The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load. The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance, particularly when lower strength is suspected.

Aggregate Crushing Value Test Procedure And Result

Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the ten percent fines value should be determined and used instead.

Aggregate Crushing Value Test Crushing Value Test Of

Mar 30, 2020 The aggregate crushing value test evaluates the ability of the aggregates used in road or pavement construction to withstand the stresses induced by moving vehicles in the form of crushing. With this, the aggregates should also provide sufficient resistance to crushing under the roller during construction work and under rigid tyre rims of ...
