Recycled Roadbase is typically a crushed concrete screened and graded to include aggregate ranging from fines through to 20mm. A cheaper substiture for Roadbase and generally adequate for light duty filling and compacting such as under a paved patio. Rated at a minimum of CBR15 (California bearing ratio) but no garuantees are made.
If a compactible product is required for heavy duty areas, such as driveways or retaining wall footings the CBR45 Roadbase is recommended.
1.5 Tonne = 1m3
