What is 'loose volume' ?

As an example say coverage area is 100m2 and customer needs to install 150mm of compacted base course then a 15m3 solid/compacted to an engineered standard would be needed.

All aggregates are bought loose “truck measure” delivered. Depending upon specific aggregate and use, volume is lost as all the loose particles of aggregate are compacted. For roading aggregates Gap65 & 40 the generally accepted loose-to-solid ratio is 1.4-1.0. Ie 1.4m3 is required as a minimum to achieve a 1m3 solid (installed in place with heavy compaction equipment)measure.

So in case of 100m2 at a spread/compacted in place thickness of 150mm you would need to order 15m3 x 1.4=21m3.

Generally the maximum accepted compaction factor is 1.4 loose to 1M solid if compacting with heavy compaction equipment.

The rule of thumb is to multiply your calculated volume simple by 1.4 to give you ‘loose truck delivered’ volume. Please talk with our Sales Assistance if you require help to determine you final order.
