  • Mix in place mixing grade emulsion for asphalt or bitumen applications
    Patent number: 9856377
    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.
