I. Technical Scheme and Construction Highlights
1. Material System
- Adopted high-wear-resistant colored modified emulsified asphalt + inorganic composite pigments to ensure weather resistance, UV resistance and non-fading.
- Graded wear-resistant aggregates with a friction coefficient ≥ 65 BPN, meeting the requirements of high skid resistance and high grip for racing levels.
2. Process Advantages
- Normal temperature construction (10–35℃) with quick opening to traffic in 2–3 hours.
- Ultra-thin structure with a thickness of 6–8mm, without affecting the drainage and flatness of the original track.
- Colors: Three-color zoning of track red, warning yellow and functional area blue, with strong visual recognition.
3. Core Performance
- Wear and crack resistance: Withstands high-frequency braking, steering and high-torque impact of racing cars.
- Waterproof sealing layer: Protects the original asphalt structure and extends the service life of the track.
- High and low temperature resistance: Stable at -20℃～60℃, without cracking, softening or peeling.
II. Project Value
- Brand Benchmark: The core pavement supplier for BYD's second global new energy all-terrain race track.
- Scenario Adaptation: Suitable for all working conditions such as professional racing, drifting, wet skid testing and off-road connection.
- Delivery Result: Passed the one-time acceptance and was rated as a High-Quality Project by BYD Engineering Center.
- Industry Significance: The first large-scale application of colored emulsified micro-surfacing in a professional race track, establishing a new benchmark for high-performance colored pavement.
Ill. Case Summary
With its colored emulsified micro-surfacing technology system, Henan Fuxin New Materials provided a high-wear-resistant, high-skid-resistant and high-durable colored pavement solution for Zhengzhou BYD Race Track. With precise color zoning, rapid construction and delivery, and racing-level performance, the project has become a new energy automobile culture landmark and a demonstration of road new material engineering.
