Crushing Test On Aggregates

Name of the experiment Aggregate Crushing value test. Objective 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different types of road. Theory The “aggregate crushing value” give a relative measure of the resistance of an aggregate to crushing under gradually applied.Aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3.
