As infrastructure development is increasingly linked to reducing greenhouse gas emissions, products such as Wirtgen's new KMA 240i cold blending plant and the WR series cold recyclers could be in demand.
The company is launching the world premiere of the KMA 240i mixing plant, which it claims provides "climate-friendly and cost-effective recycling of building materials". It is also announcing some technology updates for its WR series of cold recyclers.
The KMA 240i mixing plant can be stationed near the construction site where materials such as planer or crushed demolition waste can be delivered. The plant then mixes the material with water-binding agents such as foamed bitumen, bitumen emulsion or cement. The mixed material can then be used for paving.
In addition to cold mixes for bituminous bonded base coats, the plant can also produce mixes for cement-stabilized base coats and rolled concrete at speeds of up to 240 tons per hour, Wirtgen says. “These building materials are integrated into the road construction cycle as high-quality mixes. They can be used for applications ranging from the construction of highways, roads and paths to the construction of parking lots or industrial estates.”
The plant's higher production speed is due to Wirtgen's "double trough technology", which doubles the throughput. “The system enables accurate, reliable and automatic addition of large quantities of hydraulic binders,” the company says. "As a result, the mix production process achieves the highest levels of efficiency and quality."
