Aggregate crushing value conclusion aggregate crushing value test determines aggregate crushing value coarse aggregate test gives relative measurement value of aggregate crushing resistance under gradually applied compression load. Coarse aggregate crushing value is the weight percentage of crushed material obtained during the test.
Percentage of aggregate crushing value w2w1100 2643 recommended value of aggregate crushing value w2w1 100 7712917 100 2643 recommended value according to its proposed use in pavement layer, the applicability of aggregate is judged, and the following percentage limits of aggregate crushing value for different types of road construction are specified.
The test device for aggregate crushing value is used to measure the crushing resistance of aggregates made of low carbon steel. The test device consists of a cylindrical hole with a diameter of 150 mm, a plunger with a height of 130-140 mm, a bottom plate with a diameter of 148 mm × 100-115mm, and a bottom plate of 200-230mm square × 6mm thick.
Aggregate crushing value test procedure and results aggregate crushing value test selected aggregate samples passing the 125 mm is sieve and retained on the 10 mm is sieve, dried to 105 186 C to 110 186 C and then cooled to room temperature to fill approximately 65 KGA.
August 11 2020018332 this test is repeated once or twice and the average crushing value of aggregate is determined. The average crushing value in different tests is the actual crushing value of aggregate. Note: it is recommended that the crushing value of aggregate should be less than 30.

Difference between aggregate crushing value and aggregate impact value Scribd aggregate crushing value test manual 77 aggregate crushing value and 10 fine aggregate value 771 Chapter 7 standard test procedure for aggregates and bricks.
Aggregate crushing value test discussion aggregate crushing value test discussion aggregate impact test paper November 3, 2009 test methods include procedures for determining the impact value of coarse aggregate. The main advantage of aggregate impact test is that the test equipment and test procedure are quite simple and its resistance is low.
Discussion on aggregate crushing value test the relative measurement value of aggregate crushing resistance under gradually applied compression load is given. The aggregate crushing value is defined as the specified load when the test aggregate is subjected to standard conditions.
March 27 2020018332 application of aggregate impact value aggregate impact test is considered to be an important test to understand the applicability of aggregate toughness in pavement construction. It has been found that for most aggregates, the aggregate crushing value and aggregate impact value are numerically similar closure limits.

Therefore, the aggregate used for such recommendations should be sufficiently ductile to resist disintegration due to impact. The important properties of aggregate are determined by impact value test. The resistance of the aggregate may be different from that measured in the crushing value test - significant impact value test to the gradual load.
