That said, different types of gravel drain better than others. One of the advantages of going with a gravel or stone driveway versus a solid concrete or macadam (tar and chip) surface is that gravel offers better drainage. As such, crushed stone requires less maintenance and refreshing than natural stone. This allows the individual pieces of stone to interlock with each other, preventing them from moving as traffic rolls over the driveway. As such, natural gravel driveways often need edging to keep the gravel in the driveway.Ĭrushed stone typically has irregular sizes, a rough texture, and angular edges that are created during the crushing process. Because of this, it’s more likely to migrate out of the driveway when a car rolls over it. Natural gravel, such as pea gravel, has a rounded shape and smooth texture. Natural gravel comes in a variety of different types, ranging from river rock to pea gravel.
