Aggregate crushing value is determined by taking a percentage of weight crushed aggregate sample passing through 2.36 mm IS Sieve divided by weight of aggregate sample taken for test Aggregate crushing value formula is given below, Aggregate crushing value W3 W or W3 W2 W1 W1 Empty weight of cylindrical Measure. W2 Weight of Aggregate with Cylindrical Measure
Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm 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 W2W1 x 100. Lab Report

Dec 15, 2017 11. 11 CONCLUSION From the experiment, we get the value is 17 and 15less than the requirement of JKRs 20.Aggregate physical property must lower Aggregate Impact Value, AIV because is tougher and resistance to crushed. We can conclude that the aggregate been used are medium toughand resistant to be crash.
Abrasion Test. Measurement of toughness and resistance like degradation, crushing, and disintegration is the right definition of the Abrasion test.. This test is suggested by AASHTO T 96 or ASTM C 131 Resistance to degradation of small coarse aggregates by Abrasion and impact on the Los Angeles Machine.. Aggregates are used for the surface course of road pavements and are subject to wear and ...

The aggregate impact values are strong on the average, by about 10 to 30 than 8 the aggregate crushing values. Various agencies have specified the maximum permissible aggregate impact values for the different types of pavements, those recommended by the roads for deciding the suitability of soft aggregates in base course construction, this test has been commonly used.

Aggregate Crushing Value ACV is an index of loss of coarse aggregate CA under sustained loading. However, ACV is not considered in concrete mix design according to ACI 211.1ACI 211.1, 2009. In this paper effect of ACV of CA on compressive strength of concrete has been explored. Coarse
Impact, 10 Fines amp Crushing TestsIf the percentage fines exceeds 30, the result may be anomalous as the brokenpieces of aggregate will tend to fill the voids and prevent further crushing. Inthis case, the Ten Percent Fines Test is more appropriate.

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

8. Recommended Crushing Value Standard of Coarse Aggregate in PA Mixture. In 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 261.48 17.6.
Impact and Crushing Value Aggregate Crushing Value ACV Sets. UTA-0630 Aggregate Crushing Value ACV Set 150 mm BS. UTA-0640 Aggregate Crushing Value ACV Set 75 mm BS. The Aggregate Crushing Value ACV Test Set measures how resistant an aggregate is, when being crushed under a gradually applied compressive load.
Jan 04, 2014 Procedure of testing Aggregate Crushing Value ACV 1. Make a sieve analysis and get sufficient amount of aggregate by using 14.0 mm passing sieve and 10.00 mm retained sieve. 2. After sieving fill the cylinder in thre layers by the aggregate and apply 25 blows by the tamping rod with a approximate height of 50 mm. 3.
