The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100110 C for a period of 4 hours and cooled.

Aggregate Impact Value Test Specifications Aggregate Impact Value. The test sample shall consist of aggregates the whole of which passes through in B.S. test sieve and is retained on a 38 in B.S. test sieve. The aggregate comprising the test sample shall be dried in an oven for a period of four hours at a temperature of 100110 C and
Aggregate Impact Values, AIVs, below 10 are regarded as strong, and AIVs above 35 would normally be regarded as too weak for use in road surfaces. Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties. Recommended Aggregate Impact Test Values
The aggregate impact value is expressed as the percentage of the fines formed in terms of the total weight of the sample. 100 W2 Where, W1 Original weight of the sample. Aggregate Impact Value W1 W2 Weight of fraction passing 2.36mm IS sieve.
To evaluate the toughness of a stone i.e. the resistance of the aggregates to fracture under repeated impacts is called Impact test is done to determine the aggregate impact value of coarse aggregate as per IS 2386 PartIV 1993. Aggregate Impact Value Test as per IS 2386 PartIV 1993
The aim of aggregate impact test is to determine the relative measure of the resistance of aggregate to sudden shock or impact in which in some aggregate differs from its resistance to a slowly applies compressive load. The property of a material
AIV test is conducted to determine the Aggregate Impact Value of Coarse aggregate. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from Its resistance to a slow compression load. The Indian Standard CODE IS 2386 Part IV 1963 is used for
The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100110 C for a period of 4 hours and cooled.

The test aims at looking for the forces required to produce 10 of fine values i.e. weight of fines aggregatesweight of all aggregates 10. This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.
Aggregate impact value test gives an indication of aggregates toughness property i.e. property of a material to resist impact Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. Aggregate impact value Toughness Properties lt10 Exceptionally tough Strong 10 20 Very tough Strong
nearest whole number. Report the mean as the aggregate impact value, unless the individual results differ by more than 0.15 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number and report the median as the aggregate impact value.

This test is done to determine the aggregate impact value of coarse aggregates as per IS 2386 Part IV 1963. The apparatus used for determining aggregate impact value of coarse aggregates is. Impact testing machine conforming to IS 2386 Part IV 1963,IS Sieves of sizes 12.5mm, 10mm and 2.36mm, A cylindrical metal measure of 75mm
Aggregates Impact Test AIV Introduction Impact value of an aggregate is the percentage loss of weight particles passing 2.36mm sieve by the application of load by means of 15 blows of standard hammer and drop, under specified test condition. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from
aggregate samples to calculate the LA abrasion loss. The authors found that the LA abrasion test was a consistent method of detecting weak materials and was a means of pre dicting aggregate impact value and aggregate crushing value. Wylde 11 reviewed and investigated the road failures,

Aggregates Impact Test Conforming to IS 2386 Part 41963 With respect to concrete aggregates toughness is also consider. The resistance of the material to failure by impact is known as toughness. The aggregates should therefore have suffic
Objective 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different types of road. Theory The 34 aggregate crushing value 34 give a relative measure of the resistance of
design by Dri Sirly for Prezi AGGREGATE IMPACT TEST In conclusion,the percentage of aggregates wear depends on the quality of aggregate. In this test, we can conclude that The loss of aggregate 1663 g The percentage of wear 33.26 Lower abrasion loss values indicate the
