Flaky is the term applied to aggregate or chipping that are
flat and thin with respect to their width and length.
Aggregate particlie are said to be flakey when there th. is
less then .06 of their mean size.
Aggregates which are flaky and/or elongated will often
lowerthe workability of a concrete mix and may also affect
longterm durability. In bituminous mixtures flaky
aggregatemakes for a harsh mix and may also crack and break
up during compaction and rolling index.
