ABSTRACT:
This invention relates to rapid set, medium set, and slow set anionic emulsions prepared from straight bitumen or bitumen modified by the incorporation of polymers such as styrene butadiene rubbers (SBR), styrene block copolymers (SBS), ethylene vinyl acetate copolymers (EVA), and other suitable modifiers. The invention also relates to emulsions modified by the incorporation of solvents (such as diesel oil or kerosene) or by the addition of polymer latices (such as SBR-latex or natural rubber latex). More particularly, the invention relates to improved methods for enhancing adhesion between asphalt and aggregate in anionic solventless and solvent-containing bituminous emulsions wherein the emulsifiers are alkali earth salts of tall oil fatty acids, fortified tall oil fatty acids, tall oil rosins, and fortified rosins as well as combinations of kraft lignins and nonionic emulsifiers. The adhesion promoting compositions utilized in these improved methods are produced by reacting tall oil fatty acid and/or modified tall oil fatty acid to yield a polyalkylene amine, then blending the polyamidoamine with Bis-hexamethylenetriamine to produce the adhesion promoter.
