Sub-bases for paving: a basic guide Society of

The sub-base is the main load-bearing layer of paving construction. A well-designed sub-base should evenly spread the load of traffic, whether pedestrian or vehicular, down to the sub-grade, also known as the formation level. Best practice usually stipulates a geotextile non-woven membrane (e.g. Terram 1000), which acts as a filtration ...

Sub-bases Pavingexpert

2021-5-15  The sub-base layer is often the main load-bearing layer of a pavement. It is designed to evenly spread the load of the paving, and any traffic thereon, to the sub-grade below. A well-constructed sub-base will aid drainage and prevent settlement and channelisation - the phenomenon common on cheap installations of block paving, where two 'ruts' develop in the paving.
