The la abrasion test is a standard method for measuring the abrasion resistance of unbound granular materials kahraman et al.The values obtained from the la abrasion test are principally measures of the breakdown of the materials caused by impact and degradation during handling, batching and lay-down operations meininger, 2004.
Aug 19 2008 aggregate crushing value standard the aggregate crushing value acv of an aggregate is the mass of material expressed as a percentage of the test sample which is crushed finer than a 236 mm sieve when a sample of aggregate passing the 132 mm and retained on the 950 mm sieve is subjected toaggregate crushing value standard.
Aggregate crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load in situations, when aggregate value 30 or higher the result may be a mistake and in such cases, the ten percent fines value should be determined and used instead.
