Wirtgen debuts tracked cold recycler at CONEXPO-CON/AGG 2020

The Wirtgen W 380 CRi made its North American debut at CONEXPO-CON/AGG 2020, set up as a recycling train with the Vögele SUPER 2000 - 3i paver, the Hamm AB 600 TV+ extending screed and the Hamm HD+ 140i VVHF HCQ tandem roller.

With the new generation of cold recyclers, Wirtgen has developed a machine for cold in-place recycling. The tracked recyclers also deliver optimal results during full-depth recycling and high-performance milling.

Full-depth recycling in a single pass

The asphalt surface is removed 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 300 mm/12 in., so it is also suitable for full-depth recycling (FDR).

The W 380 CRi can also restore road surfaces beyond the available working widths of 3,200 mm/10 ft. 6 in., 3,500 mm/11 ft. 6 in. and 3,800 mm/12 ft. 6 in. In this case, the recycler picks up the material that was pre-milled on the side by a cold milling machine and adds it to the mixing process. Thanks to a mixing capacity of 800 t/h / 787.2 US t/h in combination with rear loading onto a road paver with the appropriate stockpiling and paving screed, even very wide road surfaces can be rehabilitated in a single pass.

W 380 CRi doubles as a milling machine

The W 380 CRi can also be used as high-performance milling machine. Thanks to its high engine power of 1,054 PS/1,038 HP (EU Stage 5/US Tier 4f) and conveyor capacity, the W 380 CRi can manage removal work to a milling depth of 350 mm/14 in. 

This enables large-scale rehabilitation work to be carried out quickly, such as on motorways, runways at airports, or the removal of complete asphalt packages, as well as the homogenization and granulation of damaged asphalt layers.
