Generally, the CBR value at 2.50mm penetration will be greater than that at 5.00mm penetration and is such case takes the value at 2.50mm as the CBR value. If the CBR value corresponding to a penetration of 5.00mm exceeds that of 2.50mm, we need to repeat the test. In this case, the value is acceptable.

Significance of Aggregate Crushing Value Test. The crushing value test is conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load.
