Use on the construction site
Cold recycling in-situ
Cold recycling with foamed bitumen can be performed either in-situ (on site) or in-plant (in a mixing plant). When cold recycling in-situ, a cold recycler granulates the damaged road pavement while at the same time mixing in foamed bitumen, water and cement in the required quantities. This method produces a new, homogeneous construction material (BSM) in a single operation. The in-situ cold recyclers are equipped with a powerful milling and mixing rotor and an injection system. Some models are additionally fitted with a screed for paving and pre-compaction of the new material mix.
Construction materials in-situ
Generally, all granular construction materials – and RAP materials – are suitable for recycling with foamed bitumen. WIRTGEN recyclers granulate both the asphalt layer and the uderlying layer, mixing the material with foamed bitumen in-situ in a single operation. After compaction, a high-quality bituminous base layer has thus been produced that is capable of withstanding extremely high traffic loads.
