    Uses Of The Abrasion Test. For an aggregate to perform satisfactorily on the pavement, it must be difficult enough to resist the abrasive effect of traffic for a long period of time. Soft aggregates will be quickly crushed into powder, while hard aggregates are quite resistant to crushing. The test will also determine the quality of the aggregate.
