Chat Online2014-7-4 · Crushed rock is generally more stable than natural rounded stone. A 36% increase in rock size is recommended for rounded rock. The rock should be durable and resistant to weathering, and should be proportioned so that neither the breadth nor the thickness of a single rock is less than one-third its length.
