Aggregates to be used for wearing course, the impact value shouldn’t exceed 30 percent.. For bituminous macadam, the maximum permissible value is 35 percent. For Water bound macadam base courses the maximum . The British standard Aggregate Impact Test method fundamentally differs from Eurocode recommendations (BS 812-112: . The correlation between Aggregate Impact Value (AIV) and crushing values (ACV) was direct and linear like the previous relationships. . The difference in the shape of the grain size distribution curves led to the conclusion .
The relevant standards for this test include British Standard BS 812-3 and European Standard EN 1097-8 Aggregate Abrasion Value (AAV) Test. Although specified in an earlier version of BS 812, the current AAV test, which was introduced in 1951, has superseded the Dorry Abrasion Test.
