Flakiness Index Test for Aggregates

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.
