Type 3 Aggregate Calculator
Un-compacted Cloburn aggregates weigh 1.4 tonnes per cubic metre. Therefore if you wish to apply them at a 50mm depth (the normal depth for a driveway) one tonne will cover 14 square metres. For pedestrian pathways, 35mm is normally sufficient in which case 1 tonne will be sufficient to cover approximately 20 square metres.
