Full Process of Asphalt Paving Equipment Support
Asphalt paving is the core link of road construction, which directly affects the durability of the road surface and driving safety. Are you still worried about the low efficiency, insufficient compaction and serious material waste of asphalt paving? Macroad provides a full set of paving equipment combination solutions, including precise spraying of asphalt spreaders, uniform paving of pavers, efficient compaction of rollers, and precise proportioning of stabilized soil mixing stations, reducing construction losses by 25%.
Full Process of Asphalt Paving & Equipment Support
Asphalt paving requires rigorous procedures and professional equipment. From base preparation to final compaction, we break down key technologies and equipment choices for each stage to ensure construction efficiency and pavement quality.
Base Preparation – Stabilized Soil Mixing Plant Builds a Solid Foundation
- Clearing and Leveling
- Stabilized soil mixing plant remove debris and level the ground before construction to avoid uneven bases affecting subsequent paving.
- Stabilized Layer Construction
- Key Equipment: Stabilized Soil Mixing Plant
- Function: Mixes soil, cement, and other materials into high-strength stabilized soil to reinforce the base.
- Advantages: Modular design for rapid deployment, high mixing uniformity, and adaptability to diverse material ratios.
Tack Coat Application – Asphalt Distributor Enhances Layer Bonding
Asphalt distributor spraying asphalt penetration oil evenly on the surface of the base layer to improve the bonding strength between the base layer and the asphalt surface layer and the stability of the base layer
- Key Equipment: Asphalt Distributor
- Function: Intelligent control of spray volume to avoid waste or uneven coverage.
- Advantages: Adjustable nozzle width for narrow roads or wide pavements.
Mix Paving – Asphalt Paver Ensures Uniform Layering
- Temperature and Thickness Control
Asphalt mix should be paved at around 160°C (optimal temperature) to prevent uneven hardening due to rapid cooling.
- Key Equipment: Asphalt Paver
- Function: Automatically adjusts paving thickness to meet industry standards (e.g., <3mm).
- Advantages: Hydraulic extension screed adapts to varying pavement widths, reducing manual adjustments.
Compaction – Road Roller Boosts Pavement Density
- Initial, Secondary, and Final Compaction
- Initial: Steel-wheel road roller quickly compacts the mix to fix its position.
- Secondary: Rubber-tire road roller eliminates voids through kneading.
- Final: Static pressure removes roller marks for a smooth surface.
- Key Equipment: Road Roller
- Function: Compacts asphalt layers via vibration and gravity, extending pavement lifespan.
- Advantages: Multi-mode switching for different compaction phases.
Applications of Asphalt Paving Equipment
Our equipment suits diverse road construction scenarios, from municipal repairs to cross-border infrastructure projects, delivering efficient and stable paving solutions.

- Advantages: Space-saving design for retrofitting old urban areas.
Highways & National Roads
- Needs: Wide-width continuous paving, high flatness, long-term durability.
- Equipment: Large asphalt paver (auto-leveling system), heavy dual-steel-wheel road roller.
- Advantages: High continuous operation capacity (e.g., 5+ km/day).
Airport Runways & Port Pavements
- Needs: Ultra-strong bases, heavy-load resistance, strict flatness.
- Equipment: Stabilized soil mixing plant (precise ratios), rubber-tire road roller (eliminates micro-voids).
- Advantages: Customizable thickened screeds and high-density compaction modules.
Rural & Mountain Roads
- Needs: Steep slopes, sharp curves, long material transport distances.
- Equipment: Asphalt spreader (heated system prevents solidification), compact road roller.
- Advantages: Rugged design for unpaved terrain.
From Technology to Services – Streamline Your Construction
Upgrades in Intelligence and Automation
