Aggregate Crushing Value Test – Determine …
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 subjected to a specified load under standardized conditions, and the strength of the aggregate used in road …

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 – 12.5mm, 10mm and 2.36mm. Procedure to determine Aggregate Crushing Value
Aggregate Crushing Value Test -Determine …
Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.
Aggregate Crushing Value Test - Learning …
The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed (or finer) material obtained when the test sample is subjected to a specified load under standard conditions. Aggregates with lower crushing value indicate a lower crushed fraction under load or higher strength and would provide a longer service life to the structure…

Home » Transportation » Aggregate Crushing Value (ACV) Aggregate Crushing Value (ACV) The aggregate Impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slowly applied compressive load. With aggregate of aggregate impact value higher than 30 the result may be anomalous. Also, aggregate ...
Aggregate Crushing Value Test - Procedure and …
Aggregate crushing value 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 10 mm sieve. The aggregate sample is filled in a cylindrical mold and a load of 40 ton is applied through a plunger in a compression testing machine. The crushed aggregate sample which is ...

Table 5.4 presents the statistical data of the LA abrasion mass loss, aggregate crushing value (ACV) and aggregate impact value (AIV) obtained from 307 RA samples. As expected, the LA abrasion results suggest that the resistance to fragmentation of RA, in descending order, is RCA, MRA and RMA. However, this trend is not clear in the case of AIV and ACV.

Test method T205 - rms.nsw.gov.au
aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing. The standard test is made on dry aggregate passing a 13.2 mm AS sieve and retained on a 9.50 mm AS sieve and is performed in duplicate.
DETERMINATION OF AGGREGATE CRUSHING VALUE
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 crushing value. 3. APPARATUS The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of: 1) A …
