The Aggregate Crushing Value (ACV) test is a fundamental measure of a material's resistance to crushing under a compressive load. It is widely used in the …
The test requires samples of the aggregate to be subjected to standard load crushing conditions. Multiple layers of presieved materials are tamped 25 times before a 40-ton load is applied at a rate of 4 tons per minute. The crushed aggregate is then sieved, weighed, and compared to the original total weight to provide an aggregate crushing …
The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead. ... The machine may be used with or ...
About 6.5 kg of natural aggregate is required to provide the two test samples. Use less light-weight aggregate. Calculate the percentage of fines generated to the total sample weight. Use the formula: Aggregate Crushing Value = 100(W2/W1) percent where: W2 = Weight of fraction passing the appropriate 2.36 mm sieve. W1 = …
Procedure of Aggregate Impact value test. The test sample: normally aggregates sized 10.0 mm to 12.5 mm. the aggregates should be dried by heating at 100-110 0C for a period of 4 hours and cooled.
The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregates possessing low aggregate crushing value should be preferred. ...

Explanation: The aggregate crushing value provides a relative measure of a maximum value of 40%age is allowed for WBM base course in Indian conditions. 7. Aggregates to be used for wearing course ...
It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be …
Observations of Los Angeles Test Original weight of aggregate sample = W 1 g Weight of aggregate sample retained = W 2 g Weight passing 1.7mm IS sieve = W 1 - W 2 g Abrasion Value = (W 1 - W 2 ) / W 1 X 100 Results Los Angeles Abrasion Value = Recommended Los Angeles Test Values for Pavements Los Angeles test is commonly …
