Abstract
One established method of estimating the force required for the ten per cent fines test on an aggregate is to divide the number 4000 by the aggregate impact value. However recent analysis of ten per cent fines and aggregate impact data for 79 aggregate samples of various rock types suggests that this method commonly produces too high a fines yield. From the present work it appears that use of the value 2800 in the place of 4000 would increase the probability of a valid estimate of the test load.
