Significance of Aggregate Crushing Value Test. The crushing value test is conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load. The road is subjected to motion pressure continuously.

Test for Determination of Aggregate Crushing Value: Strength of rock is found out by making a test specimen of cylindrical shape of size 25 mm diameter and 25 mm height. This cylinder is subjected to compressive stress. Different rock samples are found to …
Procedure The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm.The aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary.
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 …

Aggregate sizes larger than 14 mm are not appropriate to the aggregate impact value test. NOTE 1 For the determination of the resistance of an aggregate to a slowly applied compressive load, see BS 812-110. NOTE 2 …
The Crushing Value test measures the ability of an aggregate to resist crushing under a compressive load. It is a measure of the strength and toughness of the aggregate. In this test, a standard crushing load is applied to a prepared aggregate sample, and the percentage of fines generated after the specified amount of crushing is determined.
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 …

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 range of 7.5 to 12.5.
The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS 2.1 An ...
