Operating Principle of In-Situ Cold Recycling
In-Situ Cold Recycling with the CR Series
Cold Recycling With Built-In Paving Screed
If necessary, a STREUMASTER binding agent spreader pre-spreads the cement, followed by a water tanker and a binding agent tanker. 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 prepared building material is conveyed to the rear via the primary conveyor. The VÖGELE paving screed with spreading auger ensures that paving is carried out true to line and level. HAMM rollers then carry out the final compaction.
Materials Processing With the W 240 CR/W 240 CRi (Down-Cut)
The heavy-duty milling and mixing rotor granulates the damaged asphalt pavement. The granulated material is homogeneously mixed with a binding agent and water sprayed into the mixing chamber to produce the new mix on the spot.
The helical design of the milling and mixing rotor transports the mix to the center and then to the paving unit via the primary conveyor. The spreading auger distributes it evenly in front of the variable paving screed, which ensures that the mix is paved true to line and level.
Cold Recycling with Built-In Rear Loading
If necessary, a STREUMASTER binding agent spreader pre-spreads the cement, followed by a water tanker and a binding agent tanker. 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 material is conveyed via the conveyor unit directly into the VÖGELE asphalt paver’s material hopper, which then paves it. HAMM rollers then carry out the final compaction.
Materials Processing With the W 380 CR/W 380 Cri (Down-Cut)
The heavy-duty milling and mixing rotor granulates the damaged asphalt pavement. The granulated material is homogeneously mixed with a binding agent and water sprayed into the mixing chamber to produce the new mix on the spot.
The helical design of the milling and mixing rotor transports the mix to the center and then to the asphalt paver’s material hopper via the primary conveyor and discharge conveyor. The paver then paves the surface true to line and level.
