Recyclers and soil stabilizers

Recycling damaged asphalt pavements and stabilising surfaces

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 surface. 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.

The recyclers have a variable mixing chamber and microprocessor-controlled injection systems for the addition of bitumen emulsion, water and foamed bitumen. In the soil stabilization process, the all-wheel drive, all-terrain machines mix binding agents into existing soils, producing load-bearing soils with ideal properties for further roadworks. In the cold recycling process, the existing pavement is milled off and the milled material is then homogeneously mixed with the added binding agents. The new mix of materials then serves as a basis for base courses.

Cold recyclers

Cold recyclers

Cold recyclers in the CR series are used for the cost-effective recycling of pavements. Binding agents and water are added in precisely metered quantities by means of microprocessor-controlled injection systems. Cold recyclers with a paving screed use the down-cut process and immediately repave the recycled construction material. In large projects requiring high daily performances, the recycler transfers the recycled construction material via its integrated discharge conveyor to the material hopper of the downstream paver, which immediately repaves it, achieving a high degree of precompaction. The recyclers in the CR series additionally can be used as high-performance milling machines.

Mobile cold recycling mixing plant

Mobile cold recycling mixing plant

The mobile cold recycling mixing plant is simple to transport and quick to set up in the direct vicinity of the operation site. The robust twin-shaft compulsory mixer achieves high mixing performance levels. Microprocessor-controlled injection systems for the addition of a wide range of binding agents ensure that the materials are mixed precisely to formula. The slewing discharge conveyor with its wide range of motion enables the processed cold mix to be stockpiled or continually loaded onto transport vehicles.

Hot recyclers

Hot recyclers

The remixer and panel heating machine rehabilitate bitumen-bound surface courses up to a depth of 5 cm. The panel heating machine replastifies the asphalt pavement, enabling it to be processed. The downstream remixer scarifies the pavement and processes it in a twin-shaft compulsory mixer. Virgin mix and binding agent can be added to the process. The integrated paving screed then repaves the recycled material true to cross-section, line and level, achieving a high degree of precompaction.
