determination of aggregate crushing value 2.1 Object - This method of test covers the procedure for determining aggregate crushing value of coarse aggregate.
1) To determine the aggregate crushing value of coarse aggregates 2) To assess suitability of aggregates for use in different types of road pavement 2. PRINCIPLE 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
DETERMINATION OF AGGREGATE CRUSHING VALUE GENERAL Aggregate used in road construction, should be strong enough to resist crushing under traffic wheel load. If the aggregate are weak, the stability of the pavement structure is likely to be adversely affected. The strength of coarse aggregate is assessed by aggregate crushing test.
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 give different compressive strength
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 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.
Sampling of Aggregates. Select coarse aggregate that passes through a 12.5mm IS sieve and is retained on a 10mm IS sieve. Heat the aggregate at 100 to 110°C for 4 hours, cool it to room temperature, and ensure that the material depth in the cylinder, after tamping as described below, is 10 cm. Determine the appropriate quantity by filling …

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 …
