Abstract: Embodiments of the present invention relate to systems and methods implemented in a pothole patching system for creating a vacuum that pulls heavy particulate, such as gravel, out of a hopper. For example, according to an embodiment, a vacuum body having a vacuum chamber formed therein is positioned proximate to an opening of the hopper. A moveable slide gate is provided between the vacuum chamber and the opening of the hopper. The slide gate moves between open and closed positions for permitting and blocking communication between the vacuum chamber and the hopper. A reduction nozzle is provided between an air source and the vacuum chamber. Forced air flows from the air source, through the reduction nozzle, and into the vacuum chamber. The reduction nozzle reduces the pressure of the forced air entering the vacuum chamber, and thereby creates a vacuum in the vacuum chamber. When the slide gate is in the open position, this vacuum pulls particulate from the hopper.

Abstract: A mobile asphalt production machine mixes bituminous concrete at the job site through a mixing auger mechanism mounted in an insulated housing. Propane burners provide heat within the mixing auger mechanism and within the insulated housing to produce a hot-mix bituminous concrete in large or small batches. The components of the asphalt mixture are stored in separate bins that can be re-filled at the job site to provide a continuous supply of asphalt. Hot liquid bitumen is added to heated aggregate within the mixing auger mechanism. Recycled asphalt can be added through a port in the mixing auger for incorporation into the mixture. Controls permit the rate of flow of each individual component to be selectively varied in order to change the recipe for the mixture and to provide calibration of the component, while a master control will maintain the pre-established flow rates through a variable speed of operation.
