DETERMINATION OF AGGREGATE IMPACT VALUE (AIV) (BS 812112) Scope This Part of BS 812 describes methods for the determination of the aggregate impact value (AIV) which gives a relative measure of the resistance of an aggregate to sudden shock or impact. Principle A test specimen is compacted in a standardized manner into an open steel cup.
Aggregate Impact an overview ScienceDirect Topics. Table presents the statistical data of the LA abrasion mass loss aggregate crushing value (ACV) and aggregate impact value (AIV) obtained from 307 RA samples. As expected the LA abrasion results suggest that the resistance to fragmentation of RA in descending order is RCA MRA and RMA.
Determination of aggregate impact value (AIV) of given aggregate sample (BS812) Significance Aggregates used in the construction of roads should be strong enough to resist crushing under traffic wheel loads. It gives relative measure of the resistance of an aggregate to sudden shock or impact.

For the BS 812112 method a small portion of 1410mmsized coarse aggregate particles is confined in a steel pot and subjected to 15 blows by a small hammer in a standardised test rig after which the aggregate impact value (AIV) is determined from the fine material generated expressed as a percentage of the original weight of the
Experiment No. 4 Method for determination of Aggregate Impact Value (AIV) under dry conditions. Code (BS812) Purpose The aim of this method is to determine the 1) Impact Value of road aggregates. 2) To assess the suitability of aggregates for use in different types of road pavements.
The aggregate impact value indicates a relative measure of the resistance of the aggregate to a sudden shock or impact which in some aggregates differs from its resistance to a slow compressive load. From the calculations done we know that the aggregate can be acceptable as their Aggregate Impact value is less then 20 Aggregate Impact Value
