Applications of Aggregate Crushing Test It The aggregate crushing value is an indirect measure of crushing strength of the aggregates.'" Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low.

Los Angeles abrasion test on aggregates is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. This test is carried out by AASHTO T 96 or ASTM C 131: Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine.

The LA abrasion test is the most widely used method for testing aggregate abrasion (Wu et al., 1998). In Australia, the LA abrasion method is available in the Australian Standards (AS 1141.23), whereas other standards, such as ASTM C131/C131M, may be used in other parts of the world.

Aggregate Impact Value test determines the Aggregate Impact Value (AIV) of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact. Resistance of the aggregates to impact is termed as toughness.
