Read MoreThis percentage is known as a crushing value of aggregate. This percentage should not exceed 30 of the total weight of aggregate taken for the test. The aggregate crushing value test result should not be more than 30 for the concrete used for roads and pavements and, in case of other structures it may be permitted up to 45.
Read MoreAggregate 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
