Aggregate Crushing Value Significance Amp Test Procedure

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.

Exp 4 Aggregate Impact Value Civil Engineers Pk

Aggregate Impact Values AIVs below 10 are regarded as strong and AIVs 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
