compacted. It is to be understood that this aspect could also include a pour point depressant, a binder, and/or polyisobutylene.

[0048] There are five specific categories of base oils. These categories define the type of base stock the oil is formulated from. The categories are as follows. Note that the base oil group category is followed by the manufacturing method (in bold print) and then a description of the oil characteristics for each category.

[0049] Group I - Solvent Freezing: Group 1 base oils are the least refined of all the groups. They are usually a mix of different hydrocarbon chains with little or no uniformity. While some automotive oils on the market use Group I stocks, they are generally used in less demanding applications.

[0050] Group II - Hydro processing and Refining: Group II base oils are common in mineral based motor oils currently available on the market. They have fair to good performance in lubricating properties such as volatility, oxidative stability and flash/fire points. They have only fair performance in areas such as pour point, cold crank viscosity and extreme pressure wear. [0051] Group - III Hydro processing and Refining: Group III base oils are subjected to the highest level of mineral oil refining of the base oil groups. Although they are not chemically engineered, they offer good performance in a wide range of attributes as well as good molecular uniformity and stability. They are commonly mixed with additives and marketed as synthetic or semi-synthetic products. Group III base oils have become more common in America in the last decade.

[0052] Group IV -Chemical Reactions: Group IV base oils are chemically engineered synthetic base stocks. Polyalphaolefms (PAOs) are a common example of a synthetic base stock. Synthetics, when combined with additives, offer excellent performance over a wide range of lubricating properties. They have very stable chemical compositions and highly uniform molecular chains. Group IV base oils are becoming more common in synthetic and synthetic- blend products for automotive and industrial applications.

[0053] Group V - As Indicated: Group V base oils are used primarily in the creation of oil additives. Esters and polyolesters are both common Group V base oils used in the formulation of oil additives. Group V oils are generally not used as base oils themselves, but add beneficial properties to other base oils.

[0054] In some aspects, the invention consists of aliphatic and cyclic organic compositions utilized as plasticizers and carriers that are blended with materials composed primarily of carboxylic acids and applied in a manner to produce improved levels of dust and erosion control, and soil improvement (by soil improvement it is meant the integration of fines preservation, dust control, erosion control, soil stabilization, strength gain, and/or increased load bearing capacity).

[0055] A novel and unexpected result occurs when carboxylic acids are blended with aliphatic or cyclic organic plasticizers and carriers. These blends are processed into either heterogeneous mixtures or emulsions that applied to soil, aggregate, or mineral provide high levels of long lasting dust control and stabilization. The invention exhibits tremendous moisture resistance, reworkability, working life, while being noncorrosive and nonhazardous.

[0056] Aliphatic organic compositions 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, in some aspects, is comprised of 0% to 95% by weight (which includes, but is not limited to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, and 95) of these compositions.

[0057] Cyclic organic compositions refer to alicyclic hydrocarbons, cycloparaffins, cycloolefins, cycloacetylenes, aromatic hydrocarbons, heterocyclics, and any combinations of aliphatic and cyclic structures such as terpenes, amino acids, proteins and nucleic acids. The invention, in some aspects, is comprised of 0% to 95% by weight (which includes, but is not limited to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82,

83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, and 95) of these compositions.

[0058] Carboxylic acid refers to any substance whose major constituents are saturated or unsaturated fatty acids and their esters derived from animal or vegetable fat or oil; and vegetable derived resins or rosin acids, all represented chemically R--COOH. The invention is comprised 5% to 70% by weight (which includes, but is not limited to 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15,

16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, and 70) of these substances.

[0059] Plasticizer refers to organic compositions added to carboxylic acids to facilitate processing and increase the flexibility and durability of the final product.

[0060] Carrier refers to any organic compositions 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.

[0061] Heterogeneous mixtures refer to mixtures or solutions comprised of two or more substances, whether or not they are uniformly dispersed.

[0062] Emulsions refer to mixtures of two or more immiscible liquids held in suspension by small percentages of emulsifiers. Emulsifiers can be protein or carbohydrate polymers or long- chained alcohols and fatty acids. The emulsions can either be oil-in-water or water-in-oil continuous phase mixtures.

[0063] The invention is manufactured using conventional manufacturing equipment.

Conventional mixers, emulsifiers, or colloid mills are utilized to blend these components into stable heterogeneous mixers or emulsions.

[0064] 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.

[0065] Once applied 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.

[0066] The second mechanism is produced by the plasticized higher polymeric carboxylic acids which act as binders, in the aspects in which binders are incorporated. 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. In aspects using synthetic isoalkane, the isoalkane can provide both cohesive and adhesive effects. In aspects with esters, the ester can provide both cohesive and adhesive effects.

[0067] In some of the aspects, the composition consists of aliphatic and cyclic organic compositions utilized as plasticizers and carriers that are blended with materials composed primarily of thermoplastic polyolefm compositions and applied in a manner to produce improved levels of dust and erosion control, and soil stabilization.

[0068] A novel and unexpected result occurs when polyolefm compositions are blended with aliphatic or cyclic organic plasticizers and carriers. These blends are processed into either heterogeneous mixtures or emulsions that applied to soil, aggregate, or mineral provide high levels of long lasting dust control and stabilization. The invention exhibits tremendous moisture resistance, reworkability, working life, while being noncorrosive and nonhazardous.

[0069] Thermoplastic polyolefm composition refers to any substance derived from olefins with chemical structure C_nH_2n or R— C_2nH_3n, including polyethylene, polypropylene, polybutenes, polyisobutylenes, polyisoprene, and their copolymers. The invention, in some aspects, is comprised of 2% to 90% by weight (which includes, but is not limited to 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, and 90) of these substances.

[0070] In another aspect, a synthetic isoalkane and binder are added to in situ sand with another sand/soil mixture at 10% of the mix. The 10% sand/soil mixture in this aspect is a fine material passing a 60 sieve. In one example, the dry material was treated with water and EK35 (available from Midwest Industrial Supply of Canton, Ohio) to a moisture of approximately 7%. The EK35 was added at an application rate of one gallon per twelve square feet. The control gave a result of 10%, whereas at 0.1 penetration the result was 71.3% and at 0.2 penetration the result was 114.4%. It is to be understood that the sand/soil mixture can be between about 1% to about 15% of the mix by weight, which includes, but is not limited to, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15. It is also to be understood that the fine material of the sand/soil mixture can have a sieve range between about 4 to about 200, which includes, but is not limited to, 1, 2, 3, 4, 5, 6, 7,

8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127,

128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159, 160, 161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 181, 182, 183, 184, 185, 186, 187, 188, 189, 190, 191, 192, 193, 194, 195, 196, 197, 198, 199, and 200.

[0071] In at least one aspect, the fluid/fiber system works well with poor materials (i.e. minimal soil confinement, support, and weather). The improved soil could support and sustain high pressures for years with the worst soil and site conditions.

[0072] Accordingly, it can be seen that we have provided a unique and effective means of soil improvement using a chemical agent that provided unexpected results when tested. In one aspect, the CBR of the marginal soils was only slightly increased by the introduction of the present invention. However, the treated soil was demonstrated to have significantly increased weight-bearing properties, despite the relatively low CBR value. This result is surprising in that CBR values are associated with weight-bearing properties, so excellent weight-bearing properties for a soil with a relatively low CBR value is unexpected. A marginal soil is defined as a soil that typically will not compact sufficiently to develop the bearing strength for its indented use. This is often due to particle shapes that will not facilitate the interlocking of particles or a particle distribution that prevents coherence between particles (e.g., insufficient fines, <5%, or too much fines, > 30%). Marginal soils are often found locally to a construction site, making their potential use economically attractive. The present invention supplements the particle interlocking and cohesion of a compacted soil. Interlocking is supplemented when the ends of fibers are pinched between pairs of adjacent particles effecting mechanical reinforcement.

Cohesion is supplemented when the fluid enhances compaction and capillary action between particles. The application of the present invention to a marginal soil improves its bearing capacity via the actions just described, enabling an economical material alternative with sufficient performance for the intended use.

[0073] In a separate aspect from the previous definition of "synthetic," the definition of

"synthetic" includes the fluid meeting the EPA static sheen requirement, the sediment requirement, the polyaromatic hydrocarbon requirement, and the toxicity requirements.

[0074] In one aspect, wherein the synthetic fluid is a synthetic isoalkane, the synthetic isoalkane acts as a plasticizer, and the synthetic isoalkane is the only plasticizer. It is to be understood that this is merely one aspect of the invention, however. In another aspect of the invention, which can be combined with other aspects, the composition is essentially devoid of hydrocarbons. In one aspect, the synthetic isoalkane has a saturate percentage greater than 99%.

[0075] In another aspect, the composition consists essentially of a synthetic fluid and a pour point depressant. In another aspect the composition consists essentially of a synthetic fluid and a binder. In another aspect the composition consists essentially of a synthetic fluid, a

biodegradable material, and synthetic fibers. In another aspect the composition consists essentially of a synthetic fluid and polyisobutylene. In another aspect the composition consists essentially of a synthetic fluid and synthetic fibers.

[0076] In another aspect, the combination of synthetic fluid, synthetic fibers, and binder, all of which are described in detail above, creates a locking mechanism by which fine particles are contained. This aspect also produces increased CBR, and a waterproof surface, which is maintained in its as-constructed profile.

[0077] In one aspect of the invention, a composition for chemical soil improvement, the composition including a binder, and synthetic fibers, the composition includes a synthetic fluid combined with the binder and the synthetic fibers, wherein the synthetic fluid has a uniform molecular structure.

[0079] In one aspect of the invention, wherein the synthetic fluid has an average carbon chain length of less than 22.

[0080] In one aspect of the invention, the synthetic fluid has substantially no carbon chains above C29.

[0081] In one aspect of the invention, the synthetic fluid has 0.03% or less by weight of carbon chains above C29.

[0082] In one aspect of the invention, the synthetic fluid has between about 0.03%> by weight and about 2.11% by weight of carbon chains above C29.

[0083] In one aspect of the invention, the synthetic fluid is synthetic isoalkane, and the synthetic isoalkane is about 50%> to about 95% by weight.

[0084] In one aspect of the invention, the binder is chosen from the group comprising a carboxylic acid, an ester, and a thermoplastic polyolefm.

[0085] In one aspect of the invention, the thermoplastic polyolefm is chosen from the group comprising: polyethylene, polypropylene, polybutene, polyisobutylene, polyisoprene, and their

[0086] In one aspect of the invention, the synthetic fibers are polypropylene, are about one- quarter inch to about three inches in length, and are chosen from the group comprising standard tape fibers, fibrillated fibers, and decomposing fibers.

[0087] In one aspect of the invention, the composition further comprises a pour point depressant, wherein the pour point depressant is chosen from the group comprising acrylic, acrylic copolymers, polymethacrylate, ethylene vinyl acetate copolymers, alkyl esters of unsaturated carboxylic acids, alkyl phenols, alpha olefin copolymers, and polyalkylmethacrylate.

[0088] In one aspect of the invention, the synthetic fluid is synthetic isoalkane and the synthetic isoalkane is about 80% to about 95% by weight of a mixture of the synthetic isoalkane and the binder.
