A thermal mixing process turns aggregates and bitumen into asphalt for road construction. We explain the process and different types of equipment used.
Even More Possibilities | 2000-2009 | Company history | Wirtgen GmbH
WIRTGEN focuses on expanding its leading position in milling, cold recycling, and mining, as well as capturing a greater share of the concrete paving market.
For many years, HAMM has been developing fuel-efficient machines and machine control systems for an efficient and resource-responsible workflow on the construction site.
The potential for saving energy is one of the most important drivers of this trend: warm mix asphalt (WMA) as a road construction material is currently becoming more and more important. Technologies and solutions from the Wirtgen Group are the perfect response to this trend – and play an important role in ensuring that the production and utilisation of lower-temperature mixes is achieveable with conventional methods and equipment.
Green technology from a green factory: the BENNINGHOVEN factory and the contributions it makes to energy-efficient and environmentally friendly production.
Cold recycling with foamed bitumen has become an established technology worldwide and is now increasingly moving into the focus of road authorities and construction companies for use in the rehabilitation and new construction of road pavements. Cold recycling with foamed bitumen produces flexible and highly durable base layers. Being a part of the pavement structure, these are the perfect foundation for the final asphalt overlay to be built at reduced layer thickness. Foamed bitumen is produced from approx. 175 °C hot road-grade bitumen using state-of-theart technology. Microprocessor-controlled injection systems installed in the WIRTGEN recyclers produce the foamed bitumen and inject it into the mineral aggregate in precisely metered quantities.
SPECTIVE CONNECT is the logical extension of SPECTIVE because it moves the user interface of the crusher into the excavator or wheel loader and thus directly to the operator.
We offer mature processes for facilitating the construction of heavy-duty motorways or airport runways an the production of poured-in-place concrete profiles. Make use of our broad offer of machines for high precision in concrete paving.
