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 Required Fig 1 Balance Balance should be accurate upto 1 gm Fig 2 Sieve
2021 04 26· The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS here sieve to the total weight of sample expressed in percentage W1= Weigh of the total aggregates Wa We W2= Weigh of aggregates passing through IS sieve Aggregate crushing value= W2 / W1 × 100
· AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 Part IV 1963 The apparatus used is Cylindrical measure and plunger Compression testing machine IS Sieves of sizes 10mm and Procedure to determine Aggregate Crushing Value i The aggregates passing through and retained
standardized by IS 2386 part IV and used to determine the crushing strength of aggregates The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load The test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions Figure 22 1 Dry aggregates passing through
Effect Of Aggregate Properties On The Crushing Strength Sep 05 2021 Test for Determination of Crushing Value of Aggregate The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load With aggregates of aggregate crushing value 30 or higher the result may be anomalous and in such cases the 10 fines value
The aggregate size fraction taken for this test can also be as per the relevant national standards NOTE Minor variations in grading divisions can be allowed in respective national standards The method is not suitable for testing aggregates with an aggregate crushing value higher than 30 In such cases the method described in ISO 20290 4 is

Pdf standard of crushing value of coarse aggregates forpdf standard of crushing value of coarse aggregates forTo determine the technical requirements of crushing value of coarse aggregate used in pa mixture steploading compression tests were conducted on the mixtures of pa13 and a control asphalt average crushing value of aggregate
Calculate Aggregate Crushing Value The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage the result being recorded to the first decimal place Aggregate Crushing Value = W B W A × 100 Where W A is weight of surface dry sample
The crushing value of aggregates is measured in the ratio between the crushed aggregates obtained from the IS sieve and the weight of the dried aggregate sample At least three samples should be tested from the same batch and average value to get accurate results The crushing value of aggregate = W2/W1 x 100
Standard of Crushing Value of Coarse Aggregates forIn current Chinese technical specification the crushing value of the coarse aggregate for surface layer of asphalt pavement is no greater than 26% So the crushing value standard of basalt coarse aggregate used in PA mixture should be increased to not more than 26%/ = % As for diabase aggregate it should be no more than 26%/1
