The key components of soil stabilization

Milling and mixing rotor

The soil stabilizer’s robust milling and mixing rotor is fitted with point-attack cutting tools for soil stabilization which rotate in special quick-change toolholders. Toolholders and cutting tools are arranged on the rotor in an elevated position, ensuring that the construction material is thoroughly mixed with the binding agents.

The engine power is transmitted to the milling and mixing rotor via a direct mechanical belt drive, ensuring maximum efficiency. The design of the stabilizer’s drive system with belt pulleys and power belt enables four different rotor speeds to be selected, depending on the intended application.

Variable milling and mixing chamber

The quantities of material to be mixed depend on the stabilizer’s working depth. Wirtgen’s high-performance soil stabilizers feature a variable mixing chamber, which enables them to always adapt to the job at hand. The larger the working depth, the deeper the rotor is lowered into the soil, resulting in an increased mixing chamber volume.

Decompaction increases the volume of the existing soil, with the decompaction factor strongly depending on the condition of the in-situ material.

All-wheel drive

Soil stabilizers are often required to work their way through wet and muddy soils. All self-propelled Wirtgen soil stabilizers are therefore equipped with all-wheel drive, which offers excellent traction in any working situation. Separate hydraulic circuits for each wheel, as well as four large wheels in “heavy-duty” design with reinforced cleats ensure permanent traction.
