Aggregate Impact Values, (AIV's), below 10 are regarded as strong, and AIV's above 35 would normally be regarded as too weak for use in road surfaces. Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties. Aggregate Impact Value; Test Specifications:

Jul 16, 2014 · Aggregate impact value test gives an indication of aggregate's toughness property (i.e. property of a material to resist impact) Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. Aggregate impact value (%) Toughness Properties <10 Exceptionally tough / Strong 10 – 20 Very tough / Strong [.]

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.

number. Report the mean as the Aggregate Crushing Value, unless the individual results differ by more than 0.07 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number and report the median as the Aggregate Crushing Value. A data sheet is given as Form 7.7.1.

Different Types of Test on Aggregate. In order to decide the suitability of the aggregate for use in concrete/pavement construction, following tests are carried out: 01. Crushing Test on Aggregate.

The standard aggregate impact test shall be made on aggregate passing a 14.0 mm BS test sieve and retained on a10.0 mm BS test sieve. If required, or if the standard size is not available, smaller sizes may be tested but owing to the non-homogeneity of aggregates the results are not likely to be the same as those obtained from the standard size.

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.
