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
The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110 C for a period of 4 hours and cooled.
aggregate samples to calculate the LA abrasion loss. The authors found that the LA abrasion test was a consistent method of detecting weak materials and was a means of pre dicting aggregate impact value and aggregate crushing value. Wylde 11 reviewed and investigated the road failures,

The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30. If it is more than 30 then 10 finer aggregate is suggested to use. The aggregate whose crushing value is less than 30 can be used for ...

Jan 20, 2020 Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt PA mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, step-loading compression tests were conducted on the mixtures of PA-13 and a control asphalt mixture AC-13, respectively.
