Determination of Aggregate Impact Value – Impact Test on. Determination of aggregate impact value ␓ impact test on aggregates is done to carry out to: determine the impact value of the road aggregates, assess their suitability in road construction on the basis of impact value. The aggregate retained on the sieve is weighed and the difference between this weight and the original weight is expressed as a percentage and reported as the l.a. abrasion loss value. introduction tests for resistance to abrasion in crushed rock, slag, crushed and uncrushed gravel can using los angeles testing method..
