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.
