Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Colored Asphalt Iron Oxide
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Transforming the Urban Landscape
At Deqing Demi Pigment Technology Co., Ltd., we believe that roads can be more than just grey. Our colored asphalt series is at the heart of modern "Cool City" initiatives. By providing vibrant reds, yellows, and greens, we help city planners improve traffic safety and reduce the "Urban Heat Island" effect. Our pigments are tested for global use, ensuring that from the heat of the Middle East to the cold of Northern Europe, our colors remain bright and the roads remain strong.
Colored Asphalt Usage Areas
- Urban Bus Lanes: Long-lasting red lanes for public transport identification.
- Parks & Leisure: Decorative paths for gardens, zoos, and resorts.
- Cool Pavements: Light-colored asphalt to reduce surface temperature in cities.
- High-Speed Interchanges: Color-coded ramps for improved driver navigation.
Asphalt Tech Technical Specs
| Metric | Value | Standard |
| Heat Stability (10 min) | 180∘C−220∘C | Internal Method |
| Residue on 325 Mesh | Max 0.2% | ISO 787-7 |
| Oil Absorption | 18 - 25 g/100g | ISO 787-5 |
| Lightfastness | 8 (Blue Wool) | ISO 105-B02 |
| Density | 4.6 - 5.2 g/cm³ | ISO 787-10 |
Performance Attributes
- High Thermal Barrier: Maintains color chroma even at peak mixing temperatures.
- Enhanced Visibility: Significant improvement in low-light and rainy conditions.
- Slip Resistance: Does not negatively impact the "Skid Resistance" of the road surface.
- Durability: Resistant to gasoline, oil spills, and common road chemicals.
Q: Does colored asphalt require a special binder?
A: While it works with black bitumen (mostly for Reds), a "Clear Binder" is recommended for bright Yellows and Greens.
Q: How much pigment is needed?
A: Typically 3% to 5% by weight of the total mix, depending on the target intensity and binder color.
Municipal Technical Support
We provide "SRI (Solar Reflectance Index) Reports" to help your colored asphalt projects qualify for environmental and energy-saving building credits.
Pelletized Options: We offer our asphalt pigments in a pelletized/granulated form for use in automated silo dosing systems, ensuring zero dust and high precision.
The Science of Heat Mitigation
In colored asphalt, we focus on "Albedo Enhancement." Traditional black asphalt absorbs up to 95% of solar energy. By using our high-chroma pigments, especially in the red and yellow spectrum, we increase the surface reflectance. This leads to a measurable drop in "Surface Temperature" of up to 10∘C to 15∘C. We use "NIR (Near-Infrared) Spectroscopy" to ensure our pigments reflect the invisible heat-carrying wavelengths of sunlight, making our roads part of the solution for global warming.
