The flakiness and elongation of aggregates can affect the workability of a concrete mix and its long term durability. In bitumenous mixture, aggregate flakiness affects the quality of compaction by rolling
STANDARD: BS 812
Aggregate particles are considered elongated when there is more than 1.8 of their nominal size.
Used to determine if aggregate particles are to be considered flaky, i.e. their thickness is less than 0.6 of their nominal size.
