Aggregate Impact value Test Apparatus, Procedure and uses ...
Procedure of Aggregate Impact value test The test sample: normally aggregates sized 10.0 mm to 12.5 mm. the aggregates should be dried by heating at 100-110 0C for a period of 4 hours and cooled. Sieve the material through 12.5mm and 10.0 mm IS sieves. The aggregates passing through 12.5 mm sieve comprises the test material.
Aggregate impact value test- step by Step Procedure with Report
Significance of impact test. The procedure of determining aggregate impact value is according to IS 2386. More will the impact value more will be the strength of aggregate. The elongated and flaky aggregate has low strength as it has a higher surface area and gets more stress on it. Different impact value of aggregate should be used for different types of pavement given below. Recommended aggregate impact value

Determination of Aggregate Impact Value - Impact Test on ...
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 of Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled.
Impact Test on Aggregates - GharPedia
Aggregate impact value (The value of aggregate impact test) = (W1/W2)*100 The value of aggregate impact test should not be more than 45% by weight of aggregates, used for concrete other than wearing surface. An impact value 35% is permissible for the bituminous macadam. Maximum permissible impact value for the water bound macadam is 40%.
IMPACT VALUE OF AGGREGATE - iricen.gov.in
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 compressive load. 2.Apparatus Required Fig. 1: Balance Balance should be accurate upto 1 g Fig. 2: Sieves Seives required are 12.5, 10.0 and 2.36 mm Fig. 3: Impact ...
