Class II Rip-Rap is large stones with approximate size range between 8 to 24 inches in diameter, used for heavy erosion control on shorelines, slopes, and embankments, with individual rocks weighing between 10 to 200 pounds, providing a durable, angular surface for water flow management.
Typical Size & Weight
- Diameter: 12 to 18 inches (approx. 300-450mm).
- Weight: Around 10 to 200 lbs per stone, depending on density and exact dimensions.
- Gradation: Often specified with percentages, e.g., up to 10% less than 12 inches, but generally within the 12-18 inch range.
Common Uses
- Stabilizing stream banks and shorelines.
- Protecting bridge abutments and culvert outlets.
- Lining large ditches and V-ditches.
- Landscaping and building retaining walls.
Key Considerations
- Angularity: The stones should be hard, angular, and durable to resist weathering and water.
- Project Needs: Specific site conditions, water velocity, and slope angle determine the exact riprap class and size required.
- Standards: Always check local or project-specific standards (like ASTM or state DOTs) for precise gradation requirements.
