Flakiness Index = [W 2 / W 1] x 100. Where, W 2 = Weight passed from 0.6 x d mean size. W 1 = Total weight of aggregates. Flakiness Index of aggregates used in road construction should be less than 15% and normally does not exceed 25%. It is not desirable to use flaky particles in construction of roads especially in surface course.

Flakiness Index = Weight of aggregate passed through width gauge 10 mm to 6.3 mm (W2) / Total weight of aggregate sample taken (W1) = (W2/W1) x 100. For example, Weight of aggregate passed through width gauge of 10 mm to 6.3mm (W2) = 200 gm and Total weight of aggregate sample = 1000 gm.
