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 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 system and method for monitoring and adjusting a constant flow asphalt manufacturing process includes monitoring the ratios of recycled material to virgin material to minimize costs and adjusting the mixture in real time. Pulverized asphalt shingle (PAS) material may be used as a source of recycled asphalt oil and fed to a mixing drum with real-time monitoring while making real-time adjustments to supplement the asphalt with new asphalt oil to the mixer. The systems and methods may also be used for monitoring, metering, and supplementing recycled aggregate from recycled asphalt pavement (RAP) with new aggregate. The systems and methods may use one or more processors or programmable logic controllers (PLC) to meter the addition of new materials.

摘要： A method of making hot mix asphalt using recycled asphalt in which tertiary air is mixed with products of combustion at an exit of a refractory-lined chamber to produce hot controlled temperature process air, the temperature of the tertiary air being increased while the temperature of the products of combustion is decreased to adjust a temperature of the hot controlled temperature process air. Particles of the recycled asphalt are heated by exposing the particles to the hot controlled temperature process air in the rotary counter-flow dryer and mixer and moisture is removed from the recycled asphalt with the hot controlled temperature process air.

摘要： Asphalt mix product is produced for delivery at a desired temperature and is comprised of a mixture of recycled asphalt product and virgin material in a specified, selected proportion of recycled asphalt product to virgin material. Recycled asphalt product is heated in an indirectly heated recycled asphalt product heater to an elevated temperature. Virgin material is heated in a heater to a maximum temperature not exceeding a prescribed temperature above which damage to that heater will occur. The heated recycled asphalt product is mixed with the heated virgin material in the selected proportion of recycled asphalt product to virgin material to prepare the asphalt mix product for delivery at the desired temperature. By virtue of heating the recycled asphalt product and mixing the heated recycled asphalt product with the heated virgin material, the selected proportion of recycled asphalt product to virgin material is not limited by the maximum temperature of the heated virgin material, and asphalt mix product is produced effectively and economically with proportions of recycled asphalt product to virgin material which are considerably higher than heretofore available.

摘要： A system to prevent accidental discharge of hot-mix asphalt at asphalt plants with multiple silos includes a closed circuit TV camera and a system of flashing lights. The TV camera has a fixed view of the loading area with a monitor at the control panel. When hot-mix asphalt is to be discharged into a truck, a switch is activated which causes a light beneath the bin to flash. This identifies the bin selected to open. The TV monitor is viewed and the position of the truck can now be visually confirmed along with the flashing light on the bin that has been activated. A second button must be pushed in order to complete the discharge of the hot-mix asphalt from the bin. Ideally, the second button is located either on the monitor or as close to it as possible in order to force the viewing of the screen before activating the second switch.

摘要： An apparatus and process is provided for the production of hot mix asphalt (HMA) by the treatment of virgin material alone or adding reclaimed or recycled asphalt pavement (RAP) of up to 100% of the HMA comprised of reclaimed asphaltic pavement (RAP). The HMA is first heated in either a parallel or a counter flow rotating drum which is supplied with hot combustion gases generated by a remote low NO.sub.x burner. The temperature of hot gases entering the drum is from about 400.degree. to 2,000.degree. F., and the temperature of gases exiting from the drum is from about 130.degree. to 220.degree. F. The HMA material optionally can be subjected to microwave radiation to raise the material to a final temperature, or optionally to only reorient the dipolar molecules of the material without any measurable heating of the material. The exhaust gas is treated and made environmentally safe. The hot gases exiting from the drum are passed through a knockout box and then through a baghouse having acrylic bags coated with a protective layer of particulate material. The gases exiting the baghouse are passed through an oxidizer to further remove smoke and asphaltic material and at least a portion of the gases from the oxidizer are recycled through a heat exchanger.

摘要： An apparatus for controlling the angular velocity and slope angle of a hot mix asphalt drum as a function of the temperature gradient across the drum outlet. Uneven gas outlet temperature indicates that the veil of RAP (Recycled Asphalt Pavement) in the drum is insufficient. The veil is increased by increasing drum speed. The complete recycled asphalt pavement hot mix asphalt plant uses uneven gas outlet temperatures to change drum operating parameters.
