For determining flakiness index. Particle is flaky when its thickness (smallest dimension) is less than 0.6 of the mid-size of the sieve fraction. Gauge has seven, labeled slots for manual evaluation of particles in the seven openings. The mass of all flaky particles (passing appropriate slots) as percent of the sample is the flakiness index. Flakiness Index and Elongation Index Test on Coarse Aggregates Theory of Flakiness Index and Elongation Index Tests. This test is not applicable to sizes smaller than 6.3mm. The Elongation index of an aggregate is the percentage by weight of particles whose greatest dimension (length) is greater than nine-fifths (1.8times) their mean dimension. This test is not applicable for sizes smaller than 6.3mm. 1223.1 1223.2 APPARATUS A. conforming to the design and

1.1 This test method describes a procedure to determine the Flakiness Index (FI) of aggregates. The FI is used as a design input to determine the rate of application of aggregate and asphalt material for seal coats. 1.2 The flakiness index is a measure of the cubical shape of the aggregate which is 1223.1 1223.2 APPARATUS A. conforming to the design and ... pass through the slot. C. Weigh the particles passing the slot to the nearest 0.1 gram. D.
