Precise control of the cutting depth is a vital requirement that surface miners need to meet for selective mining, the production of level surfaces, and grading. Cutting depth and cross slope are set and controlled via the hydraulic height adjustment feature of the track units.
If the bearing capacity of the asphalt surface layer has been compromised, the road structure must be completely rehabilitated. Cold recycling is the latest trend – a rapid, cost-effective and environmentally friendly process!
Deviations from the target value are picked up by the sensors and calculated by the levelling system, which then automatically transmits a corrective value to the machine. Different sensors are used for different applications depending on the reference used (e.g. pavement surface, kerb or stringline).
The rehabilitation of asphalt or concrete surfaces begins with cold milling machines, which mill or profile the damaged surface. Learn more about the process here.
The levelling control system governs the paving thickness of concrete profiles in accordance with a specified reference. Slipform pavers typically use mechanical systems scanning a stringline to effect horizontalposition and level control.
If the mixing plant is too far away or the construction site doesn’t meet the requirements to conduct the entire recycling process in one pass, cold in-plant recycling is the perfect solution.
Computer-assisted automatic functions not only optimise work processes and thus machine productivity, but also the machine operator’s performance. Our numerous intelligent information and diagnostic systems additionally support the operator and make their job easier – resulting in faster and more efficient operations. A few examples of assistance systems for surface miners are presented below.
Levelling system LEVEL PRO / LEVEL PRO PLUS / LEVEL PRO ACTIVE
In cutting and milling, it is crucial to remove pavements to the specified depth. The intuitive WIRTGEN LEVEL PRO / LEVEL PRO PLUS / LEVEL PRO ACTIVE levelling technology can be relied on to precisely maintain the preset cutting and milling depth. The hightech system is fully integrated into the machine’s overall management system.
Depending on the load they need to withstand, runways are either built using asphalt or concrete. Which building material is suitable for your project?
