Abstract
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.
Claims17
A method of preparing an asphalt mixture comprising a recycled oil component, said method comprising:
- shredding or grinding roofing shingles in a shredder or grinder to yield a pulverized recycled asphalt shingle material, wherein said roofing shingles are reduced to a particle size of less than approximately ⅛″, wherein said pulverized recycled asphalt shingle material comprises an amount of recycled oil;
- delivering said pulverized recycled asphalt shingle material to a mixing drum;
- delivering an aggregate material to said mixing drum;
- and
- optionally, delivering an amount of virgin asphalt oil to said mixing drum;
- thereby producing said asphalt mixture.
