The powerful recycler for demanding operations

  • The powerful recycler of the WR series is particularly suitable for demanding operations.
  • With a working width of 7 ft. 10 in. (2.40 m) and a maximum working depth of 22 in. (560 mm), the WR 250i is a machine of high performance when it comes to particularly challenging projects.
  • Thanks to its high performance levels in milling and mixing, the recycler will tackle the most challenging of operations in soil stabilising and cold recycling.
  • When it comes to soil stabilising, the ideal performance range is between 60,000 and 130,000 ft² a day (6,000 and 12,000 m²/day).
  • For cold recycling, the ideal performance range is between 700 and 1,200 square metres per hour and 20 to 25 cm of asphalt thickness.

Soil stabilization with WR model series

Soil stabilization outperforms soil replacement thanks to fewer truck trips, shorter construction times, conserved resources, and lower CO2 emissions. The WR soil stabilizer uses its powerful milling and mixing rotor to mix pre-spread binding agents such as lime or cement into existing soil with insufficient bearing capacity, transforming it into a high-grade building material right on the spot. The resulting homogeneous mixture of soil and binding agent offers excellent tensile, compressive, and shear strength, long-term resistance to water and frost, and volume stability.

Cold recycling with WR model series

The WR is equipped with a powerful milling and mixing rotor as well as state-of-the-art injection systems. The cold recycler uses the milling and mixing rotor to mill asphalt pavements, granulates them, sprays binder and water in precisely measured doses, and mixes it all together in a single operation. The new base layers produced on site then stand out thanks to their exceptional bearing capacity.

Mixing procedures

Cold recycling can either be carried out in-plant by transporting the material recovered from an existing road to a central warehouse and passing it through a mixing plant, or in-place/in-situ using a cold recycler.

In the in-place/in-situ mixing process, a cold recycler granulates the existing pavement and homogeneously mixes in the binding agent and water.

In the in-plant mixing process, RAP and crushed rock are transported to a mixing plant near the construction site.

WIRTGEN cutting technology

High quality results are the 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 minerals with surface miners. In order to remove pavement with precision and efficiency, it is essential that the drum, pick holder, and pick work together perfectly.

WIRTGEN is the market leader in cutting technology and offers customers high-performance cutting systems whose components are designed to be fully compatible. In addition, WIRTGEN continuously makes advancements to these cutting technology components, incorporating its practical experience and feedback from customers into the process.
