This standard specifies a method for determining the 10% fines aggregate crushing value (FACT value) of a coarse aggregate sample. The FACT value is measured by crushing the aggregate sample and determining the force required to produce 10% fines, which are particles that pass through a 2,360 micrometer sieve. The test can be performed in either dry or wet conditions.
This standard specifies a method to determine the aggregate crushing value (ACV) of coarse aggregates. The ACV test involves crushing a confined sample under gradually applied force and determining the percentage crushed finer than a specified size. The standard provides details on the apparatus, sample preparation, test procedure, and expression of results for both dry and …
NOTE 1 -The 'aggregate crushing value' gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. 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. ...
The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregates possessing low aggregate crushing value should be …
This ratio is known as the Aggregate Crushing Value (ACV) and can be calculated using the following formula: Aggregate Crushing Value (ACV) = (W2 x 100) / (W1 - W) Example limits. Here is a list of the Aggregate Crushing Value limits for different types of road construction: Types of Roads / Pavements: Flexible Pavements. Water bound macadam: 40
To convert text values to numbers, you can use the VALUE function, or simply add zero as described below. In the example shown, the formula in D5 is: =VALUE(B5) As the formula is copied down it converts the text values in column B to the numbers seen in column D. Note that, by default, Excel will left-align text values and right-align numeric values.

Use the formula: Aggregate Crushing Value = 100(W2/W1) percent where: W2 = Weight of fraction passing the appropriate 2.36 mm sieve. W1 = Weight of dry sample. Normally, the percentage of fines should fall between 7.5 and 12.5. If it falls outside this range, conduct a new test at a load adjusted to bring the percentage of fines within the ...
The aggregate crushing value test followed the procedure in BS 812–110: 1990 (British Standards Institute, 1990), which is consistent with the Chinese test methods of aggregates for highway engineering, JTG E42-2005, (RIOH, 2005). The tested particle is also selected with a similar round shape, while the particle size is controlled as 9.8 ...
The aggregate crushing value test (ACV, BS 812-Part-110) is one of the test methods for determining the crushing resistance of the aggregates. Alvarado et al. and Reyes et al. concluded that the ACV test was practical, reproducible, and stable and is a pivotal method in the evaluation of aggregate crushing resistance. Friction ...
In order to estimate uniaxial compressive strength, index-to-strength conversion factors are used. These factors have been proposed by various researchers and are dependent upon rock type.

This document outlines a procedure for determining the aggregate crushing value (ACV) of road construction aggregates. The ACV test applies to aggregates between 10mm and 14mm in size. The procedure involves compacting aggregate samples into a cylinder, applying a load of 400kN over 10 minutes, then sieving the crushed material to determine the percentage passing a …
The aggregate crushing value test is normally carried out on aggregates between 10 mm and 12.5 mm in scale. In this test, a specified quantity of oven-dried aggregates (about 500g) that ...
