A laboratory test involving the mechanical stabilization of RCA and CG was conducted to examine their physical properties. . The aggregate crushing value is an essential index in the . Then crushed aggregates are then sieved through 2.36 mm sieve and weight of passing material (W2) is expressed as percentage of the weight of the total sample (W1) which is the aggregate crushing value. Aggregate crushing value = (W1/W2)*100. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be .Aggregate Crushing Value Test . 1. objective. 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 . This test is similar to the Aggregate Crushing Test (ACV), which applies a standard force of 400kN and expresses the fines material as a percentage of the original mass, known as the aggregate crushing value. The granular sub-base is subject to repeated loadings from various truck types, causing high levels of stress at the contact points of .
Sieve the test material through 12.5 mm and 10.0 mm IS sieve. Take test samples of aggregates passing through 12.5 mm IS sieve and retained on 10 mm IS sieve (minimum 3 Kg).; Dry theme in an oven for 4 hours at a temperature of 100 .Transportation Engineering Laboratory Bachelor of Technology . AGGREGATE CRUSHING VALUE TEST Objective: To determine crushing strength of given aggregate sample IS Standards used: IS-2386 Part- 4 and BS: 2009 Need and scope: This is one of the major mechanical properties required in a road stone. The test evaluates the

If .compressive load. With aggregate of aggregate impact value (AIV) higher than 30 the result may be anomalous. Also aggregate sizes larger than 14 mm are not appropriate to the aggregate impact test. The standard aggregate impact test shall be made on aggregate passing a 14. mm BS test sieve and retained on a 10.0 mm BS test sieve.
During the laboratory the dry test was conducted, that is, the aggregate was in surface dry condition. The procedure was followed up to giving results of the tests. These tests are a measure of the crushing properties of the .per cent material passing a specified sieve after crushing. The procedure described in SABS Method 842 is followed. Definition The 10 per cent Fines Aggregate Crushing Value is the force in kN required to crush a sample of -13,2+9,5mm aggregate so that 10 per cent of the total test sample will pass a 2, 36 mm sieve. 2 APPARATUS As in SABS .
