Soil stabilization scores top marks in comparison to soil exchange as it requires fewer truck transports, results in shorter construction times, saves resources and reduces CO2 emissions. When operating as a soil stabilizer, the WR uses its powerful milling and mixing rotor to mix pre-spread binders, such as lime or cement, into the existing, insufficiently stable soil at working depths of up to 560 mm to convert it into a construction material of high quality in an in-situ process. The resulting homogeneous soil-binder mixture offers high tensile strength, compressive strength and shear strength values as well as long-term water resistance, frost resistance and volume stability.
The WR is equipped with a powerful milling and mixing rotor and state-of-the-art injection systems. The cold recycler mills and granulates the existing asphalt pavement, injects binders and water in precisely metered quantities and mixes all three in a single operation. The new base layers produced in this in-situ process are distinctive for their exceptionally high bearing capacity.
Cold recycling can be achieved either in-plant by hauling material recovered from an existing road to a central depot where it is fed through a mixing unit, or in-place using a recycling machine.
When mixing in-place / in-situ, a cold recycler granulates the existing pavement while mixing in binders and water homogeneously at the same time.
When mixing in-plant, reclaimed asphalt pavement and crushed stone are transported to a mixing plant located in the vicinity of the construction site.
Results of high quality are the main goal of every construction project. This applies to road rehabilitation using cold milling machines and cold recyclers as well as to soil stabilization and the extraction of useful minerals using surface miners. Optimum interaction between the milling drum, toolholder and pick is essential for precise, efficient paving removal.
