Aggregate Impact Value Test Apparatus

What Is an Aggregate Impact Value Test Apparatus?

The Aggregate Impact Value Test Apparatus is a laboratory testing device used to determine the resistance of aggregates to sudden impact or shock. It is a standard test recommended by IS:2386 (Part IV), BS 812, and other international specifications.

This test is especially important for aggregates used in:

  • Road construction
  • Highway pavement layers
  • Asphalt works
  • Concrete structures

Lower aggregate impact values indicate tougher and stronger aggregates, suitable for heavy-duty construction.

Applications of Aggregate Impact Value Testing

The AIV test apparatus is widely used by:

  • Construction companies
  • Engineering laboratories
  • Quality control departments
  • Infrastructure project contractors
  • Educational institutions

Common applications include:

  • Testing coarse aggregates for road works
  • Quality control in bituminous mixes
  • Aggregate performance evaluation under impact load
  • Material assessment for heavy traffic areas
