Operating principle remixer
A modern remixer - here`s how it works
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
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.
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.
