Wirtgen’s soil stabilisation technology scores top marks

Soil stabilisers convert ground of insufficient bearing capacity into soil that is highly suitable for placing and compacting. Added lime improves the existing soil, while added cement strengthens it. The Wirtgen Group soil stabilisers master a wide range of different applications in soil improvement and soil strengthening, such as the construction of roads, parking lots, industrial facilities, airports, harbour facilities or track beds. They can also be used for various earthmoving operations, such as the construction of embankments, slopes and backfills.

The technology makes use of existing materials, requiring only small quantities of additives or binding agents to be added. The reclaimed, bound and unbound road construction materials are fully reused. In addition, the fast-paced method minimises space requirements and environmentally harmful disruptions to traffic.
Soil stabilisation 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 stabiliser, 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 key benefits of environmentally friendly soil stabilisers:
• Shortens construction times
• Is a resource-efficient process
• Dispenses with the need to create stockpiles
• Minimises environmentally harmful disruptions to traffic
• Reduces the number of truck transports to the construction site
• Reduces binder requirements
• Significantly reduces emission and in particular CO2 levels.
