This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value. Granular sub-base is subjected to repeated loadings from truck types. The stress level at the contact points of aggregate particles is quite high.

Aggregate impact value analysis Products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, Aggregate impact value analysis, quarry, aggregate, and different kinds of minerals.

The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregates possessing low aggregate crushing value should be preferred.

Jul 02, 2021 · The load shall be released and the whole of the material removed from the cylinder and sieved on a 2.36mm IS sieve. The fraction retained on the sieve shall be weighed. Repeat the whole procedure for another set. The aggregate crushing value then calculated by dividing the weight passing on 2.36mm sieve with the whole sample weight in cylinder ...

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.

Aggregate Impact Crushing Value (German AIV) test (TPMin-StB-Teil 5.2.1.4,1982) and German Shape Factor (Idem, Teil 6.1.1.2) The German aggregate impact test is of different design and procedure.
