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.

A system for metering reinforcing aramid fibers into an asphalt mixer includes a vertical feed chute with straight walls that spans substantially a full diameter and a full length of a horizontal feed auger to feed bulk fibrous material by gravity from the feed chute in a radial direction along the length of the feed auger. The feed auger is rotated at a controlled rate proportionally to the rate of production of an asphalt and mineral aggregate mixture. A pneumatic conveying line conveys the reinforcing fibers from an outlet end of the feed auger to an asphalt mixer for mixing with the asphalt and mineral aggregate to produce a fiber reinforced asphalt concrete with an accurately proportioned amount of fiber dispersed therein.

A highly portable asphalt plant of substantial size and product manufacturing capacity carries the system components on the confines of two transportable vehicles. The two vehicles are arranged in a fashion whereby vehicle one is connected to vehicle two in an inline continuous fashion. Vehicle two contains an integrated inertial dust separator baghouse design and provides for the receiving of the rotary dryer drum mixer directly and without the use, of interconnecting ductwork.

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.

Procedure and plant for the production of tempered bituminous mixtures with reclaimed asphalt pavement (RAP) comprises: a) Provision of RAP having a granulometry comprised between 0 and a maximum diameter; b) Processing said RAP to obtain at least two RAP fractions (one fine, another coarse); c) Subjection of predetermined quantities of said RAP fractions to a process of mixing and heating by hot gas flow such that the heating times of each fraction are adapted to the granulometry thereof, the temperature of the mixture at the end of the step being comprised between 90 C. and 120 C.; d) Blending the mixture with a predetermined quantity of bituminous emulsion supplied at a temperature comprised between 60 C. and 80 C. The temperature of the final mixture will be between 90 and 110 C.

An asphalt plant adapted to use RAP to produce asphalt. The preferred asphalt plant comprises a bin that is adapted to store the RAP, a heat source that is adapted to supply heat, a dryer that is adapted to dry the RAP, a mixer that is adapted the mix the RAP and a means for conveying the RAP from the bin to the dryer. The preferred asphalt plant uses substantially only the RAP to produce asphalt. A method for producing asphalt from RAP comprising providing an asphalt plant adapted to use the RAP to produce asphalt. The preferred method further comprises conveying the RAP from the bin to the dryer, drying the RAP, and mixing the RAP.
