flakiness index = [ w / W ] X 100<br />
F. I. = [ w / W ]<br />
X 100<br />
The Flakiness Index of a given aggregate sample is found to be _______ %.<br />
Elongated aggregate are less workable , they are also likely to<br />
break under smaller load s than the aggregate which are spherical or cubical<br />
, flakiness index values in excess of 15 % are generally consider<br />
undesirable . If is desirable that flakiness index of aggregate used in road<br />
construction is less than 15 % and normally does not exceed 25 %.<br />
If the flakiness index is more than the aggregate can take less<br />
loads and are liable to fail under less load . So it is not desirable to use<br />
aggregate of higher flakiness index is permanent .
