World’s most powerful cold recycler capable of cold in-situ and full-depth recycling, plus high-performance milling
WITH their new generation of cold recyclers, Wirtgen claim to have developed the world’s most modern machines for cold in-situ recycling. The tracked recyclers are also said to deliver impressive results during full-depth recycling and high-performance milling.
An asphalt surface can be removed, depending on the level of damage, by a recycling train operating across the entire width of the pavement in a single pass, mixed with binding agents on site, and then paved again immediately. The W 380 CRi, can recycle the road surface to a full depth of 300mm, so it is also suitable for full-depth recycling (FDR).
The recycler can also restore road surfaces beyond the available working widths of 3,200mm, 3,500mm and 3,800mm. In this case, the W 380 CRi picks up material that has been pre-milled on the side by a cold milling machine and adds it to the mixing process.
Thanks to a mixing capacity of 800 tonnes/h in combination with rear loading on to a road paver with the appropriate stockpiling and paving screed, Wirtgen say even very wide road surfaces can be rehabilitated in a single pass.
The W 380 CRi can also be used as high-performance milling machine. Owing to its 1,054PS (EU Stage 5/US Tier 4f) of engine power and high conveyor capacity, the machine can manage removal work to a milling depth of 350mm.
This allows large-scale rehabilitation work to be carried out quickly, such as on motorways, airport runways, or the removal of complete asphalt packages, as well as the homogenization and granulation of damaged asphalt layers.
