The powerful unit for effective soil stabilisation

  • The WS 250 tractor-towed stabilizer is designed for efficient soil stabilization at a working width of 8' 2" (2.5 m).
  • Its range of applications includes measures for both soil improvement and soil consolidation.
  • During soil improvement, the tractor-towed stabilizers produce soil that can be easily paved and compacted for embankments, slopes, backfilling, or construction site transport routes.
  • During soil consolidation, they create surfaces with sufficient bearing capacity for the construction of parking lots, roads, sports fields, railroad tracks, port facilities, airports, and or industrial areas.

Soil stabilization with tractor-towed stabilizers

Whether heavy, coarse-grained, or sandy, the tractor-towed stabilizer reliably transforms the sub-base into a surface with excellent paving and compacting properties. Mixed granulate that is too coarse is crushed in the mixing chamber by the milling and mixing rotor. Soft soil is covered with lime, e.g. by a spreader truck, before processing. During the subsequent, homogeneous mixing process using the milling and mixing rotor, the lime removes the moisture from the soil.

The recipe for increasing long-term stability in the face of traffic and weather conditions is to strengthen the soil by adding binding agents such as cement. The result of soil stabilization is a rigid surface with a permanently high bearing capacity as well as excellent frost resistance.

Mixing procedures

Cold recycling can either be carried out in-plant by transporting the material recovered from an existing road to a central warehouse and passing it through a mixing plant, or in-place/in-situ using a cold recycler.

In the in-place/in-situ mixing process, a cold recycler granulates the existing pavement and homogeneously mixes in the binding agent and water.

In the in-plant mixing process, RAP and crushed rock are transported to a mixing plant near the construction site.
