many different size distributions by one value, and, as shown in Figure 2.2, this is wholly inadequate. In Chapter 3, various mathematical models of the crushing process are dis ussed; the Rosin-Raronler equation is used, quite elegantly, in ore of these models (the Whiten model). 2.2.2 Statistical Functions

AGGREGATE CRUSHING VALUE

AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.
