Aggregate 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.

Producing meaningful concrete and aggregate test results rely heavily on following strict procedures in test methods and practices published by ASTM, AASHTO, and other organizations. Requirements for tests on aggregates, concrete compressive strength tests, and other methods are written in clear, concise language following form, content, and style guidelines, but often lack basic explanatory ...
Aggregate used in road construction, should be strong enough to resist crushing under traffic wheel loads. If the aggregates are weak the stability of the pavement structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test.
Procedure of the LA Abrasion Test: Prepared sample is placed in the abrasiontesting machine. A specified number of steel spheres are then placed in the machine and the drum is rotated for 500 revolutions at a speed of 30 33 revolutions per minute (RPM).
