  • Patent number: 11667568
    Abstract: Described are stabilized materials and methods and systems for providing said stabilized materials. The system includes a first unit for mixing a first combination that includes a quantity of drill cuttings and a drying agent. The system may include a second unit for mixing the first combination with at least a binder and/or a surface acting agent and providing a second combination. The second combination is formed when the first combination is caused to have a reduced moisture content, transitioning from a first state to a second state. The reduced moisture content in the second state is at least 20% less than the moisture content of the drill cuttings. The first combination in a second state is a stabilized material. The first combination in a second state may be a dried material. The binder and/or a surface acting agent with or without additional additives are not introduced until the first combination is in the second state.

  • Patent number: 4630965
    Abstract: Apparatus for sealing pavement joints or seams are disclosed. The apparatus includes a wheeled support platform which serves to mount a cylindrical storage container suitable for holding a selected amount of an asphaltic emulsion sealing composition. An applicator is coupled to the bottom of the storage container and controls are provided to selectively vary the volume of the stream of sealing composition and to permit the stream to be completely extinguished. In order to prevent the asphaltic emulsion sealing composition from breaking down or settling out during application an agitator device is provided which propels the sealing composition upward from the bottom of the storage container and mixes the sealing composition. In a preferred embodiment of the present invention the agitator device is gear driven in response to movement of the wheeled support platform.
