2021-9-2 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. The road is subjected to motion pressure continuously.

More2021-8-11 The test conducted to know the compressive strength of aggregate is known as aggregates crushing value test. The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced.
