0/4 Ga85 (Dust)

Product Description

A sharp, angular fine aggregate produced from crushed stone. The well-graded fines bind under compaction to create a dense, level surface—ideal as a blinding/binding layer over Type 1 or to regulate shallow depths before concrete, paving, or asphalt. Where specified, supplied as 0/4 Ga85 to EN 13043 for use as asphalt sand. Not free-draining and not a replacement for building/masonry sand. Typical uses Blinding over sub-base prior to concrete/asphalt Regulating shallow hollows, patching, and haunching Bedding under flags/kerbs where a tight, bound layer is required Sand component in bituminous mixes (EN 13043 0/4 Ga85) Key properties Size: 0–4 mm (crushed, angular) Standard (on request): EN 13043 0/4 Ga85 Behaviour: Compacts tightly; non-free-draining Typical compacted bulk density: ≈1.9 t/m³ (varies by rock & moisture) Coverage guide (approx.) 25 mm depth → ~21 m²/tonne 50 mm depth → ~10.5 m²/tonne 75 mm depth → ~7 m²/tonne Actual yield varies with rock, moisture, and compaction. Quantity formula Tonnes ≈ (Length × Width × Depth in metres) × 1.9 Installation notes Moisture-condition for best binding; compact with roller/plate Do not lay in standing water; allow for falls/drainage layers as required Use building/washed sand where a mortar or free-draining sand is specified
