getting reproducible results. On the contrary, the aggregate crushing test is simple, rapid and gives fairly consistent results. Application of Aggregate Crushing Test: The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low.

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 (Figure 1) 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.

Sampling for Crushing Test of Aggregate. For the Aggregate crushing value test, an aggregate sample passing through a 12.5 mm IS sieve and retained on a 10mm IS sieve is selected and dried to a temperature of 105 ºC to 110 ºC then cooled to room temperature. To fill the cylindrical measure mold about 6.5 kg of a sample of aggregate is sufficient.

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.

The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing apply a gradually increasing compressive load. The strength of aggregate is calculated by the crushing value test. The aggregates used should be strong enough to with stand the stresses which comes on to it. Aggregate are the important part of

TESTING OF AGGREGATE CRUSHING VALUE. Aggregate crushing value is an indicator of the crushing resistance of the aggregates when a compressive load is increased. It is tested in accordance with BS 812:110, 1990 and aggregate passing a 14mm test sieve and retained on 10mm sieve are considered for the testing. The allowable range is 17- 41.

6. Impact, 10% Fines & Crushing Tests If the percentage fines exceeds 30, the result may be anomalous as the broken pieces of aggregate will tend to fill the voids and prevent further crushing. In this case, the Ten Percent Fines Test is more appropriate. Some countries, e.g., Australia and New Zealand, only use the latter test.
