Voyager™ 120 Portable Asphalt Plant
120 MTPH Portable Asphalt Plant
The Voyager 120 offers a compact, highly portable design. Unique for a plant in this class with the ability to run up to 30% RAP. In addition, it is backed by the best service support in the industry.
The ASTEC Voyager 120 is built around a counter flow drum featuring ASTEC v-fights. The v-flights provide greater uniformity of the aggregate veil during the drying process, which results in better heat transfer, a reduction of fuel use and increased productivity.
To enhance portability, a hydraulically driven swing out drag and batcher can be set and ready to go in about 10 minutes. Other features include a reverse pulse baghouse, a controls cab with fully automated PLC controls, gravity take-up with direct drive, air ride suspension and up to five (5) cold feed bins and two (2) RAP bins.

1.) Sloped Bin Walls
The very steep side walls of the bins promote smooth flow of the aggregate and prevent bridging of materials.
3.) Operator's Cab
Operate your plant in a climate controlled cab while using Astec's fully automated PM2 V control system to make your mix. Also available in a stand-alone cab design.
4.) Unidrum® Drum
The 5.5 ft (1.68 meter) counterflow Unidrum drum can produce up to 120 mtph with the addition of 30% recycled material. Astec v-flights come standard and provide greater uniformity of the aggregate veil.
5.) Drag Conveyor and Batcher
The pivoting drag conveyor and batcher attach to the frame during transport. Set the drag in place with a front end loader when it is time to start making mix. For even easier setup, optional hydraulic cylinders are available.

6.) Safety Handrails and Ladder
Safety handrails and ladder come pre-installed for added safety and ease of access. Ladders and handrails fold down for transport mode.
7.) Reverse Pulse Baghouse
17,600 CFM reverse pulse baghouse with 175 Aramid bags. Featuring a streamlined design for ultimate portability.
(not shown in illustration)
The primary collector captures coarse dust as air flows into the baghouse. Since very few coarse particles enter the baghouse, it can collect small fines very efficiently. Removal of coarse fines in the primary collector also reduces wear on the bags.
11.) Air Ride Suspension
Air ride suspension provides a smooth ride and allows for fast setup times by raising and lowering the drum into place.
12.) Dust Return System
Common drives throughout the dust return system simplify maintenance in the field. The fixed system results in fast setup times at the job site.
UNIDRUM® COUNTER FLOW DRUM
Achieving a quality asphalt pavement requires mixing materials correctly, with consideration given to providing sufficient time for blending. The superheated virgin materials must have adequate mixing time to bring it to temperature. The virgin aggregate, recycled asphalt, additives, baghouse fines, and virgin liquid AC must all be blended thoroughly to ensure everything is well coated and the gradation is uniform. The mixing chamber in the Unidrum mixer is an excellent mechanism to ensure adequate blending to achieve a quality mix.
1.) Feeder Flights
Move material into the drying portion of the drum
Feeder flights guide aggregate as it enters the drum, helping it move efficiently toward the v-flights.
Provide greater uniformity of aggregate veiling through the gas stream during the drying process, across a wide variety of mix designs and tonnage rates.
The v-shaped notch allows material to start pouring out of the flights at the beginning of each revolution. The material in the flight continues to pour out until the rotation is complete. This is what provides an even veil of material. The v-flight is also larger than a traditional flight, allowing it to carry the same amount of aggregate even with the notch.
U.S. Patent No. 9,835,374
3.) Combustion Flights
Prevent aggregate from impinging on the flame, while spreading the material to maximize radiant heat transfer.
The combustion flights are made of stainless steel, which lasts longer than traditional carbon steel. The flights overlap one another, creating a shield that minimizes radiant heat from hitting the drum shell, to keep it from overheating. The overlapping also reduces the opportunity for aggregate to get behind the flights and cause additional drum wear.
4.) Recycle Inlet
A collar around the drum allows entry of recycled asphalt (RAP), additives/filler, and baghouse dust into the mixing chamber, where they are blended with the virgin material.
RAP, recycled asphalt shingles (RAS), baghouse dust, and any additive/fillers enter the mixing chamber directly behind the burner nose, minimizing oxidation of the liquid asphalt from the burner flame and allowing preliminary blending before the virgin liquid asphalt is added.
5.) Liquid Asphalt Inlet
Liquid asphalt is injected after the virgin aggregate, the recycled material, and baghouse dust are mixed. Pre-mixing these materials allows a more even distribution of the liquid asphalt cement.
Liquid asphalt is accurately metered from the storage tanks directly to the liquid asphalt inlet inside the mixing zone.
6.) Mixing Flights
After virgin and recycled materials are combined and brought up to the proper temperature, liquid asphalt is injected. Mixing flights provide increased agitation for improved mix quality.
Unidrum mixing flights are engineered to comb through virgin and recycled materials to provide thorough blending before the mix exits the drum. The mixing flights are reversible to enhance mix coating if necessary.
Fury™ 35 Burner
Astec's Fury™ burner provides a robust build and simple, accessible construction. Compared to other open-fired designs, the Fury™ burner achieves better emissions and fuel-efficiency by putting 50% more combustion air through the burner.
