Whether heavy, coarse-grained or sandy subgrade material: the tractor-towed stabilizer can be relied on to convert it into soil that is highly suitable for placing and compacting. If too coarse, the material to be stabilized is crushed in the mixing chamber by the milling and mixing rotor. Soft soil is covered with lime spread by, for instance, a binder spreader prior to treatment. Subsequent homogeneous mixing by the milling and mixing rotor causes the lime to remove the excess humidity from the soil.
Soil stabilization with added binding agents like cement is a patent remedy for increasing the long-term resistance against stresses resulting from traffic and weather conditions. Soil stabilization produces a ground of permanently high bearing capacity, strength and excellent resistance to frost.
