Operating principle remixer

A modern remixer - here`s how it works

  1. Operator's platform

    Walk-through operator’s platform with controls arranged within easy reach for easy operation.

    Additional Information

  2. Belt conveyor

    Heavy-duty scraper conveyor to forward and add virgin mix to the recycling process.

  3. Gas tanks

    Liquid-gas twin-tank system with filling level indicator to ensure energy supply to the infrared radiators.

  4. Power unit

    Fuel-efficient, powerful diesel engine for high drive power.

  5. Scarifier shafts

    Scarifier shafts adjustable to the specified working width and fitted with carbide tools for gentle scarification of the pavement material.

    Additional Information

  6. Paving screed

    Tried-and-tested VÖGELE paving screed including spreading auger and hydraulic tamping and vibrating unit for perfect paving results.

    Additional Information

  7. Heating system

    Infrared radiator elements adjustable to the specified working width for effective heating of the surface course and underlying base.

    Additional Information

  8. Receiving hopper

    Large hopper to receive virgin mix from the truck.

  9. Binder tank

    Heated binder tank for the storage of bituminous binding agents.

  10. Twin-shaft compulsory mixer

    Heated mixer with high-strength internal lining to ensure homogeneous mixing of the scarified asphalt pavement, binder and virgin material.

  11. Metering bin

    Storage container for continuously adjustable discharge of virgin mix onto the belt conveyor

Hot recyclers are eminently suitable for rehabilitating surface courses within extremely short periods of time. The method is suitable for use with all asphalt pavements, whether motorway or urban road.

Remix or Remix Plus

State-of-the-art operation to create premium road pavements

Remix process

The Remixer 4500 and a panel heating machine travelling immediately ahead heat up the asphalt surface course by means of high-performance heaters. In the next step, rotating scarifier shafts gently scarify the pavement while an accurately metered amount of binding agent is injected at the same time. The scarified material is removed by scraper blades. Tools arranged on the scarifier shafts in a helical pattern convey the material into the mixing chamber, where it is subsequently mixed with virgin asphalt material to create a homogeneous mix. The spreading auger then spreads the discharged material evenly on the preheated base. Heating the bituminous base ensures an excellent bond between layers by “hot-in-hot” application. The surface course is then placed and suffi ciently pre-compacted by the integrated paving screed. Final compaction is carried out by rollers.

Remix-Plus process

The Remix-Plus process is similar to the Remix method, the only difference being the application of an additional thin layer of virgin asphalt mix. Virgin material is discharged from the receiving hopper via a belt conveyor and placed on top of the previously remixed material. A second auger positioned downstream of the first auger spreads the new material evenly, followed by a second screed which paves the fresh layer immediately thereafter. A premium-quality special mix may be used for the upper, thin surface course.
