This Part of BS 812 describes a method for the determination of the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve.

Since 1979 the Institute for Transport Sciences /KTI/ in Hungary has dealt with abrasion tests. This testing method is an adaptation of British Standard BS 812:P.3.9:1975. The results obtained are as follows: -The Hungarian testing method is based on oven-dried chippings -The Hungarian method considers the actual chipping volume. -The actual abrasion value can be determined with ±5% …

Overview BS 812-113:1990 Testing aggregates. Method for determination of aggregate abrasion value (AAV): This British Standard, a part of the BS 812 series, describes a method for the determination of the aggregate abrasion value (AAV) which gives a measure of the resistance of aggregates to surface wear by abrasion.
This British Standard, a part of the BS 812 series, describes a method for the determination of the aggregate abrasion value (AAV) which gives a measure of the resistance of aggregates to surface wear by abrasion. The aggregate abrasion value is determined from the differences in mass of the specimens before and after abrasion.
Aggregate abrasion value (AAV) – Resistance of an aggregate to abrasion as measured in the aggregate abrasion test. The smaller the value, the higher the resistance to abrasion. (BS 812–113: 1990) (Smith and Collis 1993). Aggregate colour – The colour of an aggregate can be affected by its moisture content and the quantity of adhering fines.
