Overview. The Los Angeles () abrasion test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA.. Figure 1: abrasion testing equipment.

Aggregate abrasion value (AAV) – This test sorts out aggregates which might be strong but are not resistant to the abrasive action of vehicle tyres if used in the surface course of roads, , though suitable in every other respect, they wearout too quickly in use. In this test, 14 mm chippings are placed facedown in a rectangular mould.

The crushing test on aggregate gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregates.
