Can river rock be used as a subbase in place of crushed stone?

Can river rock be used in place of crushed stone as a sub base for foundations, roads, etc. or does the smoothness cause problems when it comes to movement, compaction, settling, etc.?

Sub-bases | Pavingexpert

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.
