Abstract: Application of lecithin-based oil compositions to additive particles to control dusting. Without limitation, a method of reducing an amount of dust produced during transfer of additive particles in well operations may comprise providing treated additive particles comprising additive particles and a lecithin based oil composition disposed on a surface of at least portion of the particles. The lecithin -based oil composition may comprise a lecithin and an organic solvent. The method may further comprise mixing components comprising the treated additive particles and a base fluid to provide a treatment fluid. The method may further comprise introducing the treatment fluid into a subterranean formation.

Abstract: Synthetic asphalt and petroleum asphalt modified synthetic asphalt emulsions which contain recycled tire rubber and processes for making the emulsions at temperatures above ambient or room temperature. These emulsions may contain significant quantities of recycled tire rubber and recycled and reclaimed motor oils and fluxes. In addition, aluminum chloride and ferric chloride may be used in clay-in-water solutions to form emulsifying agents for the synthetic asphalt and modified synthetic asphalt mixtures.

Abstract: Liquefied biomass (16) obtained from direct liquefaction and/or fast-pyrolysis is reacted with mixtures of fatty acids (24) in the presence of an oxidizer (28) and with various reactive monomer and polymer additives (46, 48, 50) to create tailored compatibilizer-like bio-additives (34) that are compatible with petroleum asphalts. By judiciously selecting appropriate additives and additional constituent, such as non-reactive (18) and reactive diluents (30), these bio-additives can be tailored to modify low-temperature properties, high-temperature properties, compatibility with aggregate materials, application characteristics, and other properties of petroleum asphalts for paving, roofing and sealing uses.

Abstract: Asphalt emulsions containing emulsifiers comprising alkali metal or ammonium salts of solidified pyrolytic wood tar oil. Resinous compositions useful as asphalt emulsifiers comprising: (a) solidified pyrolytic wood tar oil and salts thereof, and (b) rosins and salts thereof.

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.

Abstract: Solid waste contaminated with cationic metals is remediated with a composition that reduces the mobility of the metals. A recycled product is formed having improved structural properties for possible use as engineered fill such as road base material. Said composition comprising an emulsion of asphalt or tall oil pitch in water and a chemical fixing agent.

Abstract: Asphalt additive compositions are described which comprise (A) a metallic organic strength improving compound and (B) an anti-strip compound. The metal of said metallic organic compound is selected from the group consisting of manganese, cobalt, copper, vanadium, molybdenum, cerium, iron, nickel, lead, zirconium, barium, calcium and zinc. The preferred metal is manganese. The anti-strip compound is designed to reduce water-induced damage to asphalt paving mixtures.
