Additionally, the new VARIO injection bar for binding agents allows the user to regulate the injection pressure of water and bitumen to achieve more homogeneous distribution in the mixing chamber.
The RES combines an automatic steering system and digital project site documentation in a single app, improving the cost-effectiveness and resource-efficiency of soil stabilisation and recycling operations.
The satellite-based guidance system allows precise completion of project tasks and steers the machine with a precision measured in centimetres, on the basis of a previously calculated reference cut and a predefined overlap of adjacent cuts. At the same time, location-specific parameters are recorded to generate a database for site analysis and documentation.
Parameters such as working width and depth, distance/area worked and fuel consumption are recorded. The system is scalable, which means that other machines such as rollers and compactors involved in the process can also benefit from the data.
To achieve high-quality mixing, the addition of water and binding agents is regulated according to parameters such as the working width and depth, the material density and the machine advance rate. Each injection bar has 16 nozzles, each of which can be activated or deactivated to vary the spraying width.
The novel VARIO injection bar for water, bitumen emulsion and foamed bitumen features an adjustable nozzle cross-section that allows injection pressure regulation and the depth the spray jet penetrates into the milled granulate.
