    From the experiment, the value is 29.2%, 29.8%, and 29.8% are close to the maximum allowable limit for good aggregates. Hence, they can be acceptable as their Aggregate Impact value is less than 30%. Aggregate ImpactValues, (AIV's), below 10% are regarded as strong, and AIV's above 35% would normally be regarded as too weak for use in road
