Compaction System for Road Recycling Machines

Product Specifications

Technical details and manufacturing context for Compaction System

Definition

The compaction system is a critical component of a road recycling machine that applies controlled pressure to the milled and mixed asphalt material. It ensures proper density, eliminates air voids, and creates a uniform, durable pavement layer by compacting the recycled material to meet engineering specifications for load-bearing capacity and longevity. The system typically uses hydraulic or mechanical force applied through vibrating plates, rollers, or tampers to compress the asphalt mixture. It operates by generating downward pressure and vibration frequencies that rearrange aggregate particles, reduce air pockets, and increase material density to achieve optimal compaction levels for road construction standards. Key parameters include compaction force (50–200 kN), vibration frequency (30–60 Hz), amplitude (0.5–2.0 mm), working width (2000–2500 mm), system weight (1500–3000 kg), hydraulic flow rate (60–120 L/min), operating temperature (-20 to 80°C), ingress protection (IP54–IP65 per IEC 60529), and material grade (Q345B per GB/T 1591). These values are reference ranges and must be verified for the specific model and application. The system is constructed from high-strength steel, hardened alloy components, and hydraulic seals and hoses. It is designed for integration into road recycling machines, with interfaces for hydraulic power, control signals, and mechanical mounting. When selecting or verifying a compaction system, confirm the required compaction force, vibration frequency, amplitude, and working width against the machine's specifications and the road construction standards. Also verify the operating pressure, hydraulic flow rate, and temperature range to ensure compatibility with the existing hydraulic system. Check the ingress protection rating for dust and water resistance, and confirm the material grade for the frame. Maintenance signals include reduced compaction efficiency, unusual vibration or noise, hydraulic leaks, and seal degradation. Failure boundaries include operating outside the specified temperature range, exceeding the maximum compaction force, or using incompatible hydraulic fluids. Always consult the legal manufacturer or supplier for model-specific values and standards.

Working Principle

The compaction system uses hydraulic or mechanical force to drive vibrating plates, rollers, or tampers that press down on the recycled asphalt mixture. The downward pressure and vibration frequencies rearrange aggregate particles, reduce air voids, and increase material density. This achieves the required compaction level for a stable road surface. The system operates within specified parameters for pressure, force, frequency, and amplitude, which must be adjusted based on material type and layer thickness.

Frequently Asked Questions

What compaction force can this system deliver?

The reference compaction force range is 50–200 kN. Higher force is used for thicker layers. Confirm the required force based on your road construction specifications and the machine's capabilities.

What is the vibration frequency range?

The reference vibration frequency range is 30–60 Hz, adjustable for material type. The amplitude range is 0.5–2.0 mm, with high amplitude for thick lifts. Verify these settings for your specific application.

What are the operating temperature limits?

The reference operating temperature range is -20 to 80°C. Seals degrade above 80°C. Ensure the system operates within this range and check the ingress protection rating (IP54–IP65) for dust and water resistance.
