Disclosed is a continuous and forced asphalt mixing production method, which relates to the technical field of concrete processing and includes the following steps of: heating a cold aggregate to obtain a hot aggregate, hot mixing and/or cold mixing the milled materials to obtain recycled materials; blending the hot aggregate, the recycled materials, the powder materials and the asphalt to obtain a premix; temporarily storing the premix in a pre-stirring storage bin and then stirring the premix in a forced stirring cylinder, temporarily storing the obtained finished product materials in a finished product storage bin; in the finished product material loading area, unloading into a storage tank of a finished product material conveying vehicle.

A rotary mixing system includes a construction machine. The construction machine includes a frame and a plurality of wheels rotatably mounted to the frame. The construction machine also includes a power source mounted on the frame. The construction machine further includes a milling tool rotatably mounted to the frame and adapted to be selectively coupled to the power source. The milling tool is adapted to provide a reclaimed surface on a work surface. The rotary mixing system also includes an auxiliary vehicle adapted to be removably coupled to the construction machine. The auxiliary vehicle includes a chassis and at least one compaction member rotatably mounted to the chassis. The at least one compaction member is adapted to provide a compaction pass on the reclaimed surface.

A baghouse apparatus for removing particulates from a 100% recycled asphalt pavement dryer exhaust air stream includes a drop out zone section having a water spray operable to initially drench an incoming air exhaust stream with water droplets while increasing air stream velocity, then slow the air stream velocity to cause drop out of particulates >1000 m from the slowed waste air stream, and collect the particulates dropped out of the waste air exhaust stream. The apparatus also includes a cyclonic scrubber section for further cooling the waste air exhaust stream while subjected the stream to a further water spray to condense aerosol vapor into droplets, a prefilter filtration section operable to collect and remove condensed aerosol droplets from the waste air stream; and a coalescing filtration section operable to remove 99% of remaining particulates from the waste air stream before discharge of the air stream to atmosphere.

An asphalt processing system is formed from a heating drum and an induction heating system. Flights move asphalt through the heating drum, which concurrently heat the asphalt along with the heating drum wall. A mixing drum can be connected to the heating drum, and include paddles or flights to move the asphalt, while concurrently mixing the material to ensure consistent temperatures through the asphalt cement. The asphalt is heating using one or more induction heating systems to quickly heat the asphalt to between 275 F. and 750 F., followed by moving the asphalt to between 275 F. and 350 F. The system can include a convection system that heats recirculated air through the heating drum. A water condenser can be employed to remove moisture during air recirculation, and reduce asphalt moisture content. The asphalt cement is optionally modified by addition of one or more rejuvenation oils. This system is particularly useful for recycled asphalt pavement, but can be used for all asphalt products.

An apparatus for producing hot mix asphalt from 100% recycled pavement aggregates includes a rotatable inclined drum having a central axis and having a first and second end. A heat source spaced from one of the ends introduces hot gas into the drum via one of the first and second ends. An aggregate supply introduces aggregate into the drum through one of the first and second ends. A RAP collar spaced from the ends and positioned around the drum is used to introduce sand through openings beneath the collar into the drum as the drum is rotated. The RAP collar has an annular heat and smoke shield fastened around the drum for minimizing escape of hot gas from the drum openings beneath the RAP collar. The drum has replaceable buckets within the openings for receiving, holding and distributing sand into the drum as the drum rotates about its axis.

An asphalt production apparatus (APA) (14) and process for utilizing a substantial fraction of RAP (Recycled Asphalt Product) (10) in producing a renewed amalgam (12) for paving. The APA (14) is formed about an inclined central axis (18) and includes core components (16), namely: a non-rotating ignition cylinder (24); a rotating mixing drum (26) having a hollow interior (16) with radially spaced combustion tubes (52) longitudinally extending therethrough; and a stationary capture trap (28) for receiving renewed amalgam (12) and redirecting some spent gases (54) back through the a mixing drum (26) in a second pass. The ignition cylinder (24) receives combustion fuel (32) delivered to an igniter (34) and directs flaming gas (36) through the combustion tubes (52) at a flow rate such that the flaming gas (36) becomes spent gases (54) within the tubes (52) short of the capture trap (26) and no flaming gas (36) contacts RAP (10) in the interior of the mixing drum (26).

An exhaust quenching system is provided for use in connection with an asphalt concrete production plant having a dryer for drying aggregate material, an exhaust gas outlet conduit for discharge of exhaust gases from the dryer, and a dust collection assembly that is adapted to receive exhaust gases and entrained dust from the dryer via the exhaust gas outlet conduit. The exhaust quenching system is adapted to effect evaporative cooling of the exhaust gases in the exhaust gas outlet conduit upstream of the dust collection assembly.
