Road Flattener Machine

Road Flattener Machine

Specifically designed for contemporary road construction and pavement renewal assignments, the road flattener machine is a professional-grade compaction and leveling device. Combining accurate grading capabilities with compaction technology, this adaptable machine provides a smooth, long-lasting road surface. The innovative design caters to the increasing need for efficient quality road finishing in the urban and rural landscape. We harness technological advancements and innovate the art of engineering our road flattener machine, so it performs reliably. And when it comes to asphalt paving finishing, pothole repair, and surface leveling operations, this equipment is especially useful, allowing contractors to achieve perfect road flatness and compaction density.

Advantages of Road Flattener Machine

Precision Leveling Technology

The Road Flattener uses a unique dual-action leveling system combining vibratory compaction with real time surface profiling. This technology uses laser-guided leveling control that automatically optimizes the work to always comply with the ±3mm flatness tolerance, helping to cut human corrections as well as material waste.

High-Efficiency Compaction

The machine is running at variable-frequency vibration (25-40Hz) and adjustable amplitude (0.5-2.0mm), which can achieve the best compaction effect of different pavement layers. Its smart system monitors material resistance and dynamically adjusts vibration parameters to achieve 95-98% density without over-compacting the mass.

Multi-Surface Adaptability

The system for quickly changing attachments enables the machine to switch from asphalt, to concrete, and even to granular base material in just a few minutes. Dedicated finishing plates and compaction rollers ensure that the results are equally flawless across all common road construction materials.

Road Flattener Machine

The next generation of road finishing technology — the Road Flattener Machine — built for continuous operation with a rugged steel frame. Equipped with a 74kW of global emission standards compliant diesel engine, the 2.5m wide working unit offers leveling and compaction capability. The hydrostatic transmission stator load delivers smooth, responsive control with working speeds from 0-15m/min.


It offers 360° of visibility, a large air suspension chair, and a touchscreen control panel paired with highly ergonomic design. Real-time surface profile data, compaction results, and machine performance metrics are displayed on an integrated Grade Control Pro system. Thermal cameras (optional) monitor material temperatures during asphalt operations.


The, machine has been built for durability, which is evident as wear-resistant components are used throughout the compaction and leveling systems. A state-of-the-art automatic lubrication system services vital parts, whereas the centralized service platform streamlines regular upkeep. The chassis and the operator are protected from excessive vibration by special vibration isolation mountings.


The machine is telematics ready with cloud-based data logging for smart construction management. This enables project managers to track progress, confirming compaction results and generating quality reports from remote locations. It interfaces with most common construction management software platforms.

What surface flatness tolerance can be achieved?

The machine maintains ±3mm flatness over 3m spans when properly operated, meeting most stringent road specifications.
The smart system automatically adjusts temperature-compaction curves for various mix designs, including SMA and porous asphalt.
Under typical conditions, it can finish 8,000-12,000 m² per day depending on material and required compaction passes.
