      Compact RAP System

      A compact RAP System is easy to relocate when it is time to move. The portable RAP system includes everything for metering recycled material into the mix. The system includes belt feeders, the collecting conveyor with weigh bridge, the scalping screen, the inclined conveyor to the drum, and up to four bins.

    The Astec Six Pack Facility Can Be Set Up And Operational In Minimal Time.

    And it can also be designed so a crane is unnecessary for set up.
    • Ladders, stairs, platforms and handrails are shipped in place.

      Pre-Assembly Is A Real Time Saver

      Astec pre-assembly significantly reduces the number of hours it takes for setup. Most ladders, stairs, platforms and handrails are shipped in place. Bulkheads are pre-installed. Pre-piping and pre-wiring done at the factory cut many hours of work every time you move. Factory-installed baghouse filter bags with cages save your people from the cumbersome, time-consuming chore of installing this system themselves. Other conveniences include the scalping screen pre-installed on the inclined conveyor and the mounted and pre-wired operating consoles in the control house.

    • The drum is raised to operating position by a hydraulic unit provided.

      Easy Elevating, Leveling & Stabilizing

      Once they are positioned, pre-level all Astec units using the air bag suspensions. Crank-down landing gears support the loads after unhooking from the tractor and before lowering the steel foundations. Final elevating and leveling is done with built-in hydraulic or mechanical jacks. Astec duct work and piping even allows for small alignment variations. You don't have to deal with shims or concrete foundations for any part of the Six Pack HMA facility.

    • Astec engineers designed the Six Pack HMA facility foundations for setup ease.

      Compare Our Foundations

      Foundations ship in place and are quickly lowered to support the equipment on compacted soil. The built-in, retractable steel foundations significantly reduce the work required to set up or break down the Six Pack facility. Even the best foundations on competitive equipment are usually crude and difficult to adjust and often require use of timbers for leveling and to increase the load bearing surface. You'll never have those problems with the Six Pack HMA facility.

    Component Design Makes Setup Easy

    The Double Barrel® drum mixer, cold feed, recycle, conveyor, baghouse, SEB and additive systems each move as complete loads.
    • One load contains the complete cold feed unit.

      The Cold Feed Unit

      Pull the cold feed unit into position at the site. Lower the thick tubular steel foundations into place to support the portable cold feed unit. All belt feeders and the collecting conveyor are included. The upturned end of the collecting conveyor discharges onto A transfer conveyor feeding screen. Built-in, hinged bulkheads swing into operating position in minutes. Pre-installed, optional bin partitions and grizzlies fold down for transport.

    • One single load includes the transfer conveyor, screen, scalping screen and weigh bridge.

      The Virgin Inclined Conveyor/Screen

      This unit comes with the transfer conveyor to screen, scalping screen and weigh bridge, all mounted on a single load. Hydraulics raise the conveyor, screen and chutes into operating position. The screen is supported by the main frame to isolate the weigh bridge from screen motion.

    • Optional two bin rap system allows increased RAP usage with quality results.

      The Rap Bins

      The portable RAP system includes everything for metering recycled material into the mix. The system includes belt feeders, the collecting conveyor with weigh bridge, the scalping screen, the inclined conveyor to the drum, and up to four bins. The foundation plates are lowered into position and the conveyor is raised hydraulically. Just like the cold feed unit, the RAP system is equipped with built-in tubular steel foundations and bulkheads.

    • Run higher percentages of RAP without increasing fuel consumption.

      The Double Barrel Drum Mixer® Drum Mixer

      The Double Barrel load includes the burner, burner platform, inlet breaching and the duct transition to the primary collector. Plate foundations support the load. Built-in jacks make final leveling adjustments easy, so the Six Pack facility can start running sooner.

    • The low profile design of the baghouse makes traveling easy.

      The Express Baghouse

      Two low profile hoppers lower the baghouse profile and let you pass under power lines, bridges and overpasses without any trouble. The unit is supplied complete with exhaust fan, stack, and duct. The Express Baghouse is provided with an inertial dust collector. A separate cyclone is available as an option.

    • The SEB combines several operations into a single unit: conveying, batching, surging, storage, truck weighing and loading.

      The SEB (Self-Erecting Surge Bin)

      The SEB reduces the number of loads by combining four functions in one load: conveying, batching, weighing and storage. A thick, steel truck loading platform is part of the frame (competing bins usually need expensive concrete foundations). You also get a drag by-pass chute with a built-in bulkhead. Two large hydraulic cylinders raise the SEB into position in less than 15 minutes.

    • The portable additive silo stores lime, mineral filler, of baghouse fines until required by a mix.

      The Additive Systems

      If you use lime in your mixes, or if you need a storage device for baghouse fines, the Astec portable additive silo is your mobile solution. Systems with or without slurry systems come on a self-supporting frame and include a screw conveyor and metering device. Choose an optional hydraulic system to erect the silo easily.

    The Six Pack HMA Facility Simplifies Electrical Hookup

    The remarkably efficient design includes pre-wiring in conduit, short cable runs and plug-in connections.
    • Easy setup. Plugs connect quickly to panels.

      Electrical Connections

      All of the motors and electrical components come pre-wired from the factory. The baghouse exhaust fan, screws and air compressor arrive wired directly to the main power panel.

    • Cable trays neatly keep power and control cables off the ground.

      Prewiring keeps the plant neat

      The drag conveyor motor wiring runs in conduit to the main power panel. Wiring to cold feed, RAP system, heaters and tanks is routed from the main power panel to a panel on each component. Cables simply plug into those panels. The power panels* are sealed and dust-tight. Control wiring for the cold feed bins and the burner require only a short cable to the junction box on the surge bin frame. These connections are also plug-in type. The control house is pre-wired in conduit to the junction box. Cable trays neatly keep power and control cables off the ground.

      * all panels are rated NEMA 3R

    • The control house is pre-wired for quick setup and can be placed for ease of ticket delivery.

      Portable Control House

      The control house contains the nerve center for the entire asphalt plant. The control house frame can be picked up by crane without danger of warpage due to all-steel welded construction. Control centers are furnished with central heat and air, insulated floors, walls and ceilings. Acoustic ceiling tiles reduce noise in the house. Tinted windows and fluorescent overhead lighting provide superior visibility. A built in ticket window is standard. Provides an excellent facility control environment and surveillance capabilities with convenience and comfort. All controls are factory installed and fully tested prior to delivery.

    • A centrally located main power panel and junction box keep cable runs short.

      Short Cable Trays Are Easy To Handle

      We locate the main power panel and the junction box for control house wiring in the middle of the plant. This central location for the panels keeps cable runs short. The Six Pack facility has less than forty thermoplastic elastomer covered cables, which makes for fast electrical hook-up and quick packing when moving to another site. Cable trays are fitted to each load, keeping cables organized and off the ground.

      Unplugging and rolling up cables, A process which can take up to A full day on competitors' portable plants, can be done in about two hours with the Six Pack HMA plant. The control house is pre-wired for quick setup and can be placed for ease of ticket delivery.

    The Six Pack HMA Plant Is Full Of Features

    The SEB eliminates the need for truck scales with load cells.
    • There is no need to construct separate retaining walls. Built-in bulkheads protect machinery.

      Built-in Bulkheads

      Save yourself the construction of separate retaining walls for loader ramps. The Six Pack plant features built-in steel bulkheads on cold feed bins and RAP bins. Bulkheads also protect your machinery from damage by loaders and they keep dirt out of belt and drive mechanisms and away from wheels and brakes.

    • You'll never find plywood on Astec equipment. Bulkheads are constructed of steel.

      Built for transport

      For transport, the hinged walls are quickly folded up and pinned off. You won't have to put together the cumbersome "guardrail" type walls used on some other plants, and you won't find any plywood bulkheads on Astec equipment. An additional bulkhead is located at the bottom of the drag conveyor by-pass chute. It makes it easier to remove accumulated material with a loader and to keep the drag by-pass area clean.

    • Load cells ensure that hot mix asphalt is dispensed accurately.

      Load Cells

      Astec uses a precise, National Type Evaluation Program (NTEP) approved silo weighing system. Load cells at each corner of the SEB accurately weigh the mix, eliminating the need for truck scales.

    • Add optional portable Heatec asphalt tanks for reliability.

      Heatec Tanks

      Optional portable style Heatec Heli-Tank™ units combine a hot oil heater with a heated asphalt storage tank. Each fully insulated unit has serpentine heating coils. Liquid asphalt in the tank is heated by hot oil flowing through the coils. Numerous options are available.
