    • Each M-Pack plant ships in complete loads.

      Up And Running In Six Weeks

      You can set up an M-Pack plant on a prepared site in about six weeks, at less than half the cost of erecting a stationary plant of comparable size. Each Astec M-Pack plant ships in complete, ready to set up loads when it leaves the manufacturing facility.

    • Heavy-duty construction of components withstands the aggressive environment of an asphalt plant.

      Preserve Value

      Astec equipment costs less to run and maintain than other plants because we use substantial components that stand up to heavy use. That is also the reason for Astec's consistently high resale value. Even for plants that are 10 to 15 years old average residual value is 68% of your original investment. Plus, Astec sets up every facility before shipping to ensure setup ease at your site.


      Get A Handle On Setup Costs

      For complete setup cost control, Astec can erect your new plant for you. You will know up front what all costs will be and won't have to concern yourself with estimates from electricians, welders, fitters, etc.


      Choice Of Tonnage Capacities

      M-Pack plants come in a range of capacities from 200 to 600 tons per hour. Choose the production capacity you need and we will help you design, construct, and start up your new M-Pack plant.

    • Direct drive motors on the cold feed ensure strong performance and eliminate belts, guards and pulleys.

      Direct Drive Cold Feed Motors

      Astec uses variable frequency direct drive motors on the cold feed system. You will have less maintenance to worry about since a gear box runs the belt feed drive without the need for more belts or sheaves.

    • Optional ceramic liners protect the silo cone.

      Optional - Ceramic Silo Liners

      Ceramic liners are available for the cone, spool and batcher. Ceramic protects vulnerable parts of the silo against excessive wear from the abrasive asphalt mix.

    Save Time During Setup

    Level and pave your site. Then lift the pre-piped, pre-wired modules off the trailer. Sturdy steel construction ensures that setup proceeds quickly and without difficulty.
    • Cable trays on each component neatly keep power and control cables off the ground.

      Pre-piping and Pre-wiring

      Astec mounts, pre-wires and pre-pipes all related components. For easy access, power panels are located in either a separate power room or in the lower level of the control center. CT-Rated cable with UV rating* connects motors and power panels. Cable trays hold the cables and keep them organized and off the ground.

      Pre-assembly of parts and components saves setup time. Pre-installed baghouse components are a huge time saver. Fully pre-wired and equipped control houses minimize start-up problems because plant controls have been tested at the factory. These are just some of the ways in which Astec makes sure erection and start-up of your new M-Pack goes smoothly.

    • Wing walls on the cold feed bins eliminate the need for an additional concrete structure.

      Bulkheads And Wing Walls

      Save the expense of constructing retaining walls for loader ramps.

      The cold feed bin and the recycle bin both come with full-length bulkheads that extend all the way from the top edge of the bin to the ground. Wing walls swing out to retain the sides of loader ramps.

      ASTEC bulkheads are 3/16" thick and braced with structural tubing to protect equipment from damage by loaders. They also keep dirt and debris out of cold feed and recycle bin mechanisms. A walkway in-between the bulkhead and collecting conveyors provides access to the back of the bins and conveyors for maintenance.

    • Astec supplies ladders and handrails for all components.

      Ladders, Handrails and Platforms

      Astec supplies the stairs and caged ladders required to access components for inspection or maintenance. OSHA compliant hand-rails around platforms and along drag conveyor stairs help keep workers safe.

    • Maintenance is easier with a walkway between the bulkhead and the collecting conveyor.

      Designed with Maintenance in Mind

      ASTEC incorporated features to make the necessary task of performing maintenance easier.

    A Range of Options and Components

    • Full length access doors on the Double Barrel drum make routine maintenance easier.

      Double Barrel® Drum Mixer

      Two main modules make up the relocatable Double Barrel: the foundation frame, which includes the bottom of the mixing chamber, and the inner drying drum. The foundation frame is set off, then the drying drum is positioned. The top of the mixing chamber is raised into place and connected to the lower section. Attaching the full length access door completes the mixing chamber. Last, the burner is installed, along with the virgin inlet breaching and the fines and recycle inlets.

    • The patent pending Double Barrel Green System allows you to cut fuel consumption significantly.

      Optional Double Barrel Green™ System

      The latest innovation from Astec saves energy and eliminates smoke and emissions without compromising mix quality. The optional Double Barrel Green System uses water to produce a foamed warm mix asphalt that is odorless, smokeless and longer lasting.

    • Astec drag conveyors are shipped completely assembled.

      Drag Conveyor

      Astec HMA storage systems fit any size storage need. The silos feature A steep 66° cone angle which provides segregation-free loadout through mass flow. Astec silos also feature better insulation than competitor's models, so they have the ability to store product for four days without loss of mix quality.

    • Sturdy construction withstands the tough environment of a hot mix asphalt facility.

      Storage Silos

      Depending on the size of the silo, legs and batchers are mounted to the silos at the site. Plates at the bottom of the silo legs attach to anchors set in concrete. The drag conveyor comes completely assembled except for the top service platform, which is installed on-site. The conveyor is then raised and attached at the top of the silos. Weld plates set in concrete stabilize the bottom of the drag conveyor.

    • Optional additive silos are used to hold a variety of mix additives.

      The Additive System And Fines Silo

      Silos for fines, mineral fillers and other dry additives come in a range of sizes and with a number of metering options. Plates at the bottom of silo legs are embedded in concrete to stabilize these tall structures.

    • Separate RAP into two sizes for more efficient use.

      Rap Bins And Rap Conveyor

      The Reclaimed Asphalt Pavement (RAP) bins ship as a single module including a skid foundation. An upturned end attaches to its collecting conveyor and goes to the scalping screen of the RAP conveyor. The standard system comes with one bin, with additional bins offered as an option. A separate RAP conveyor with scalping screen is included in the standard system. An optional closed loop RAP crusher system is also available.

    • As dust spirals through the cyclone, the heavier dust particles are collected.

      Pulse Jet Baghouse

      The pulse jet baghouse with primary collector modules ship with foundations in place. Filter bag modules are installed on top, and an airtight seal is created between top and bottom sections. Exhaust fan inlet duct, fan base and stack are pre-assembled and fitted to the baghouse. Elbows lined with abrasion resistant steel guarantee collection efficiency. Pulse valves are mounted internally to promote consistent performance by preventing freeze-up. M-Pack baghouse capacities start at 34,000 cfm, depending on the plant.

    • The coarsest dust particles collect in the inertial separator before the air passes through the pulse jet baghouse.

      Primary Collectors

      Heavy, coarse dust particles collect in a primary collector before the air passes through the baghouse. Astec offers a choice of primary collectors: either an inertial separator or a cyclone.

    • Built-in, heavy-duty foundations speed setup.


      The M-Pack foundations are heavy-duty. They provide plenty of load-bearing surface to support the facility components.

      The cold feed unit, recycle bins, Double Barrel® drum mixer and baghouse have thick structural tubes under each module leg. Steel skid foundations are used under the exhaust stack end of the baghouse. The scalping screen is supported by skid-type foundations.

      If you ever have to move to another site, most loads fit on lowboy type trailers, and the built-in foundations go with them.

    • A fiberbed filter unit captures emissions before they escape into the atmosphere.
