Recyclers and soil stabilisers

Recycling damaged asphalt pavements and stabilising soils

Cold recyclers are used to prepare asphalt pavement on site. In this process, the existing pavement is granulated with the milling and mixing rotor and prepared by adding precise amounts of bituminous binding agents, cement and water. The result is a homogeneous material that can be used to directly repave the soil. Soil stabilisers use the milling and mixing rotor to mix pre-spread binding agents such as lime or cement into the existing, less stable soil and transform it into a high-quality material directly on site.

WS series: Tractor-towed stabilisers

The WS series tractor-towed stabilisers can be quickly and easily coupled to a tractor (minimum engine power output >220 kW). The adjustable rotor plate ensures homogeneous mixing quality. Side plates on skids, mechanical belt drives on each side and an effective milling and mixing rotor all contribute to their high performance. Tractor-towed stabilisers are typically used for soil stabilisation or consolidation in the construction of traffic infrastructure.

WR series: Cold recyclers and stabilisers

The WR series cold recyclers and stabilisers have a variable mixing chamber and microprocessor-controlled injection systems for the addition of bitumen emulsion, water or foamed bitumen. Thanks to an efficient hydraulic flow divider, their all-wheel drive provides maximum traction, while the four-fold full-floating axles ensures best possible ground clearance in difficult terrain. The WR series machines are therefore ideal for a variety of application scenarios ranging from cold recycling - structural road rehabilitation - to the stabilization of various construction materials such as, for example, in soil stabilisation or consolidation in the construction of traffic infrastructure.

WRC series: Wirtgen Rock Crusher

The WRC series machines feature a high-performance crushing and mixing unit with specially developed HT18 crushing tools that enables the crushing and homogenisation of rocks, stones, hand-packed stone pavement layers, concrete rubble or cobblestones. These machines also have a variable mixing chamber and an optional microprocessor-controlled injection system for the addition of water. This enables binding agents and water to be added and mixed in during the crushing and homogenisation process. Thanks to an efficient hydraulic flow divider, their all-wheel drive provides maximum traction, while the four-fold full-floating axles ensures best possible ground clearance in difficult terrain. The WRC series machines are designed and constructed for processing unbound materials and less cohesive soils interspersed with coarse rocks or stones by crushing and homogenisation: cultivation (soil improvement/agriculture), road construction (crushing of concrete fragments and hand packed stone pavement layers), soil treatment/soil stabilisation, maintenance of roadways in opencast mines and quarries etc.

CR series: Cold recyclers

CR series cold recyclers are used for efficient and cost-effective cold recycling of road pavements. Optional microprocessor-controlled injection systems enable precisely controlled addition of water, bitumen emulsion or foamed bitumen. Thanks to the machine concept, these cold recyclers enable selective granulation and homogenisation of the surface layer across the full width of roads or traffic lanes. Using the down-cut method ensures ideal gradation of the material. After granulation and homogeneous mixing with the binding agent, the cold recycler transfers the processed construction material to the material hopper of the downstream asphalt paver with its integrated discharge conveyor. CR series cold recyclers can also be used as high-performance milling machines.

KMA series: Mobile cold mixing plant

The mobile cold mixing plants of the KMA series are easily transportable and can be quickly set up in close proximity to project sites. The heavy-duty twin-shaft pugmill mixer achieves high mixing performance. Microprocessor-controlled injection systems for the addition of a wide range of binding agents ensure that the materials are mixed precisely to the required recipe. The wide slewing angles of the discharge conveyor enable the processed cold mix to be stockpiled or continuously loaded onto transport vehicles.

Laboratory equipment

Cold recycling projects are often varied and challenging. The laboratory equipment assists with the preparation of samples for the analysis and determination of the properties of the construction materials produced in cold recycling. WIRTGEN offers a variety of equipment for this purpose: The WLB 10 S for testing the properties of the foamed bitumen produced by the addition of water, the WLM 30 laboratory-scale mixer with a capacity of 30 kg and the WLV 1 laboratory compactor are used for the production of test specimens from bitumen-stabilised material.
