Construction Cases

Double surface treatment Process with Asphalt and Aggregate in Botswana. Asphalt heating temperature is typically controlled between 160-190°C. Constructed using a synchronous chip sealer, the first layer has a spray rate of 1.2 L/m² with aggregate size of 14-20 mm, and the second layer has a spray rate of 0.9 L/m² with aggregate size of 6.5-14 mm. Compaction is performed using double-drum and rubber-tired rollers.

Usage Scenarios

Prime coat: Simultaneous spraying of asphalt and aggregate seals base course pores to prevent water infiltration, enhances bonding with the surface layer, and protects the base course from damage.

Seal coat: Constructed in two layers to improve pavement skid resistance and wear resistance; can serve as a wearing course or maintenance layer.

SAMIL over Cement: Absorbs stress, reduces reflective cracking, and improves interlayer bonding.

Cape Seal: Combines a chip seal base layer with a micro-surfacing or slurry seal surface layer.

Intelligent Control Technology

Chassis: Custom heavy-duty chassis (e.g., HOWO, Shacman) equipped with 300+ HP engines, suitable for extreme conditions like high altitudes and high temperatures.

Synchronous Material Application: High-quality asphalt pump and hydraulically driven aggregate spreader ensure synchronized operation with spray accuracy ≤ ±1.5%.

Intelligent Heating: Italian-made burner with thermal oil circulation enables heating rates up to 20°C/h and maintains constant asphalt temperature.

Fully Automated Control: 10-inch touchscreen displays real-time spray pressure, temperature, vehicle speed, etc. Supports one-touch parameter presets and adaptive speed adjustment.

Capacity and Efficiency

Large Capacity: Asphalt tank volume: 8–10 m³; Aggregate hopper volume: 10–14 m³. Single operation coverage exceeds 15,000 m².

High Efficiency: Maximum working speed: 8 km/h; Daily construction capacity: 30,000–50,000 m² (50% more efficient than traditional methods). Dual-path cleaning system (high-pressure air + diesel) cleans pipelines within 10 minutes, minimizing downtime.

Durability Assurance: The key components are equipped with a variable pump hydraulic system, and the average downtime-free time exceeds 2000 hours. Multi-layer anti-corrosion tank treatment ensures a service life of 5+ years.

Safety & Environmental Protection

Safety: Daily pre-operation checks of brakes and spray systems are mandatory. High-temperature asphalt tank surfaces (exceeding 60°C) must display clear warning signs, and operators require full heat-resistant suits. Erect barriers and warning signs during operations to prevent unauthorized access, injuries from splashing hot asphalt, and aggregate spillage.

Environmental Protection: Clean energy for asphalt heating reduces emissions; collect leaked asphalt to prevent soil contamination; recycle excess aggregate; clean the site post-construction to avoid dust and waste pollution.

Service & Support Commitments

Spare Parts Guarantee: 10-year continuous supply commitment with 95% inventory coverage; emergency orders shipped globally within 48 hours.

Rapid Response: 4-hour technical team activation guaranteed.

International Support: Multilingual specialists (English/Russian/Spanish, etc.) deliver tailored solutions for overseas issues within 72 hours.

Global Service: Products exported to 60+ countries, serving 8M+ m² of road projects with 85% customer repurchase rate, adaptable to diverse international construction standards.
