### Exp 4 Aggregate Impact ValueCivil Engineers PK

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.
