Road Bases & Crushed Rock

Search MaterialSales by your town and select Road Bases & Crushed Rock. Listings cover DGB20, DGB40, recycled road base (cheaper sustainable alternative), stabilised road base, engineered fill and asphalt. Suppliers within ~150km of the searched town are surfaced and sorted nearest-first.

DGB20 road base typically costs $40-70 per tonne ex-GST depending on location and supplier. Recycled road base is usually 20-35% cheaper — often $30-50 per tonne. Specialty grades like cement-stabilised road base and engineered fill cost more. MaterialSales lists each supplier's live ex-GST price so you can compare without phoning around.

A typical residential driveway uses 100-150mm of compacted road base. For a 5m × 15m driveway (75m²) at 100mm compacted depth, you'd need roughly 11-13 tonnes of road base (allowing for compaction). The supplier will confirm exact quantity when you provide dimensions.

DGB20 (Dense Graded Base, 20mm) is finer with smaller maximum particle size — used for finer finish work, paths, paver sub-base and topping layers. DGB40 (40mm) is coarser, used for thicker pavement layers and heavier-duty applications like driveways, car parks and hardstands. Both compact to a hard CBR > 80 surface.

For domestic driveways, car parks, paths and most light-commercial uses, recycled road base (made from crushed concrete and reclaimed asphalt) performs comparably to virgin DGB and is typically 20-35% cheaper. For heavy industrial and structural applications, the engineer may specify virgin DGB or stabilised base — check the spec.
