Higher mixing capacities with different input materials
The KMA 240(i) impresses with its ability to process a large variety of non-cohesive base materials, which wheel loaders feed to the plant’s hopper via vibrating grids. This makes it possible to produce cold mixes from a wide variety of new granular mixtures or various milled materials and binding agents. Asphalt milled material, all other non-cohesive materials reclaimed from old road surfaces, and materials from RC processing can all be used to build new road surfaces in an environmentally friendly manner. The ability to completely reuse the material results in high CO₂ and energy savings with minimal construction costs and project periods.
Faster Mix Preparation Thanks to Optimized Metering
Silos or tank trucks supply the cold recycling mixing plant with binding agents, such as hot bitumen, bitumen emulsion, and cement. The precise metering of the input materials and binding agents, the ratio of which is determined in advance by preliminary tests in the road construction laboratory, is monitored by a proven microprocessor control system. The KMA 240(i) ideally loads the new, homogeneous mix directly onto trucks or deposits it continuously on a stockpile. Loading or depositing can be carried out in an extremely flexible manner thanks to the discharge conveyor that can swing 55° to either side.
Cold In-Plant Recycling: Environmentally Friendly, Cost-Effective, Versatile
Cold recycling technology from Wirtgen is an environmentally friendly and at the same time cost-effective rehabilitation method that can be carried out either in place – in which case the damaged pavement is removed by a mobile recycling train, processed on site, and immediately repaved – or in plant.
If the mixing plant is located too far away or the job site doesn’t meet the logistical requirements needed to carry out the entire recycling process in one pass, cold in-plant recycling is often the perfect solution. This method involves setting up the KMA mobile cold recycling mixing plant in the immediate vicinity of the job site. This saves time, truck capacity, and is also extremely environmentally friendly, making it possible to achieve up to 70% fewer CO₂ emissions through cold processing, a 90% reduction in transport volumes, and up to 40% lower construction costs. Furthermore, the high-quality building materials are completely reused.
As a result, Wirtgen’s cold recycling technology not only stands for maximum sustainability, but also offers considerable savings potential in addition to conserving natural resources.
