Can the sand bedding be omitted in paving block pavement?

Can the sand bedding be omitted in paving block pavement?

In the paving block pavement, it normally consists of the following main elements: sub-base, sand bedding and paving blocks. Sub-base is the main structural element to take up traffic load and spread it into larger area so that the traffic stress is small enough for subgrade to sustain. Sand bedding is used for providing correct line and level for paving blocks to lie on. To achieve this, screeding of bedding layer is implemented so that the paving blocks could be laid directly on it without the need of further leveling.

The large range of particle sizes associated with sub-base renders it unsuitable to provide a uniform surface with correct level for paving blocks to lie on.
