May 17, 2019 Concept and significance of the Aggregate crushing value test. The aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load
The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.

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.
Dec 19, 2019 In order to evaluate the resistance to impact of aggregate, the aggregate impact test is conducted. Aggregate impact value gives the idea about how much impact load can be resisted by aggregate. Actually, aggregate should be sufficiently tough to resist their disintegration due to impact. This distinctive property is measured by impact value test.
The strength of coarse aggregates is assessed by aggregates impact test. The aggregate impact value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, lower aggregate impact value should be preferred.
