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.

A system for controlling the production of an asphalt mix. The preferred system comprises an asphaltic material source, an asphaltic material sensor, a liquid asphalt cement source, a liquid asphalt cement meter, and a controller. The asphaltic material sensor communicates the amount of asphaltic material liquid asphalt cement and the amount of asphaltic material moisture contained in the amount of asphaltic material to the controller, the liquid asphalt cement meter communicates the amount of liquid asphalt cement provided by the liquid asphalt cement source to the controller, and the controller controls the amount of asphaltic material provided by the asphaltic material source and the amount of the liquid asphalt cement provided by the liquid asphalt cement source. A method comprising controlling the amount of asphaltic material and the amount of liquid asphalt cement provided to the asphalt mix substantially continuously and substantially in real time.

A system and method for filling pot holes. The system includes transferring aggregate from an aggregate tank. Activator is likewise transferred from an activator tank. The activator is mixed with the aggregate to form a homogenized mixture. A liquid is introduced into a homogenized mixture to form a slurry and then a pot hole filler. The pot hole filler is directed through an exit end of a mixing tube.
