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 10.
