## Detailed introduction

DETERMINATION OF AGGREGATE CRUSHING VALUEaggregate 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. APPARATUS The apparatus of the aggregate crushing value test .crushing value test of aggregate pdfabrasion test, crushing value test for bituminous concrete mix pavements. A study has been conducted on unmodified aggregates using these plastic coated.crushing test of aggregatesAggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
