摘要： In a system and method for processing recycled asphalt pavement or aggregate for asphalt production, a heating and drying unit includes a trough positioned within an external housing. A hollow auger is positioned in the trough, such that the recycled asphalt pavement or aggregate received at a first end of the trough is transported to a second end of the trough via rotation of the hollow auger. The trough is constructed of two or more sections to allow for thermal expansion, with only one end of each of the two or more sections connected to the external housing. Heated air is introduced into the trough via an inlet and exits the trough via an outlet. Heated oil is pumped through the hollow auger, entering via an inlet and exiting via an outlet. The heated air and heated oil raise the temperature of the recycled asphalt pavement or aggregate.

摘要： A method for producing asphalt using a high percentage of RAP (recycled asphalt pavement) in the total aggregate raw material. A counterflow rotary drum dryer is used to dry the raw material. The extent of the burner flame in the dryer is limited such that the RAP does not come into direct contact with the flame. The hot gases leaving the dryer pass to a wet scrubber.

摘要： A system for producing hot mix asphalt includes a generator having an exhaust port; a dryer drum having an inlet; a duct connecting the exhaust port to the inlet, the duct conveying a first flow of hot gas from the exhaust port; an exhaust bypass vent conveying a second flow of hot gas diverging from the first flow of hot gas; and a valve disposed at a junction between the duct and the exhaust bypass vent for adjusting a flow rate of the second flow of hot gas. The dryer drum produces hot mix asphalt from asphalt materials using a third flow of hot gas diverging from the first flow of hot gas and entering the dryer drum through the inlet.

摘要： A continuous asphalt mixture production plant based on double-horizontal-shaft forced mixing includes a cold aggregate bin, a continuous aggregate conveying and metering system, a drying drum, an aggregate elevator, a double-horizontal-shaft continuous mixing host, a continuous asphalt metering and conveying system, a continuous powder conveying and metering system and a finished product bin. The double-horizontal-shaft continuous mixing host includes a first double-horizontal-shaft mixing cylinder and a second double-horizontal-shaft mixing cylinder connected in series. The first double-horizontal-shaft mixing cylinder is provided with an aggregate inlet, an asphalt inlet, a powder inlet and a first discharging port, and the second double-horizontal-shaft mixing cylinder is provided with a mixture inlet and a second discharging port. The aggregate inlet, the asphalt inlet and the powder inlet are respectively connected with an outlet of the aggregate elevator, the continuous asphalt metering and conveying system and the continuous powder conveying and metering system correspondingly.

摘要： A new and improved method and apparatus for use in conjunction with the free floating paving screed used for road paving is disclosed. The method of forming a bituminous mixture into a smooth flat paved mat comprising some areas with a given nominal mat density and some selected areas with a predeterminedly higher mat density is described wherein problems posed by a reduced compaction ratio occurring subsequently to paving the mat where the roller drum bridges over recesses in the subbase are addressed. The modified paving screed described employs a new adjustable screed plate that allows localized areas of increased angle of attack and a device to increased material entry density in localized areas in front of a screed plate leading edge. Either method is used to create an increase in mat density in the desired area. The method and apparatus teach that by pairing differences in compaction ratio that inherently occur due to subbase irregularities with correspondingly predetermined and different mat densities in the paved mat, a good consistent final density can be achieved notwithstanding the limitations of the compaction rolling. A forward looking vision system is described that identifies subbase recesses, a digital controller quantifies the density increase required, and a GPS system maps locations where the mat density increases are to be applied.
