5.1 This test has been widely used as an indicator of the relative quality or competence of various sources of aggregate having similar mineral compositions. The results do not automatically permit valid comparisons to be made between sources distinctly different in origin, composition, or structure.
The aggregate crushing value (ACV) provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two versions available: 150 …

The aggregate impact test is considered to be an important test to assess the suitability of aggregates as regards the toughness for use in pavement construction. It has been found that for majority of aggregates, the aggregate crushing and aggregate impact values …
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.
The Los Angeles (L.A.) abrasion test is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and …
BS 812 part 110 describes a method to determine the aggregate crushing value (ACV) which gives a relative measure of the crushing resistance of aggregate under an increasing compressive load.The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve.
PURPOSE OF TEST: The strength of coarse aggregate is assessed by aggregate crushing test, the aggregate value provide the relative measure of resistance to crushing under gradually applied compressive load. ...
(1) ARESULTSAn average is taken of the two tests and the result is recorded to the nearestwhole number as the Aggregate Impact Value.The AIV is normally about 105 per cent of the Aggregate Crushing Value and itcan be used for the same purpose.
Experiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. (BS 812) Scope & significance: Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.
The Los Angeles (L.A.) abrasion test is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA.
