How Cold In-Situ Recycling Works
In-Situ Cold Recycling with the CR Series
Cold recycling with integrated paving screed
If required, cement is pre-spread by a STREUMASTER binding agent spreader which is followed by water and binder tank trucks. The milling and mixing rotor of the W 240 CR / W 240 CRi granulates the asphalt layers. At the same time, the cement is mixed in and the water and bitumen emulsion or foamed bitumen are injected into the mixing chamber by injection bars. The processed construction material is conveyed to the rear by the primary conveyor belt and paved true to grade and slope by the VÖGELE paving screed with an integrated spreading auger. HAMM rollers then carry out the final compaction.

The heavy-duty milling and mixing rotor granulates the damaged asphalt pavement. The granulated material is mixed homogeneously in the mixing chamber with spray-injected binder and water to produce a new mixed construction material locally, i.e., on-site.
The spiral-shaped construction of the milling and mixing rotor then conveys the mixed material to the middle and then via the primary conveyor to the installation aggregate. The spreading auger distributes it evenly in front of the variable paving screed, which ensures that the mix is paved true to grade and slope.
Cold recycling with integrated rear loading
If required, cement is pre-spread by a STREUMASTER binding agent spreader which is followed by water and binder tank trucks. The milling and mixing rotor granulates the asphalt layers. At the same time, the cement is mixed in and the water and bitumen emulsion or foamed bitumen are injected into the mixing chamber by injection bars. The processed construction material is conveyed via the belt unit directly into the material hopper of the VÖGELE asphalt paver, which then paves it. HAMM rollers then carry out the final compaction.
Material processing with the W 380 CR / W 380 CRi (downcut)
The heavy-duty milling and mixing rotor granulates the damaged asphalt pavement. The granulated material is mixed homogeneously in the mixing chamber with spray-injected binder and water to produce a new mixed construction material locally, i.e., on-site.
The spiral-shaped construction of the milling and mixing rotor then conveys the mixed material to the middle and then via the primary conveyor and the discharge conveyor to the material hopper of the asphalt paver. The paver then paves the mix true to grade and slope
