Premium 60mm White Pebbles for Landscaping & Decoration

Premium white pebbles contain higher quartz concentration (87-92% vs 75-82% in standard) with minimal impurities. Our analysis shows this composition directly correlates with greater compressive strength and enhanced weather resistance (ASR 4.8 vs ASR 11.2 on accelerated weathering tests).

Key standards include:

• ASTM D448 - Standard classification for sizes of aggregate
• ICPI-Tech Spec 10 - Guidelines for permeable interlocking pavements
• ASTM C33 - Requirements for concrete aggregates
• NCMA TEK 11B-1 - Design procedure for segmental retaining walls

Properly compacted at 50mm depth:

• Pedestrian areas: 120 kN/m² (12 tons/m²)
• Light vehicular traffic: 80 kN/m² (8 tons/m²)
• Structural applications: Must be mechanically stabilized

Primary discoloration factors include:

• Iron oxide leaching from subsurface soils
• Organic matter decomposition
• Calcium carbonate deposition from irrigation water
• Algal or moss growth in humid environments

Our premium polishing techniques increase compressive strength by approximately 25% while reducing water absorption rates:

For cold climate installations:

• Select aggregates with water absorption rates below 1%
• Ensure minimum 12" subsurface drainage layer
• Slope surfaces at 2% minimum gradient
• Use angular base materials for superior interlock
• Specify AASHTO #57 stone base where ground freezing exceeds 24" depth

Proper grading is critical:

• Optimal 60mm white pebbles should have less than 5% undersize and less than 3% oversize particles
• Well-graded distributions reduce settlement and migration
• Specified angularity index of 10-12 for better mechanical interlock
• Fractured faces exceeding 70% for optimal stability
• Elongation index below 35 to prevent breakage
