aggregate crushing logangles test procedure

Purpose of this test covers the procedure to determine the aggregates crushing value of coarse aggregates. Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load

• Aggregate Crushing Value Test - Procedure And Result

Oct 03, 2019 For the Aggregate crushing value test, an aggregate sample passing through 12.5 mm IS sieve and retained on 10mm IS sieve is selected and dried to a temperature of 105 C to 110 C then cooled to room temperature. To fill the cylindrical measure mould about 6.5 kg of a sample of aggregate is sufficient

NOTE 1 -The ‘aggregate crushing value’ gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggre- gate 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. NOTE 2 - The standard aggregate crushing test shall be made on aggre

May 17, 2019 Take the aggregate out of the cylinder and sieve them through a 2.36 mm IS sieve. Weight this fraction passing through it to an accuracy of 0.1 gm. This fraction is a quantity of the loss of material due to crushing. Note down the observations in the proforma then compute the aggregate crushing value

• Los Angeles Abrasion Test Procedure, Method, Significance

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
