The principle of the Los Angeles abrasion test is to find the percentage wear due to relative rubbing action between the aggregate and mass traffic.
What types of aggregates should be avoided?
Polishing prone aggregates are to be avoided as this can lead to a loss of skid resistance.

The primary role of the coarse aggregates in this case is to maintain the built-in texture.
