Mobile cold recycling mixing plant for the production of mixes for road construction by adding various binding agents, such as bitumen emulsion or foamed bitumen. The plant is mounted on a semi-trailer and is driven by an own diesel engine. This mobile design permits easy transport and fast setup on the job location.
The KMA uses graded mixtures of new aggregate, cement and water to produce mixes for hydraulically bound base layers. The mix is transported from the cold mixing plant to the paving site, placed by road pavers and compacted.
Mixing cement into a granulated blend of asphalt and gravel results in a highly stable construction material that meets the requirements of a hydraulically bound base layer.
For the production of cold mixes, granulated material is fed into the cold mixing plant with or without the addition of gravel, is processed with cement and water and is then transported to the nearby site by truck. Paving is mostly carried out by conventional road pavers with subsequent compaction.
Bituminous bound base layers can be produced by mixing bitumen emulsion into a granulated blend of asphalt and gravel material.
For the production of cold mixes, granulated material is fed into the cold mixing plant with or without the addition of gravel, is processed with bitumen emulsion and water and is then transported to the site by truck. Paving is usually carried out by conventional road pavers with subsequent compaction.
Foamed bitumen is produced by adding water to hot bitumen, which increases its original volume many times.
For the production of cold mix, foamed bitumen is injected into the plant's twin-shaft continuous mixer, where it bonds with the mineral aggregate. The resulting cold mix is then used for the production of bituminous bound base layers of high quality.
Bituminous/hydraulically bound base layers of superior quality are produced by mixing foamed bitumen and cement into a graded mix of milled material with or without new aggregate.
For the production of cold mix, foamed bitumen is injected into the plant's twin-shaft continuous mixer, where it bonds with the mineral aggregate, while cement is drawn from a silo via feed augers and is added to the mixing process in precisely metered quantities.
