M-Pack™ Relocatable Asphalt Plants

The innovative Astec M-Pack™ Asphalt Plant sets up much faster and for much less money than stationary plants.

When you don’t need to move often, but still want to reap the benefits of faster and more economical setup, the Astec M-Pack is engineered as a set of modules that are transported by truck and bolted up at the site. Astec tests each component before shipping it to your site to ensure a hassle-free setup. Plus, the M-Pack asphalt mixing plant has full-size control rooms, large silos, high production capacity, and excellent maintenance access.

High production, large storage capacity and high-quality components make the modular M-Pack asphalt mixing plant highly functional. This reliable and durable HMA/WMA plant is outfitted with the latest technology and proven Astec performance. Plus, with any Astec product you get unbeatable customer service and support.

There are a wide range of options on these robust, versatile plants. With a team of experienced engineers and in-house technicians, Astec has the knowledge and the expertise to help you make the appropriate selections to meet your requirements.


Quick setup of durable equipment makes the Astec relocatable facility an excellent value. An M-Pack plant has the capacity and size of a permanent facility with reduced setup costs. That’s a big advantage. Each M-Pack asphalt mixing plant ships in separate loads. 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.

Astec Portable Control Center On Truck

Up And Running In Six Weeks

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

Astec-Heavy Duty Foundations


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, 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.

Astec Pre-Wires and Pre-Pipes Components


Pre-assembly of parts and components saves setup time. Bags are pre-installed in the baghouse to save time and money. Pre-wired and equipped control houses minimize start-up problems because plant controls have been tested at the factory. For easy access, power panels are centrally located to plant components. Tray-rated cables connect motors and power panels. Cable trays hold the cables and keep them organized and off the ground. These are just some of the ways in which Astec makes sure setup and start-up of your new M-Pack goes smoothly.


Astec supplies a complete line of high-performance drying and mixing equipment to fill the varying needs of producers worldwide. Each drum efficiently incorporates RAP into high quality mixes while meeting emissions requirements. Heavy-duty construction and proven wear materials ensure consistent performance year after year.

An M-Pack drum includes solid-built steel foundations that eliminate the need for concrete foundations, making setup faster and easier.

After asphalt paving mix has been produced it is transported to a silo or silos to be batched into waiting trucks or stored for sale at a later time. Silo storage brings the economies of long production runs to the asphalt mixing industry. Both long-term and short-term storage options are available depending on requirements at your plant. Guaranteed four-day storage for unmodified mix.

Only Astec provides a choice of two distinct baghouse styles. Modular construction and built-in supports eliminate the need for concrete foundations, making setup of the relocatable baghouse fast and easy.

  • Astec Pulse Jet Baghouse Learn More

    Pulse Jet Baghouse

    With pulse jet cleaning, no bags have to be taken out of service for cleaning. During cleaning mode, blowpipes direct bursts of compressed air into two rows of bags at a time. The shock and momentary back-flow produced by the compressed air pulse causes the bags in the section to expand and expel the collected dust from the surface, allowing it to drop into the hopper.

    The relocatable pulse jet baghouse, with primary collector modules, is delivered on steel plate foundations. At the site, the top weldment bolts to the hopper section. Filter bag modules are installed on top, and an airtight seal is created between top and bottom sections. Epoxy coating of the interior stops corrosion. Exhaust fan inlet duct, fan base and stack are pre-assembled and fitted to the baghouse. Constructed with AR-400 abrasion resistant steel at elbows. Pulse valves are mounted internally to promote consistent performance by preventing freeze-up. Capacities start at 34,000 cfm, depending on the plant.

  • Astec Reverse Pulse Baghouse Learn More

    Reverse Pulse Baghouse

    Reverse pulse baghouses utilize a damper and a rotating to turret force air directly into the bag filters opposite the normal flow direction. Cleaning is accomplished by isolating a single section of filter bags then reversing the flow of air through them causing a gentle expansion. Accumulated dust dislodges from the bag filters and drops into the hopper beneath. Cleaning sequence and timing is adjustable from the control house.

    Modular in design, the relocatable reverse pulse baghouse can be fitted to your exact size requirements. The relocatable reverse pulse baghouse is available in a range of sizes from 5,000 to over 100,000 ACFM. It is a ruggedly constructed system featuring massive, weight distributing, pyramid style supports that provide a solid foundation. The interior is coated with epoxy paint to stop corrosion. The reverse pulse baghouse is insulated to help reduce condensation inside and to maintain temperature during a hot stop.


Sturdy steel component construction contributes to setup that proceeds quickly and without difficulty. Robust construction ensures years of reliable service.

Dust Run-Around

Weighs all the fine dust, then meters it back into the mix using an automatically controlled VFD air lock. The dust run-around system accounts for all the dust to automatically calculate required AC content.


Stack Temperature Control System

The patented V-Pac stack temperature control system uses v-flights and a drum VFD (Variable Frequency Drive) to help facilitate producing many different types of mixes, while controlling stack temperature, without the added cost and time of drum flight changes.
