Abstract: Crosslink agents dispersible in oil or water for polymer modified asphalt. Sulfur is used in combination with hexamethylenetetramine and other adjuvants to form a powder compound suitable for use as is or dispersed in either oil or water.

Abstract: Emulsions designed for road construction applications. Construction with emulsions and the related process disclosed herein is now possible at ambient temperatures by the unique and unexpected combination of emulsifier(s), surfactant(s) and break control agent(s) to form mixtures of emulsion plus break control agent and aggregates.

Abstract: Asphaltic or bitumen emulsions designed for road construction applications. Construction of full depth pavements with emulsions and the related process disclosed herein is now possible at temperatures below about 160° F. to 180° F. by the unique and unexpected combination of emulsifier(s), surfactant(s) and optional break control agent(s), to form mixtures of emulsion plus break control agent and aggregates. The mixtures of emulsion plus break control agent and aggregates are then spread across the paving area. The spread mixture then breaks, sets and otherwise cures to a complete mass or mat suitable for the intended design application.

Abstract: A vertically moving horizontal mixer assembly which includes a tank having an axis. A stator and blade support assembly is movable parallel to the tank axis. At least one rotatable blade substantially perpendicular to the tank axis is moveable parallel to the tank axis. The rotating blade may be a flat circular disk with raised tooth edges perpendicular to the disk around the circumference of the blade. An optional stator also directs and encourages movement and mixing of solids with liquids.
