The Role of Grass Paver
Grass Pavers Core Performance：
Grass pavers are a permeable ecological paving material made from recycled plastic (HDPE/PP) or concrete, featuring a honeycomb structure that provides both vegetation growth space and ground load-bearing capacity.
Their core performance includes:
Mechanical Performance
Compressive Strength: Static load capacity of 200–800 kN/m² (depending on thickness and material), suitable for light vehicle traffic.
Impact Resistance: Honeycomb structure disperses pressure, preventing ground collapse.
Ecological Performance
Permeability: ≥90% open-cell rate, promoting rainwater infiltration and reducing surface runoff.
Vegetation Compatibility: Soil filling supports root penetration, with a greening coverage rate of ≥70%.
Durability
UV Resistance: HDPE material with carbon black additive, lifespan ≥20 years.
Temperature Range: -40°C to 80°C (suitable for polar to desert climates).
Grass Pavers Core Advantages：
| Advantage | Comparison with Traditional Paving |
|---|---|
| Eco-Friendly | Replaces hardened surfaces, reduces "heat island effect," and increases carbon sequestration. |
| Cost-Effective | 30–50% lower construction cost compared to permeable concrete, with 60% reduced maintenance expenses. |
| Rapid Construction | Modular assembly shortens construction time by 50% (no complex base layer required). |
| Versatility | Compatible with gravel, turf, or mixed vegetation, adapting to diverse landscaping needs. |
Typical Application Scenarios：
Ecological Parking Lots
Scenario: Commercial and residential parking areas.
Design Focus: Use high-load grass pavers (≥400 kN/m²) filled with gravel and grass seeds to meet vehicle traffic and greening requirements.
Roof Gardens
Scenario: Green building rooftops.
Design Focus: Lightweight PP material (self-weight ≤5 kg/m²) combined with a drainage layer for stormwater management.
Slope Protection Projects
Scenario: Highway slopes, riverbank protection.
Design Focus: Anchored grass pavers (with connecting clips) to prevent soil erosion and promote vegetation recovery.
Fire Access Roads
Scenario: Industrial parks, warehousing, and logistics areas.
Design Focus: Red HDPE grass pavers to mark access roads, with a static load capacity of ≥600 kN/m².
International Application Size Standards
Grass paver dimensions must align with regional load standards and construction practices. Below are mainstream market specifications:
| Region/Standard | Common Dimensions (L×W×H) | Application Scenario | Remarks |
|---|---|---|---|
| Europe (EN 13242) | 600×400×50–100 mm | Municipal roads, private driveways | Modular design, (assembled into curves). |
| USA (ASTM D7068) | 24"×24"×2–4" (610×610×50–100 mm) | Fire access roads, heavy parking lots | Emphasizes freeze-thaw cycle resistance. |
| Asia (JIS A 5371) | 500×500×40–80 mm | Residential areas, park walkways | High proportion of low-cost PP material. |
| International Universal | 400×400×60 mm | Temporary event sites, rooftop greening | Lightweight and portable, reusable. |
Selection Recommendations：
Load Matching
Pedestrian Walkways: 50–100 mm thickness, compressive strength ≥200 kN/m².
Fire Access Roads: 80–100 mm thickness, compressive strength ≥600 kN/m².
Material Selection
HDPE: High load capacity, long lifespan (recommended for parking lots, industrial areas).
PP: Lightweight, low cost (recommended for rooftop gardens, temporary sites).
Drainage Design
High Rainfall Areas: Choose models with ≥95% open-cell rate, with a 10–20 cm gravel base layer.
