Flakiness & Elongation of Aggregate

This aggregate classification system uses a HM-925 Thickness Gauge for determining flakiness index and a metal HM-926 Length Gauge for determining elongation index. Aggregate is separated into seven sieve fractions from 63—6.3mm, and each fraction is evaluated separately.

Test aggregates must be sieved using sieves with openings of 63, 50, 37.5, 28, 20, 14, 10, and 6.3mm. These are available as 200mm diameter brass frame sieves with stainless steel cloth as International Test Sieves.
