may 27, 2020 the crushing value of an aggregate indicates its resistance against crushing under gradually applied compressive loads. the standard aggregate crushing test is made on aggregate passing 12.m IS sieve and retained on mm IS sieve. procedure. about 6.5 Kg material consisting of aggregates passing 12.m IS sieve and retained on sieve is
crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt PA mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, step-loading compression tests were conducted on the mixtures of pa-13 and a control asphalt mixture ac-13, respectively.
aggregate crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load In situations, when aggregate value or higher the result may be a mistake and in such cases, the ten percent fines value should be determined and used instead.
the standard aggregate impact test shall be made on aggregate passing a 14.0 mm BS test sieve and retained on mm BS test sieve. If required, or if the standard size is not available, smaller sizes may be tested but owing to the non-homogeneity of aggregates the results are not likely to be the same as those obtained from the standard size.
aggregate crushing experiment values. experiment determination OF aggregate crushing value aim the aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load crushing value is a measure of the strength of the aggregate the aggregates should therefore have minimum.
feb 03, 2012 from the experiment, we get average percent wear are 22.34 still not exceeding jkrs standard, 30. So we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.

aggregate crushing value depends on the shape of agg also. angular aggregates have a lower acv, than irregular or rounded aggregates.if we cut a core out of the same agg say in the quarry and test for compressive strength, will give a higher mpa value. It can be considered as a concrete cylinder or ucs tested in lab. So it is hard to corelate

the average crushing value in the different tests is the actual crushing value of aggregate. important points to remember. It is recommended that the crushing value of aggregate should be less than 30. If it is more than then finer aggregate is suggested to use. the aggregate whose crushing value is less than can be used for cement concrete road. the aggregate whose crushing value
