The test results are used for the quality control, by means of particle strength, of aggregates for concrete, surfacing (chips) and asphalt, and for crushed stone base. The 10 % fines aggregate crushing test (FACT) value is preferred when the aggregate crushing value (ACV) exceeds 30 %, and the result may then be unreliable.
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. i) The aggregates passing through 12.5mm and retained on 10mm IS Sieve are oven-dried at a …
The 10% fines value is a metric that gauges the ability of aggregates to withstand crushing under loading, and it is applicable to both weak and strong aggregates. Fine aggregates are those that pass through a 2.36mm sieve. This test seeks to determine the amount of force required to produce 10% of fine values, which is expressed as the …

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 ...
The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve. For other size fractions, a recommended method is described in Annex A . The aggregate size fraction taken for this test …
Result: Aggregate crushing value = 20%. Result Analysis: The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. Aggregate crushing value < 45% for aggregates used for concrete for non-wearing surfaces and <25% for wearing surfaces like runways and …
Smaller sizes may also be tested (see Note 2 under 2.6). IS : 2386 (Part IV) '- 1963. 2.2 Apparatus - The apparatus for the standard test shall consist of the following : a) A 15-cm diameter open-ended steel cylinder, with plunger and base-plate, of the general form and dimensions shown in Fig. 1.
The aggregate crushing value test is conducted on coarse aggregates to determine their resistance to crushing under gradually applied compressive load. It is …

Aggregate Crushing Value Test. The objective of this test is to: Determine the aggregate crushing value of coarse aggregate. Assess suitability of …
Crushing Test Fig-1 Crushing Test Setup. One of the model in which pavement material can fail is by crushing under compressive stress. A test is 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 …
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. ... So Crushing value test is …

5.1 Impact Value, as determined using the standard 4.5 kg (10 lbm) hammer, has direct application to design and construction of pavements and a general application to earthworks compaction control and evaluation of strength characteristics of a wide range of materials, such as soils, soil aggregates, stabilized soil and recreational …
The aggregate crushing test can be used to determine the strength of coarse aggregate. The aggregate crushing value is a relative measure of crushing resistance under a continuously applied compressive stress. Aggregates with strong crushing resistance or a low aggregate crushing value are preferred for use in high …
The aggregate crushing value is obtained by the following expression: Aggregate crushing value = (frac{W1}{W2} times 100) W2 = Total weight of the dry sample. W1 = Weight of material passing 2.36 mm I.S. sieve. Additional Information The aggregate crushing value should not be greater than 30% for the surface course and …
The crushing characteristics of coarse aggregates for asphalt concrete were investigated under static and dynamic aggregate crushing value tests (ACVTs). The effect of various compaction loads was also examined by using a Marshall hammer, gyratory compactor and steel roller. Six types of coarse aggregates were tested, …
This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve.
The 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. W = W2 –W1 = Weight of Aggregate Sample. W3 = Weight of crushed … See more
