In the homogenization process, the powerful milling and mixing rotor of the WIRTGEN soil stabilizer granulates the native soil without the addition of stabilizing agents and loosens it. While a grader profiles the homogeneous soil prepared this way, rollers for soil compaction take care of the compaction process.
A machine train is generally required if the properties of the soil are to be lastingly improved. This begins with a binding agent spreader that deposits the stabilizing agent evenly, followed by a WIRTGEN soil stabilizer. The WR 250 uses its milling and mixing rotor to mix the soil homogeneously with the pre-spread lime. A pressurized scraper on the rear milling drum flap ensures that the treated material is smoothed evenly. While a grader profiles the soil mixture, rollers for soil compaction ensure optimum compaction.
Stabilization with cement creates water-bound base courses. The binding agent is laid by a towed spreader, which is followed by a water tanker. Behind it, the milling and mixing rotor of the WIRTGEN soil stabilizer mixes the soil with the pre-spread cement to form a homogeneous mass. At the same time, water is sprayed into the mixing chamber by means of an injection bar. Here, too, graders profile the treated material and rollers complete the job by nsuring optimum compaction.
Perfect stabilization: the powerful milling and mixing rotor of the WR 250 blends the pre-spread binder into a homogenous soil and stabilizing agent mix.
