The Los Angeles (L.A.) abrasion test 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.
BS 812 part 110 describes a method to determine the aggregate crushing value (ACV) which gives a relative measure of the crushing resistance of aggregate under an increasing compressive load.The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve.
3.2. Aggregate Crushing Value (ACV) Determination . The Aggregate Crushing Value is a value which indicates gradually applied compressive load (a California Bearing Ratio (CBR) machine or concrete crushing apparatus) over a period of 10 minutes, after passing through sieve 14.0mm, and retained on 10.0mm sieve. The retained materials were
