The crushing value test of aggregate provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on a 10 mm sieve.
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 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for ...
The aggregate crushing value gives a related action of resistance to crushing under a gradually applied compressive load. For achieving a premium quality of pavement, an aggregate of higher crushing strength such as reduced crushing value should be selected.
Testing the compressive strength of the aggregate particles is not normally carried out to determine its strength or suitability. This property is normally determined by a simpler method such as the Aggregate Crushing Value (ACV) or the Los Angeles Abrasion test which also gives a measure of the abrasion resistance and "toughness" of the aggregate.

Crushing Value. The aggregates crushing value gives a relative measure of resistance of an aggregate to crushing under gradually applied compressive load. The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads. Impact Value
1. The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low. Hence plastic aggregates serve better as compared to stone aggregates. 2. Aggregate Impact value is dropped to a certain
The apparatus of the aggregate impact value test consists of: A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter. Level and plane concrete floor of minimum 45 cm thickness are used to support it. The base of the machine should also have provisions for fixing its base.
Aggregate impact value test also gives an indirect indication of the strength characteristics of aggregate. Aggregate impact value of a sample also depends on the shape factors such as flakiness index and elongation index of the aggregates. It has been found that for majority of aggregates, the aggregate crushing value and aggregate impact ...
The aggregate crushing strength value is useful factor to know the behaviour of aggregates when subjected to wear. 1. Crushing Test of Aggregate: 24. 25 The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact. The impact value is some times used as an alternative to its crushing value. 2.

The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes – 12.5mm, 10mm and 2.36mm Procedure to determine Aggregate Crushing Value i) The aggregates passing through …
The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of: 1) A 15cm diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in Fig 1. 2) A straight metal tamping rod of circular cross-section 16mm diameter and 45 to 60
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 …

Concept and significance of the Aggregate crushing value test. The ' aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are …
In aggregate crushing value test, the aggregate is subjected to 400 KN compression load in a cylindrical mold. The crushing value is defined by the percentage loss in mass on 2.36 mm size of test. Bigger percentage of aggregate crushing value means the aggregate is inferior in quality. According to BS 882:1992, aggregate with crushing value less
The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mold.The percentage of weight passed through the 2.36m IS sieve is known as the Aggregate crushing value..

aggregate crushing value indicates strong aggregates, as the crushed fraction is low. ~hus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components. The aggregates used for the surface course of pavements should be strong enough
The aggregates used for quality pavement should be strong enough to withstand the crushing under roller and traffic loads i.e. Low crushing value. A lower crushing value indicates a lower crushing fraction under a specific load and would give a better result, longer service life and economic performance. Aggregate crushing value test codes
