Soil improvement - producing soil suitable for compaction
Whether heavy, coarse-grained or sandy subgrade material: the tractor-towed stabiliser can be relied on to convert it into soil that is highly suitable for placing and compacting. If too coarse, the material to be stabilised 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. In earthmoving operations, soil improvement pays off in the construction of, for instance, dams or embankments, backfilling or site haulage roads. Soil improvement has shown itself to be eminently suitable also for landfills with clayey subsoils. Soil processed with suitable binding agents is practically unsusceptible to water and offers optimum conditions for further compaction.
