[0007] 2. Brief Description of the Related Art

[0008] Asphalt is a sticky, black and highly viscous liquid or semi-solid that is present in most crude petroleum and in some natural deposits. In U.S. terminology, asphalt (or asphalt cement) is the carefully refined residue from the distillation process of selected crude oils. Outside North America, the product is called bitumen. [0009] Asphalt binder is a key ingredient in pavements, roofing and waterproofing applications. The primary use of asphalt is in road construction, where it is used as the glue or binder for the aggregate particles, and accounts for approximately 80% of the asphalt consumed in the United States. The most common type of flexible pavement surfacing in the United States is hot mix asphalt (HMA) that may also be known by many different names such as hot mix, asphalt concrete (AC or ACP), asphalt, blacktop or bitumen.

[00010] After use of asphalt in road construction, roofing applications, mainly in the form of roofing shingles account for most of the remaining asphalt consumption. Other uses include waterproofing applications.

[00011 ] Concerns over peak oil, pollution, climate change, urban heat islands, oil price fluctuations, and/or changes in refinery operations, have provided incentive to consider non- petroleum alternatives.

[00012] As an example, asphalt prices are escalating sharply due to supply/demand of crude oil and also because more refineries are installing cokers to convert asphalt and asphalt like residues into transportation fuels to meet growing demand. This means that asphalt binder will continue to become limited in supply and will become progressively more expensive.

[00013] As another example, emissions from asphalt binders derived from petroleum sources are of concern due to their composition of sulfur compounds, poly-nuclear aromatics and Nitrogen compounds. This poses a health hazard for employees in the aggregate mixing and paving operations as well as to the motoring public during paving operations.

[00014] Bioasphalt is an asphalt alternative made from non-petroleum based renewable sources.

[00015] These renewable sources include sugar, molasses and rice, corn and potato starches, natural tree and gum resins, natural latex rubber and vegetable oils, lignin, cellulose, palm oil waste, coconut waste, peanut oil waste, canola oil waste, potato starch, dried sewerage effluent and so on. Bitumen can also be made from waste vacuum tower bottoms produced in the process of cleaning used motor oils, which are normally burned or dumped into land fills. Non-petroleum based bitumen binders can be colored, which can reduce the temperatures of road surfaces and reduce the urban heat islands. [00016] The use of tall oil in asphalt compositions and products has been known for a long time as shown in the following patents.

[00046] DETAILED DESCRIPTION OF THE INVENTION

[00047] The present invention utilizes tall oil materials in asphalt compositions and products. Some embodiments of the present invention utilize tall oil materials having an increased softening point. In some embodiments, part or all of the tall oil materials are oxidized to increase the softening point, while keeping viscosity as low as possible. In other embodiments, part or all of the tall oil materials are distilled to increase the softening point, generally by removing the lighter fractions. In even other embodiments, part or all of the tall oil materials may be both oxidized and distilled, in either order. In still other embodiments, various parts of the tall oil materials may be oxidized and/or distilled. As non-limiting examples, one part oxidized and one part distilled, or one part oxidized and one part both oxidized and distilled, or one part distilled and one part both oxidized and distilled, or even one part oxidized one part distilled and one part both oxidized and distilled. In still other embodiments, the tall oil materials (oxidized, distilled, or not) are combined with a polymer to increase the softening point. In the practice of the present invention, tall oil materials, especially oxidized tall oil, may be used as an additive to partially or fully replace petroleum based asphalt binders.

[00048] It is believed that any known asphalt composition or product may be made using the tall oil materials of the present invention to replace part or all of the petroleum based asphalt binder therein. The known equipment and methods of making the known asphalt compositions and products are believed to be sufficient for making the asphalt compositions and products of the present invention in which part or all of the petroleum based asphalt has been partially or wholly replaced by the tall oil materials of the present invention. [00049] As used herein, including the claims, "tall oil materials" includes man made and naturally occurring tall oil, tall oil pitch, tall oil blends, and similar tall oil products. Tall oil is a liquid resinous material that may be obtained in the digestion of wood pulp from paper manufacture. Commercial tall oils comprise a complex of fatty acids, resin acids, sterols, higher alcohols, waxes and hydrocarbons. The acid components also may be present as the esters thereof.

[00050] A common source of tall oil that may be used in the practice of the present invention is from pine trees. Besides cellulose, tall oil contains fatty acids, esters, rosin acids, sterols, terpenes, carbohydrates and lignin. These may be separated when wood is converted to paper pulp by the sulfide or Kraft process. The acids may then be neutralized in an alkaline digestion liquor. The mixture of rosin and fatty acid soap may be recovered by subsequent acidification which releases free rosin and fatty acids, the major constituents of tall oil.

[00051 ] In certain embodiments of the present invention, it is desired to utilize a tall oil material in which part, parts or all of the tall oil material has been subject to oxidation and/or distillation, which tall oil material may be utilized either on a neat basis or in combination with various polymers. The purpose of the oxidation and/or distillation of the tall oil material and the combination with a polymer is to increase the softening point, while keeping viscosity as low as possible.

[00052] The tall oil materials suitable for use in the present invention product can be produced using various tall oil streams - crude tall oil (CTO) or tall oil pitch (TOP). These two tall oil sources may first be modified, either by distillation and/or oxidation, and used either on a neat basis or in combination with various polymers. One purpose of the modification of the tall oil material and the optional combination with a polymer is to increase softening point, while keeping viscosity as low as possible, for use in asphalt applications.

[00053] In the case of tall oil that is used on a neat basis i.e., no polymer added, the tall oil is oxidized to a high level in order to achieve a softening point in the range of about 75°F to about 400°F. The upper limit of the softening point is generally determined by viscosity issues, in that the tall oil must have suitable workability/flowability. The lower limit of the softening point is generally determined by flash point issues. Certainly, viscosity modifying agents may be utilized, but there is also a limit to how much these agents can help the workability/flowability. Generally the lower end on the range of softening points may be selected from 75°F, 85°F, 95°F, 100°F, 110°F, 125°F, 150°F, 175°F, 200°F, 225°F, 250°F and 300°F, with a corresponding higher upper end for the range of softening points selected from 85°F, 95°F, 100°F, 110°F, 125°F, 150°F, 175°F, 200°F, 225°F, 250°F, 275°F, 300°F, 350°F, 375°F and 400°F. Non-limiting examples of other suitable ranges include in the range of about 100°F to about 275°F, and even in the range of about 125°F to about 250°F.

[00054] The extent of oxidation may be determined through acid value determination (as measured in mg/g), that is, when the tall oil materials are oxidized, the acid value will decrease. The ending acid number will depend on the starting acid number, as not all crude tall oils or tall oil pitches will have the same starting acid number, so it will be necessary to observe the decrease in acid number. As a non-limiting example, for some lightly oxidized tall oil pitches, the acid number reduction will be in the range of about 5 to 20 titration units. As a non-limiting example, for some lightly oxidized crude tall oils the acid number reduction is in the range of about 5 to about 25 units. Certainly, there will be tall oil materials for which the acid number reduction may be greater or less than that described above, with the end softening point and the end viscosity being the determining factors for the extent of oxidation. The upper limit may be influenced by one or more of the end viscosity, end softening point, end needle penetration, and/or the end water solubility, depending upon which of those properties are desirable. Specifically, with increasing oxidation the viscosity increases, the softening point increases, the water solubility decreases, and the needle penetration decreases. In many embodiments, it is the viscosity that will be the more important factor in the end application, as with too much oxidation, the tall oil material will become too viscous for pumping or use in asphalt. Certainly, there may be some embodiments in which either the softening point or water solubility controls the amount of oxidation. The present invention anticipates the use of oxidized and/or distilled (in any order) crude tall oil, oxidized and/or distilled (in any order) pitch, and/or highly oxidized and/or distilled (in any order) crude tall oil, preferably, oxidized and/or distilled (in any order) pitch, and/or highly oxidized and/or distilled (in any order) crude tall oil.

[00055] As non-limiting examples, the tall oil used can be crude tall oil, distilled crude tall oil (with 1% to 30% of light ends removed via distillation) or tall oil pitch. As other non- limiting examples, this distillation process can be carried out in a wide range of equipment - a conventional rectification column, a thin film or wiped film evaporator, a falling film evaporator or even done as a batch flash. As a non-limiting example, a single stage wiped film evaporator may be utilized with run conditions in the evaporator at 165°C at a vacuum of 200 microns. Certainly numerous other process conditions may be selected, for example, less vacuum could be used if higher run temperatures are used. The exact equipment used and feed stock will determine the actual run conditions. In some embodiments of the present invention, light ends distilled from tall oil materials via distillation are used as an asphalt diluent.

[00056] As a non-limiting embodiment of a suitable oxidation process, the tall oil material is charged to a batch reactor and is oxidized by blowing air into the reactor mass under controlled conditions of temperature and pressure. One non-limiting way to control the degree of oxidation, and thus the softening point and viscosity, is by oxidation time. The longer the oxidation time, the higher the softening point and the greater the viscosity.

[00057] Generally speaking, the rate of oxidation is increased through higher pressure, higher temperature, higher air rates and improved air dispersion through agitation, pressure and sparging. As non-limiting examples, run conditions used on a pilot plant scale to produce highly oxidized tall oil were 240°C, atmospheric pressure and an air rate of approximately 16 to 25 standard cubic feet per hour of air per kilogram of reactor charge. Oxidation time was approximately four (4) hours. The air rate used on a pilot scale was perhaps a bit high to be achieved commercially. Certainly lower air rates and lower temperatures can be used, and will result in increased reaction time, however. It is also important to note that the oxidation process is an exothermic reaction, so cooling must be provided to control reaction temperature once the process is begun. Additionally, some embodiments include a reactor equipped with a vent condenser in order to capture any tall oil that is vaporized from the reactor or entrained with the exhausting air.

[00058] Non-limiting examples of operating ranges to produce highly oxidized tall oil materials, are as follows: temperature in the range of about 200°C to about 260°C, and operating pressure on the order of about 40 psig. Certainly, the operating pressure may be in the range of about 0 psig (atmospheric conditions) to about 150 psig psig, but oxidation at higher pressures reduces the loss of lighter end material through the reactor vent. Depending upon the equipment utilized and other process conditions, a non-limiting air rate will be on the order of about 1 to 30 scfh/kg (standard cubic feet per hour per kilogram of material). [00059] In other certain embodiments the tall oil materials (oxidized, distilled, both or neither) can be combined with various polymers to elevate the softening point. As non- limiting embodiments, the polymers may be blended with the various tall oils at a suitable temperature, so that all components are in a dispersed in order to facilitate blending (non- limiting examples in the range of about 175°C to 250°C - preferably 165°C to 200°C). Non- limiting examples of polymers suitable for use in the present invention include Latex

Emulsion, Styrene Butadiene Styrene, natural or synthetic Styrene Butadiene Rubber, Styrene Ethylene Butadiene Styrene, Polypropylene (polymer or wax), Polyethylene (polymer or wax), Atactic-Polypropylene, Fischer- Tropsch Wax, Microcrystalline Wax, Crumbed Tire Rubber, Ethylene Vinyl Acetate, Terpolymers, Montan, Epoxy Resins, Petroleum Wax, PTFE, or any conventionally used asphalt modifier to form the binder component as may be desired for the particular end use application. As a non-limiting example, the range of polymer used in combination with the tall oil is 0.5% to 25%, preferably 5% to 10% weight percent, based on the weight of the tall oil. The level of polymer used sets the softening point of the blend. It is important that a homogeneous, stable blend is produced and this may be achieved with or without cross-linking agents. As a non-limiting example, blending time is typically 10 minutes to 24 hours under good agitation at the temperature range described above.

[00060] In certain embodiments of the present invention, it is desired to utilize a tall oil material that has a suitable water solubility for the end use application. As a non-limiting examples, one method for obtaining suitable water solubility is by selecting the desired amount of oxidation. Certainly, additives may be utilized to achieve the desired property. Generally, for those end use applications in which exposure to the elements, water and/or humidity is an issue, the water solubility is generally less than 10%. There may be end use applications in which a lower solubility may be desired, non-limiting examples of which include less than 7%, less than 5%, less than 3%, less than 2%, less than 1%, less than 0.5%, and perhaps even less than 0.25%.

[00061 ] In certain embodiments of the present invention, it is desired to utilize a tall oil material that has needle penetration suitable for the end use application. As a non-limiting examples, one method for obtaining suitable needle penetration is by selecting the desired amount of oxidation. Certainly, additives may be utilized to achieve the desired property. Generally, depending upon whether it is desired to have a hard rigid asphalt or a soft pliable asphalt, the needle penetration may as a non-limiting example, range from about 1 to about 400 (as measured at 25°C), with the hard rigid asphalts on the lower side, and the soft pliable asphalts on the higher side of that range. As further non-limiting examples, for a hard rigid asphalt the needle penetration may be in the range of about 1-100, 1-50, and 1-25, and for soft pliable asphalt in the range of about 200-400, 250-375, and 250-350.

[00062] In certain embodiments of the present invention, it is desired to utilize a tall oil material that has a rotational viscosity suitable for the end use application. As a non-limiting example, one method for obtaining suitable rotational viscosity is by selecting the desired amount of oxidation. Certainly, additives may be utilized to achieve the desired property, but there is also a limit to how much these agents can help the workability/flowability. The suitable rotational viscosity is generally dependent upon the workability/flowability needed in the end use application. As one-non-limiting example, the upper limit of the rotational viscosity may be determined by cold weather cracking and/or slow down in processing speed at the end use application. As a non-limiting example, the lower limit of the rotational viscosity may be determined by the flash point. Generally the lower end on the range of rotational viscosity at 275F may be selected from 650 cps, 700 cps, 800 cps, 900 cps, 1,000 cps and 1,100 cps, with a corresponding higher end for the range of rotational viscosity selected from 3,000 cps, 4,000 cps, 5,000 cps, 6,000 cps, 7,000 cps, 8,000 cps. Non-limiting examples of a suitable range includes in the range of about 650cps to 8,000 cps at

135C/275F.

[00063] A non-limiting examples of a suitable oxidized tall oil asphalt binder may appear black in color, and may have a Softening Point as discussed about and optionally a Needle Penetration value (0.1mm) at 25C of 1 or higher and Rotational Viscosity at 150°F in the range of 2,000cps to 15,000 cps, or a Rotational Viscosity at 135C/275F with lower limit at 650cps and higher limit at 8,000 cps..

[00072] EXAMPLES

[00073] The following non-limiting examples are provided merely to illustrate the present invention and are not meant to limit the scope of the claims in any manner.

[00074] Example 1 Effect of Contribution of Oxidized Asphalt to Binder Stiffening

[00075] A lightly oxidized tall oil component is prepared by first charging

approximately 3.2 kilograms of crude tall oil into a laboratory flask. The laboratory flask is equipped with a dip tube for the addition of air, an agitator and an electrically controlled heating mantle. The crude tall oil is heated to approximately 240°C while being agitated. Once the reactor mass reaches 240°C, air is introduced, as measured using a rotameter, at a rate of approximately 75 scfh (standard cubic feet per hour, or 23.4 scfh/kg, under

atmospheric pressure. The heating mantle is turned to off as the oxidation reaction generates adequate heat to maintain the reaction temperature. After approximately one hour, air addition is ceased and the material is allowed to cool to approximately 200°C. At this temperature, and with the agitator still in operation, 0.356 kilograms of a polyethylene wax (polymer) is added to the oxidized tall oil and allowed to mix for one hour. The resulting oxidized tall oil/polymer blend has a softening point of approximately 60C and a rotational viscosity of approximately 4,000 cps at 135C/275F.

[00076] 600g base asphalt, Valero PG 67-22 was weighed out into a quart can. 200g of the oxidized tall oil was pre-melted and added to the quart can containing the 600g Valero base. The contents were placed into a heating mantle and the temperature was raised to 300F while mixing under low shear (1500rpm) using a Silverson Mixer. After 20 minutes of mixing, the sample was removed and cooled to room temperature and then the can was sealed and sent to Dongre Laboratory Services (AASHTO Accredited Laboratory) for full PG Testing according to Superpave PG Asphalt Binder Grade according to the following AASHTO approved test procedures:

[00077] Rotational Viscosity at 135°C by ASTM D4402.

[00084] V67-22 is Valero Refinery Base Asphalt binder produced as such without any modification and graded PG 67-22.SBS RADIAL PLUS "Star" or Radial configuration of the SBS polmer., and was produced as follows:

[00085] 792 g of a mixture of 25% oxidized tall oil and 75% base asphalt PG 67-22 was paced into a quart can and placed in a heating mantle and the temperature raised to 380F while mixing under a Silverson Mixer at 3,000 rpm and under low shear. When the temperature reached 380F, 8g radial SBS (1%) in powder form was slowly added and the temperature maintained at 380F for 60 minutes. 0.3% by weight of the laboratory batch (ie. 0.3% on 800g = 2.4g) cross-linking (commercial Reactibond) agent was added slowly and the temperature and mixing maintained for further 30 minutes. After this time elapsed, the sample was removed from the mixer and cooled to room temperature and sent to Dongre Laboratory Services for testing.

[00086] The sample referenced "E76-22" is standard Polymer Modified Asphalt (PMA) produced by Ergon Refineries in Mississippi, USA and the meets the Superpave PG Asphalt Binder Grade.

[00087] E76-22 is polymer modified (ie SBS) version of asphalt that meets PG 76-22 grade. [00088] PMA is Polymer Modified Asphalt. [00089] TOC is Tall Oil Component.
