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.

The particle size distribution of aggregates is a determining factor for the wearing behaviour of asphalts and up to 2.0 mm. Dispensing with hand sieving should lead to a hypothesis that the material momentarily passing through the sieve is proportional to that material momentarily existing on the sieve and capable of passing through it
