According to BS-1241, a flakiness index should not exceed 30% irrespective of the aggregate size. Maximum permitted elongated index is 35%, 40% or 45% for aggregate size 21/2" - 2", 11/2" - ¾" and 1/2" - ⅜". Both Flakiness index Elongation Index tests are not applicable to the materials of sizes smaller than 6.3 mm i.e. ¼ ...
