The Abrasion test uses larger dry samples and abrasive charges in a drum with a shelf. The shelf lifts and drops the sample and abrasive charge across the span of the drum, resulting in a very high impact on the aggregate particles. Loss from this test is a result of fracturing and dry grinding of the particles.

Sep 12, 2015· The crushed aggregate is allowed to pass through mm IS sieve. And the impact value is measured as percentage of aggregates passing sieve (W2) to the total weight of the sample (W1). Aggregate impact value = (W1/W2)*100. Aggregates to be used for wearing course, the impact value shouldn't exceed 30 percent.
