DuraGrav Gravel Roads
Better Gravel Roads with Ultra-Slow Wearing Course Technology
The Gravel Road Challenge
Gravel roads are a very expensive road system. Dust and weathering result in material loss and is an unsustainable practice that requires constant maintenance and material replacement.
Traditional gravel roads suffer from:
- Continuous material loss due to traffic
- Environmental weathering
- Dust generation
- High maintenance costs
DuraGrav Solution
Ecobond Wearing Courses stabilize the top layer to about C3 or C2 standards (UCS/ITS and A19/Sil. Carbide aggregate loss) To provide:
Durable Water Resistant Wearing Course
Long-lasting surface that withstands weather conditions
Ultra-Slow Wearing Course
Dramatically reduces aggregate loss over time
Performance Prediction
Wearing can be predicted based on comparing abrasion and erosion tests to untreated samples. Structural layer durability should be determined as per established cemented base course systems.
Testing Standards
Performance evaluation uses established testing methods including UCS/ITS and A19/Silica Carbide aggregate loss tests to ensure reliable, measurable results.
Additional Applications
This technology can also be used in labour intensive erosion control, for example:
- Road shoulders
- Water ingress prevention
- Edge break reduction
- Aggregate loss prevention
- Pavement structure protection
- Erosion control systems
Labour intensive construction makes relatively thin layers possible to construct (e.g. 30mm-75mm), making it cost-effective for various applications.
