Procedure to determineAggregate CrushingValue i) Theaggregatespassing through 12.5mm and retained on 10mm IS Sieve are oven-dried at a temperature of 100 to 110 o C for 3 to 4hrs. ii) The cylinder of theapparatusis filled in 3 layers, each layer tamped with 25 strokes of a tamping rod. iii) The weight ofaggregatesis measured (Weight ‘A’).
May 05, 2010· Calculation ofAggregate Crushing Value. The ratio of weight of fines formed to the weight of total sample in eachtestshall be expressed as a percentage, the result being recorded to the first decimal place.Aggregate crushing value= (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve. W1-W =Weight of surface dry sample.

For abrasion and durability testing, Humboldt manufactures a high-quality Los Angeles abrasion machine used to measure the degradation of mineral aggregate of standard gradings resulting from a combination of actions including abrasion or attrition, impact and grinding in a rotating steel drum containing a specified number of steel spheres.
AggregateTestingEquipment. Asaggregatesare used as a component of many construction materials, asphalt, concrete and also raw as road base or ballast there are many methods for characterising its geometry, mechanical an physical properties and its resistance to wear.
The Los Angeles test is a measure of degradation of mineral aggregates of standard gradings resulting from a combination of actions including abrasion or attrition, impact, and grinding in a rotating steel drum containing a specified number of steel spheres. The Los Angeles (L.A.) abrasion test is a common test method used to indicate aggregate toughness and abrasion characteristics.
The crushing value test is conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load. The road is subjected to motion pressure continuously.
