Asphalt Paver in the Macroad

Asphalt paver is the core equipment in road construction, which spreads the pre-cast asphalt mixture evenly on the ground to form a strong, smooth, and durable pavement, so their performance has a direct impact on the smoothness and durability of the pavement. macroad provides two categories of wheeled and tracked asphalt paving machines to meet the needs of all scenarios, from city streets to airport runways, and helps the global road construction industry with intelligent control and high reliability.

Core Application Scenarios – Covering Diversified Needs

Application Fields of Asphalt Pavers

Main roads and highways: Continuous paving width up to 12 meters, automatic leveling system ensures ±2mm leveling error to meet the requirements of heavy traffic.
Municipal Maintenance and Repair: Compact wheeled pavers with flexible turnaround for fast localized repairs (e.g. pothole filling, joint treatment).
Airport Roads: High-density compaction technology + high-temperature-resistant screed, to cope with the impact of aircraft landing and taking off and extreme temperature difference environment.
Industrial parks and parking lots Low-speed, high-precision mode ensures even paving in complex areas (e.g. curves, ramps).

How does an Asphalt Paver Work

Core structure and functional modules of asphalt paver

The asphalt paver consists of two major asphalt paver spare parts: the host system and the ironing device. Its working principle is based on the coordinated operation of mechanical transmission, hydraulic control and intelligent sensing technology

machine model

Host system

  • Power system: The diesel engine or electric motor provides the power for the whole machine, and drives the hydraulic pump group through the transfer case to provide energy for subsystems such as walking, feeding, and vibration.
  • Travel system: It adopts crawler type (adaptable to heavy loads) or tire type (strong maneuverability) design, driven by a closed hydraulic circuit, and equipped with a microprocessor to control the walking speed and synchronization to ensure uniform paving.

Material feeding and distributing system

  • Scraper conveyor: The asphalt mixture poured into the hopper by the dump truck is transported to the rear paving room, and the feeding amount is automatically adjusted by the contact sensor.
  • Spiral distributor: Independently hydraulically driven on the left and right, the material is evenly distributed along the full width, and the material level height usually submerges the spiral blade to maintain the density.

Screeding device

  • Scraper conveyor: The asphalt mixture poured into the hopper by the dump truck is transported to the rear paving room, and the feeding amount is automatically adjusted by the contact sensor.
  • Spiral distributor: Independently hydraulically driven on the left and right, the material is evenly distributed along the full width, and the material level height usually submerges the spiral blade to maintain the density.

Key work process of asphalt paver

work process

Mixture Conveying and Distribution

  • Longitudinal Material Transfer: The scraper conveyor transports asphalt mixture from the hopper (loaded by dump trucks) to the front of the paving chamber, ensuring continuous supply via chain/belt mechanisms.
  • Horizontal Uniform Spreading: A dual-spiral distributor (symmetric left/right) spreads the mixture laterally at a controlled speed, forming an even, continuous material pile across the paving width to prevent segregation.
  • Speed Synchronization Control: A frequency converter adjusts the speed ratio between the scraper and spiral (1:1.2–1:1.5) to balance material flow, avoiding overload or shortage for consistent base-layer preparation.

Vibration Compaction & Loose Paving Control

  • Dual Tamping Beam Action: Front and rear tamping beams operate at low (20–40 cycles/min) and high (50–80 cycles/min) frequencies, respectively, to sequentially reduce voids and enhance particle interlock in the mixture.
  • Vibrating Screed Integration: The screed’s built-in high-frequency vibrators (30–50 Hz) combined with its self-weight densify the paving layer, re-arranging particles to achieve an initial compaction degree of 85%–90%.
  • Loose Paving Coefficient Management: Precision control of the coefficient (1.15–1.35, adjusted by aggregate size) balances material looseness and compaction efficiency, minimizing reliance on post-paving rollers.

Automatic Leveling & Thickness Control

  • Multi-Sensor Monitoring: Longitudinal slope sensors (±1 mm accuracy) track elevation via reference lines or existing layers, while transverse sensors (±0.1% error) ensure road cross-slope matches design for drainage and load distribution.
  • Hydraulic Dynamic Adjustment: A closed-loop system uses deviation signals to activate leveling cylinders, adjusting the screed’s traction point height in real time to maintain paving thickness within ±2 mm error.
  • Intelligent Reference-Free Technology: Laser scanning (RSS) or sonar balance beams (SAS) replace traditional reference lines, adapting to complex scenarios (curves, variable slopes) to achieve final flatness ≤2 mm/3m for high-quality pavements.

Selection Guide – Four Steps to Lock in the Best Asphalt Paver

Clear Core Construction Parameters

  • Paving Width: Choose the best asphalt paver according to the road design width, such as APZ60E covering 6 meters, or an extended model, such as APE90, which can be expanded to 15 meters.
  • Base Layer Type: Stabilizing the soil base requires a higher excitation force, and it is recommended to match the infrared heating function model for the old asphalt paving.
  • Daily Average Project Volume: Wheeled models such as APL45E can be selected for projects below 500 tons, and crawler models such as APE75 are preferred for large projects.

Evaluate Terrain and Transfer Conditions

  • Hard Ground/Short Distance: Wheeled models, turning radius ≤5 meters, suitable for frequent municipal transfers.
  • Soft Foundation/Ramp/Long Distance: Crawler ground pressure ≤0.08MPa, slope adaptability up to 15°, avoiding the risk of getting stuck.

Balance Cost and Long-term Benefits of Asphalt Paver

  • Budget Sensitive: The initial road paving machine price of wheeled models is 20% lower than that of crawler models, suitable for short-term projects.
  • Long-term projects: crawler fuel efficiency is 18% higher, and the comprehensive cost of projects over 3 years is better.

Matching special process requirements

  • Temperature control accuracy: double-layer insulation hopper is optional in cold areas, and the temperature difference of the mixture is ≤±5℃.
  • Automation upgrade: 3D paving control system is suitable for complex overpass curved surface construction.
