Lab 3: Determination of aggregate impact value (AIV) of given aggregate sample (BS-812) 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. Increase in impact value will indicate reduction in…
