Aggregate Impact Tester
Product Code : EL-ATLE-10467
Aggregate Impact Tester (code EL-ATLE-10467) is an apparatus for finding the aggregate impact value (AIV), a relative measure of how well an aggregate resists sudden shock or impact. A 13.75 ± 0.25 kg hammer falls freely down two vertical guides on a circular base from a height adjustable through 380 ± 5 mm, a counter records the blows, and a 75 mm × 50 mm metal measure and a 230 mm tamping rod are supplied.

What Is the Aggregate Impact Tester Used For?
Aggregates in road surfaces and pavement layers are struck repeatedly by traffic, so their resistance to sudden impact is checked before use. The operator fills the metal measure with the test fraction, tamping it with the rod, compacts the sample in the apparatus and releases the hammer down the guides for the required number of blows, which the counter records. The material is then sieved, and the fines produced, expressed as a percentage of the sample mass, give the impact value; the lower the value, the tougher the aggregate.
What to Specify When Ordering
- Quantity — the number of impact testers required.
Frequently Asked Questions
What does the aggregate impact value tell an engineer?
It is a relative measure of an aggregate's resistance to sudden shock or impact; a sample that breaks into more fines under the hammer has a higher value and lower toughness.
How heavy is the hammer and how far does it fall?
The hammer weighs 13.75 ± 0.25 kg and falls freely down two vertical guides, with the height of fall adjustable through 380 ± 5 mm.
How are the blows counted?
A blow counter fitted on top of the tester automatically records each blow delivered to the sample, and the hammer is provided with a locking arrangement.
What is the tester made of?
It is built from heavy duty plated steel to resist corrosion, with a circular base carrying the two vertical guides for the hammer.
What accessories are supplied with it?
It comes with a metal measure 75 mm in diameter and 50 mm high for specimen preparation, and a tamping rod 230 mm long and 10 mm in diameter.
Which standards are listed?
The standards listed for the Aggregate Impact Tester are IS 2386 (Part IV), IS 9377 and BS 812:112.
