The procedure of the impact value test includes the following series of steps: 1. The aggregate samples of size 10mm to (passing through sieve and retained on 10mm sieve) are first taken and ovendried at a temperature ranging from 100 degrees Celsius to .
METHOD B7. THE DETERMINATION OF THE TRETON IMPACT VALUE OF AGGREGATE. SCOPE The Treton value is a measure of the resistance of aggregate to impact. The aggregate is subjected to the blows of a falling hammer and the resulting disintegration is measured by means of the quantity passing the 2,0 mm sieve which is then expressed as a percentage of the test sample.
This Part of BS 812 describes a method for the determination of the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The method is applicable to aggregates passing a mm test sieve and retained on a mm test sieve. For other size fractions, there is another recommended method. The ...

Discussion AIV is used for the determination of the toughness of aggregates. Crush samples having an impact value of % fall in the egory of 1020%, therefore, the aggregate test sample is classified as strong and can be seen in the table below. The aggregate impact value is useful for selecting the good aggregates for road construction.
· Home » Transportation » Determination of Aggregate impact Value (AIV) Determination of Aggregate impact Value (AIV) 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 slowly applied compressive load.

This test method covers the determination of the Impact Value (IV) of a soil either in the field or a test mold. The standard test method, using a kg (10 lbm) hammer, is suitable for, but not limited to, evaluating the strength of an unsaturated compacted fill, in particular pavement materials, soils, and soilaggregates having maximum particle sizes less than mm ( in.). 1 ...

Keynes in his macroeconomic analysis related aggregate demand and supply to the levels of national income. Concerned as he was with the problem of an economy under .
30/03/2021 · Aggregate impact value = W2/ W1 *100. W2 – Weight of aggregate which passes through the IS sieve W1 – Weight of ovendried aggregate. For good quality aggregate, the impact value should not exceed 30% for concrete work and 45 % for base course.
07/10/2019 · Apparatus for Aggregate Impact Test Aggregate Impact Value Apparatus Balance (i) A testing machine weighing 45 to 60 kg and having a metal base with a painted lower surface of not less than 30 cm in diameter. It is supported on level and plane concrete floor of minimum 45 cm thickness. The machine should also have provisions for fixing its base.
The aggregate impact test is conducted as per IS2386 Part IV. The aggregate Impact value indies a relative measure of the resistance of aggregate to a sudden shock or an Impact, which in some aggregates differs from its resistance to a slope compressive load in crushing test. A modified Impact test is also often carried out in the case of ...
