Discussion (LA Abrasion Test) Lab Report
It is important because the constituent aggregate must resist crushing, degradation and disintegration in order to produce a high quality. For this experiment, the LA Abrasion value obtained was 6.54 % and 9. %. based on the JKR Specification, the aggregate for use in bituminous road surfacing is maximum 40%.

Aggregate Impact Value Test | Impact Test Of Aggregate
Therefore, aggregate used for such propose should have sufficient toughness to resist their disintegration due to the impact. This important property of aggregate is determined by the aggregate impact value test. This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test.
