    Theory Aggregate Crushing Value Test Of Aggregate

    Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil cement, and in new concrete. After harvesting, aggregate is processed crushed, screened, and washed to obtain proper cleanliness and gradation.Crushing strength of road stone may be determine either on aggregates or on cylindrical specimen cut out of rocks. The two tests are quite different not only in the approach but also in the expression of the results. Aggregate used in road construction, should be strong enough to resist crushing.
